Measurement device having a plurality of sensors disposed in movable arms

FIELD

The present technology pertains to a measurement device operable to track fluid flow parameters. In particular, the present disclosure relates to a system and method for monitoring various parameters of a dynamic fluid flow using a measurement device having a plurality of sensors disposed on one or more moveable arms.

BACKGROUND

Current devices used for monitoring fluid flow parameters within a fluidic channel typically include one of a single line of sensors spaced along the diameter of the channel or a plurality of sensors embedded in the side of the fluidic channel Sensor arrangements, such as those dispersed along the diameter of the fluidic channel, are not hydrodynamic and can disrupt the fluid flow throughout the area to be measured, which can result in erroneous readings and inaccurate information. Additionally, in systems where sensors are embedded within the walls of the fluidic channel, the sensors are spread out over a wide area, which can be insufficient to obtain a full understanding of the fluid flow properties throughout the fluidic channel. Collection of limited data as described can lead to inefficient and inaccurate measurements of the dynamic flow.

DETAILED DESCRIPTION

Various embodiments of the disclosure are discussed in detail below. While specific implementations are discussed, it should be understood that this is done for illustrative purposes only. A person skilled in the relevant art will recognize that other components and configurations may be used without departing from the spirit and scope of the disclosure. Additional features and advantages of the disclosure will be set forth in the description which follows, and in part will be obvious from the description, or can be learned by practice of the herein disclosed principles. The features and advantages of the disclosure can be realized and obtained by means of the instruments and combinations particularly pointed out in the appended claims. These and other features of the disclosure will become more fully apparent from the following description and appended claims, or can be learned by the practice of the principles set forth herein.

Commonly used downhole fluid flow sensors are disposed in a one-dimensional manner within a fluid channel. For example, sensors are disposed in a single line, across the diameter of the channel, or disposed around or embedded in the side of the fluidic channel Additionally, sensors can be spread out over large distances resulting in non-concurrent measurements of the flow within the fluidic channel Such methods provide only a small amount of information regarding the fluid parameters. Failure to obtain information at all points throughout the wellbore can cause errors in calculations relating to flowrate, phase yield, and various other measurements relating to fluid flow which are critical to the stability of the fluidic channel.

Disclosed herein is a sensor arrangement for providing measurements relating to a multi-dimensional area. The multi-dimensional measurement system can provide data for all points throughout a cross-sectional area of the fluidic channel. As such, the measurement device described herein provides a sensor arrangement which allows for a significantly larger amount of data to be obtained.

Specifically, the present disclosure is drawn to a system, method, and apparatus for measuring fluid flow parameters within a fluidic channel. The system and method can use an apparatus such as a hydrodynamic measurement device comprising a plurality of sensors operable to provide flow parameter data throughout the cross-sectional area of the fluidic channel Measurement devices as described herein can be disposed within any fluidic channel including, but not limited to, a pipe, a conduit, a wellbore, and the like. The measurement device described herein can include at least a central body, one or more movable arms, and a plurality of sensors disposed throughout the central body and along the length of the one or more movable arms. The movable arms can be controlled via an actuator to expand out from, and contract towards, the central body of the device. Additionally, the measurement device disclosed herein can be hydro-dynamically designed in order to reduce disturbances within the fluid flow both in the fluidic channel and around the measurement device. In at least one example, the plurality of sensors disposed throughout the measurement device can be arranged such that the sensors are parallel to the flow of the fluidic channel.

The term “sensor” as used herein refers to any device operable to measure and transmit information regarding the immediate surroundings. For example, sensors used in accordance with this disclosure can be operable to detect one or more parameters of a fluid flow including, but not limited to, a fluid flow rate, fluid velocity, fluid level, fluid phase or ID (oil/water/gas), fluid density, pressure within the fluidic channel, and the like.

The term “actuator” as used herein refers to any device configured to modify the behavior of the device, or the behavior of other devices, in response to receiving a command signal.

FIGS. 1A and 1B illustrate exemplary wellbore environments in which the disclosed hydrodynamic measurement device can be used. For example, FIG. 1A illustrates a diagrammatic view of an exemplary logging while drilling (LWD) and/or measurement while drilling (MWD) wellbore operating environment 100 in which the measurement device can be implemented. As depicted in FIG. 1A, a drilling platform 102 is equipped with a derrick 104 that supports a hoist 106 for raising and lowering a drill string 108. The hoist 106 suspends a top drive 110 suitable for rotating the drill string 108 and lowering the drill string 108 through the well head 112. Connected to the lower end of the drill string 106 is a drill bit 114. As the drill bit 114 rotates, the drill bit 114 creates a wellbore 116 that can pass through various subterranean formations 120. The wellbore 116 can be formed according to a desired well plan having one or more vertical, curved, and/or horizontal portions extending through one or more subterranean formations 120. The complexity of well construction leads to challenges in determining the amount and phase of the fluid flowing through the wellbore. A pump 122 circulates drilling fluid through a supply pipe 124 to top drive 110, down through the interior of drill string 108, through orifices in drill bit 114, back to the surface via the annulus around drill string 108, and into a retention pit 126. The drilling fluid transports cuttings from the wellbore 116 into the pit 126 and aids in maintaining the integrity of the wellbore 116. Various materials can be used for drilling fluid, including oil-based fluids and water-based fluids.

As depicted in FIG. 1A, logging tools 134 can be integrated into the bottom-hole assembly 130 near the drill bit 114. As the drill bit 114 extends the wellbore 116 through the subterranean formations 120, logging tools 134 collect measurements relating to the various formation properties as well as the orientation of the tool and various other drilling conditions. The bottom hole assembly 130 can include one or more logging tools 134. In at least one example, one of the logging tools 134 of the bottom hole assembly 130 can include a measurement device 200 as described herein. Further details of the measurement device 200 are provided with respect to FIGS. 2A-2G. The bottom-hole assembly 130 may also include a telemetry sub 132 to transfer measurement data to a surface receiver 128 and to receive commands from the surface. In some example, the telemetry sub 132 communicates with a surface receiver 128 using mud pulse telemetry. In other cases, the telemetry sub 132 does not communicate with the surface, but rather stores logging data for later retrieval at a logging facility 138 on the surface when the logging assembly is recovered. Notably, one or more of the bottom-hole assembly 130, the logging tools 134, and the telemetry sub 132 may also operate using a non-conductive cable (for example, slickline, etc.) with a local power supply, such as batteries and the like. When employing non-conductive cable, communication may be supported using, for example, wireless protocols (for example, EM, acoustic, etc.) and/or measurements and logging data may be stored in local memory for subsequent retrieval at the surface logging facility 138, as is appreciated by those skilled in the art.

Each of the logging tools 134 may include a plurality of tool components, spaced apart from each other, and communicatively coupled with one or more wires. Logging tools 134 may include measurement devices, such as the one shown in FIG. 2A, in order to gather fluid flow parameter data. The telemetry sub 132 may include one or more of wireless telemetry or logging capabilities to collect and/or transmit information indicative of received logging data to operators on the surface or for later access and data processing for the evaluation of fluid flow within the wellbore.

The logging tools 134 may also include one or more computing devices 136 communicatively coupled with one or more of the plurality of tool components. The computing device 136 may be configured to control or monitor the performance of the tools 134, process logging data, and/or carry out the methods of the present disclosure. In at least one example, the computing device 136 can be operable to receive a signal to control one or more of the plurality of tool components.

In some examples, one or more of the logging tools 134 may communicate with a surface receiver 128, such as a wired drill pipe. In other cases, the one or more of the logging tools 134 may communicate with a surface receiver 128 by wireless signal transmission including, but not limited to, pressure wave transmission (such as mud pulse and continuous wave telemetry), acoustic energy transmission, and electromagnetic wave transmission. In at least some cases, one or more of the logging tools 134 may receive electrical power from a wire that extends to the surface, including wires extending through a wired drill pipe. In at least some instances the methods and techniques of the present disclosure may be performed by a computing device (not shown) on the surface. In some examples, the computing device may be included in surface receiver 128. For example, surface receiver 128 of wellbore operating environment 100 may include one or more of wireless telemetry, processor circuitry, or memory facilities, such as to support substantially real-time processing of data received from one or more of the logging tools 134. In some examples, data is processed at some time subsequent to its collection, wherein the data may be stored on the surface at surface receiver 128, stored downhole in telemetry sub 132, or both, until it is retrieved for processing. In an alternative example, the telemetry sub 132 can include a computing device operable to perform preprocessing of the data downhole. In yet another embodiment, the telemetry sub 132 can include a computing device downhole operable to perform preprocessing of the data, which can then be further processed at the surface.

While FIG. 1A indicates that the wellbore is in the drilling stage, the hydrodynamic measurement device described herein can be used at any stage throughout the life of a wellbore. For example, the measurement device can be lowered into a wellbore after drilling is completed, the measurement device can be lowered from a tractor using a logging string, coiled tubing, electric line, slick line, or any other suitable means of lowering a tool into a wellbore. Additionally, the hydrodynamic measurement device 200 disclosed herein can be used throughout the production period of a wellbore in order to provide up-to-date information regarding the fluid phase, flow rate, and other relevant properties throughout the production process.

For example, FIG. 1B illustrates a diagrammatic view of a conveyance logging wellbore environment 150 in which the measurement device disclosed herein may be implemented. As depicted in FIG. 1B, a hoist 156 may be included as a portion of a platform 152, such as that coupled to derrick 154, and used with a conveyance 164 to raise or lower equipment such as logging tool 158 into or out of a borehole surrounded by formation 162. The logging tool 158 can include a measurement device 200 as described herein, additional details of the measurement device 200 are provided with respect to FIGS. 2A-2G. In at least one example, the conveyance 164 may provide a communicative coupling between the logging tool 158 and a logging facility 168 at the surface. The conveyance 164 may include one or more wires, slicklines, cables, or the like, as well as tubular conveyances such as coiled tubing, joint tubing, or other tubulars, and may include a downhole tractor. Additionally, power can be supplied via the conveyance 164 to meet the power requirements of the logging tool. In the alternative, logging tool 158 can include a local power supply, such as batteries, downhole generator and the like. As described above, when employing non-conductive cable, coiled tubing, pipe string, or downhole tractor, communication may be supported using, for example, wireless protocols (such as EM, acoustic, etc.), and/or measurements and logging data may be stored in local memory for subsequent retrieval. Additional devices can be disposed downhole along with the logging tool including, but not limited reservoir measuring devices. Direct measurements of reservoir properties and other fluid and reservoir characteristics can be used to improve the analysis described herein. Such measuring device can include, but are not limited to, a borehole sampler.

The logging facility 168 may include a computing device 166 capable of carrying out the methods and techniques of the present disclosure, including collecting and analyzing data gathered from the measurement device. In this manner, information regarding the fluid flow parameters may be obtained by the measurement device (logging tool 158) and processed by a computing device, such as computing device 166. In some examples, computing device 166 can be equipped to process the received information in substantially real-time, while in other examples, computing device 166 can be equipped to store the received information for processing at a later time. The computing device 166 can be, for example, a computing system as described in more detail with respect to FIGS. 4 and 5. In an alternative example, the logging tool 158 can include a computing device 166 operable to process the logging data obtained downhole. As described above, in at least one example a portion of processing may occur via a computing device 166 downhole and additional computing can be performed on a computing device 166 on the surface.

Modifications, additions, or omissions may be made to FIGS. 1A and 1B without departing from the spirit and scope of the present disclosure. For example, FIGS. 1A and 1B depict components of the wellbore operating environments in a particular configuration. However, any suitable configuration of components may be used. Furthermore, fewer components, or additional components beyond those illustrated, may be included in the wellbore operating environment without departing from the spirit and scope of the present disclosure. It should be noted that while FIGS. 1A and 1B generally depict a land-based operation, those skilled in the art would readily recognize that the principles described herein are equally applicable to operations that employ floating or sea-based platforms and rigs or sub-sea operations, without departing from the scope of the disclosure. Also, even though FIGS. 1A and 1B depict a vertical wellbore, the present disclosure is equally well-suited for use in wellbores having other orientations, including horizontal wellbores, slanted wellbores, multilateral wellbores or the like.

As stated above, the logging tools 134,158 described in FIGS. 1A and 1B can include a measurement device 200. An exemplary measurement device, and various features thereof are illustrated in FIGS. 2A-2G. Specifically, FIG. 2A is a schematic illustrating an exemplary measurement device 200 as described herein. The measurement device 200 can include, at least, a hydro-dynamically designed central body 210, one or more moveable arms 220 operable to be expanded from and retracted to the central body 210, and a plurality of sensors 230 disposed throughout the central body and along the one or more arms. The hydrodynamic body is engineered to reduce disturbances in the flow path where the measurements are being made. In at least one example, the movable arms can be coupled with the central body in a rigid alignment, such as through a cog system. In the alternative, the movable arms can be coupled using a non-rigid alignment. The movable arms as described herein are operable to expand radially outward from the central body towards the sidewalls of the fluidic channel 205 formed by tubular 215 in order to increase the measurement area by placing sensors throughout the flow channel FIG. 2B is a schematic illustrating an enlarged view of an exemplary movable arm 220. In at least one example, the movable arm 220 can include contacts 240 at a bend point along the length of the movable arm 220. The movable arms can be designed to fit any desired fluidic channel. In at least one example, the movable arms of the measurement device can expand to provide an outer diameter of about one and eleven-sixteenths inches. The measurement device described herein can provide users with a sensor placement having a known distance from the center of the wellbore. Suitable contacts 240 can include, but are not limited to, rollers, wheels, skids, balls, or any other means capable of reducing friction at the contact point between the moveable arm and the side, or wall, of the fluidic channel. For example, such contacts can assist in the reduction of drag and friction as the measurement device is moved along the fluidic channel. As such, contacts 240 as described herein can allow for more efficient logging due to the increased mobility of the measurement device within the fluidic channel. For example, the moveable arms 220 can be expanded outward from the central body 210 until the contacts 240 abut the sidewall of a fluidic channel; then contacts, such as smooth rollers or wheels, can allow the measurement device to glide along the fluidic channel without significant resistance. The reduction in sticks and pulls created as the measurement device moves throughout the fluidic channel can allow for increased accuracy and repeatability of data collection.

As described above, each of the plurality of movable arms 220 can include a plurality of sensors 230 spaced along the length of the arm. In at least one example the sensors are symmetrically located on each side of the measurement device. FIG. 2C illustrates a cross-sectional view of an exemplary moveable arm having a symmetrical sensor arrangement. In an alternative example the sensors can be placed such that they are not symmetrically located on each side of the measurement device. The placement of the sensors on each of the movable arms can allow for strategic placement of the sensors throughout the fluidic channel can reduce inaccuracies within flow channels having non-standard flow profiles or cross-sectional areas. Each of the plurality of sensors 230 can include a sensor node operable to align the sensor with the fluid flow 250, as shown in FIG. 2D. In at least one example, the sensors can be gimballed or include a mechanism which allows them to align with the flow direction or align parallel with the fluidic channel.

The movable arms 220 described herein can provide for strategic placement of the sensors throughout the fluidic channel. For example, FIG. 2E illustrates a cross-sectional view of the measurement device 200 having the plurality of arms 220 expanded outward from the central body. The placement of the arms can increase the accuracy of flow measurements within fluid channels. While FIG. 2E illustrates each of the plurality of arms 220 extended outwards from the central body the same distance, it should be noted that each of the moveable arms 220 can move independently. As such, each of the plurality of arms 220 can be expanded at various distances from the central body allowing for measurements to be obtained in channels having non-standard flow profiles or cross-sectional areas. Additionally, the plurality of arms 220 do not have to be arranged in a particular manner about the central body 210. For example, a first portion of the plurality of arms, such as those shown in solid lines in FIG. 2E, can be configured to be staggered with respect to a second portion of the plurality of arms, such as those shown in dashed lines, allowing for fluid to flow more dynamically between and around the arms. Such arrangements can allow for multiple sensors to be placed at various points throughout the fluidic flow channel and communicatively coupled with one another in order to obtain an increased flow profile throughout the channel.

As described above, the one or more movable arms can move independently from one another. Additionally, each of the moveable arms can be configured to collect different, specific fluid parameter measurements at each sensor. For example, the sensors in the measurement device can be operable to detect one or more of fluid velocity, fluid density, fluid temperature, optical ID, and spinner. Furthermore, when the movable arms are expanded outward from the central body of the measurement device, the plurality sensors are distributed at various points throughout the cross-sectional area of the fluidic channel. For example, the plurality of sensors can be located at various distances from the center of the fluidic channel, on the central body of the measurement device, and abutting the sidewall of the fluidic channel Such sensor arrangement can provide a thorough, multi-dimensional evaluation 260 of the fluid parameters at all points throughout the fluid channel, as shown in FIG. 2F. The one or more movable arms 220 can be powered, such that they can be controlled via an actuator to expand and contract from the central body 210. In the alternative, the central body 210 can be configured such that grooves are located along the body so that, when in the contracted configuration, the one or more movable arms 220 lay within the grooves, providing a smooth, hydrodynamic surface. Such design can allow for less restricted movement of the measurement device throughout the fluidic channel Where the arms are configured to fold into the central body, the measurement device can be sized such that it can easily pass through the smallest diameter of the fluidic channel when contracted. Such design can allow the same measurement device to be used in fluidic channels of various sizes, allowing the device to be placed at a desired location within the channel and easily removed when in the closed configuration. The ability to adjust the one or more movable 220 arms, and thus the placement of the sensors 230 within the fluidic channel, as the channel changes in cross-sectional area greatly increases the amount of information collectable by the downhole sensors. Such changes allow for the measurement device 200 to be disposed in areas of a fluidic channel 205 which were previously unable to be monitored.

Specifically, the design of the measurement device 200 allowing for the flexible placement of sensors described herein can offer several different methods to analyze collected data. In a method where a full analysis is not necessary only a portion of the plurality of sensors 230 can be used to gather information. For example, the outside sensors, such as those near the side of the fluidic channel 205, can be used. In such a partial analysis, the data gathered would allow for a fluid flow analysis to be performed based on circumferential outer sensors and one inner sensor, similar to the processes used currently. In an alternative example, data can be obtained using only sensors placed such that the data points are in a single line across the diameter of the fluidic channel 205. Such arrangement can be made vertically or in a horizontal plane. In an alternative method, data obtained from all sensors within the measurement device can be used to gather information. Such method can allow for the collection of improved logging data and fluid measurement accuracy.

For example, horizontal wellbores can require that the measurement device 200 be able to curve around or have influences from incoming fluids from the reservoir. Such changes in orientation and shape can prevent traditional measurement devices from reaching certain portions of the wellbore. The presently described measurement device 200 is operable to evaluate sections of the channel where useful data may be obtained. For example, FIGS. 3A-3C illustrate exemplary fluidic channels having flow profiles which would benefit from the use of the measurement device 200 described herein. Specifically, FIG. 3A illustrates a fluidic channel 300 having a plurality of sensors 310 placed therein. Lines 340 and 350 illustrate the oil/gas contact in flow and the water/oil contact in flow, respectively, within the fluidic channel 300. Line 320 illustrates the estimated flow where data was only obtained from a single line along the diameter of the fluidic channel 300. In the alternative, line 330 illustrates the estimated flow where data was obtained using only circumferential data. As illustrated, sensor placement can have a significant effect on the resulting fluid flow analysis. As indicated in the examples, when data is only retrieved from a small area it can fail to provide a true indication of the flow data. A measurement device 200, as disclosed herein, which provides sensors throughout the entire cross-sectional area of the wellbore can provide a multi-dimensional analysis of the wellbore. Such device provides significantly more accurate data regarding fluid flow parameters. Specifically, the disclosed measurement device 200 can include sensors on the central body of the device providing data of the whole stream, as well as sensors dispersed throughout the area between the central body and the side of the fluidic channel as illustrated in FIG. 2F. FIGS. 3B and 3C illustrate alternative fluidic channels 360,370, respectively, where the fluid flow patterns 340,350 which would benefit from the measurement device 200.

The measurement device 200 described herein can be used to collect data throughout various points within a wellbore. For example, the measurement device 200 can be deployed downhole in the retracted configuration. When the measurement device 200 reaches a desired measurement location a signal can be sent from a computing device 136,166 to the measurement device 200 to actuate the one or more movable arms 220. Once the one or more movable arms 220 are expanded from the central body 210 of the measurement device 200, the device can begin recording fluid flow data. As described above, the measurement device 200 can include contacts that allow for reduced disturbances as the measurement device 200 moves throughout the fluidic channel 205; as such the measurement device 200 can be used to take measurements throughout several points within the fluidic channel 205. The one or more movable arms 220 of the measurement device 200 allow the device to move through deviated and horizontal wellbores which are curved at one or more points within the fluidic channel 205. Once the desired data collection is complete, a signal can be sent from a computing device 136,166 to retract the one or more movable arms 220 back into the central body 210 of the measurement device 200 and the measurement device 200 can be retracted.

As fluid moves through a fluidic channel, materials and sediments within the fluid can cause buildup along the sides of the channel as well as around items disposed therein, including a measurement device. The buildup can include, for example, an increase of paraffin, mudcake, particulate, sludge, or other debris. In at least one example, devices, sensors, and other downhole components can get debris or sludge built up around the devices, causing inaccuracies in the collected measurements. Unless the devices are cleaned, the measurements obtained via the sensors will not provide the accurate information. Typically, traditional measurement devices are required to be removed from the wellbore once the device or sensors have gathered too much buildup to provide useful data, which can result in delays and significant costs.

In at least one embodiment, the measurement device 200 disclosed herein can be configured to be self-cleaning. For example, the measurement device 200 can be operable to remove buildup from the measurement device 200 while disposed downhole. Specifically, as shown in FIG. 2G, the measurement device 200 can be configured such that when in the contracted configuration the one or more movable arms 220 are disposed within slots 270 formed in the central body 210 of the measurement device 200. In at least one example, the measurement device 200 can include one or more cleaning members 280 coupled with the edge of the slots 270 of the central body 210 such that the arms are contacted by the cleaning members 280 as they pass into the central body 210. Such cleaning members 280 allow the measurement device 200 to clean and remove debris and other build up from the plurality of sensors 230 while disposed within a fluidic channel. The cleaning members 280 can include, but are not limited to, a brush, a scraper, an abrasive, a rubber brush, a squeegee, and any other suitable cleaning device that would not damage the sensors. Such self-cleaning measurement device disclosed herein can provide for increased accuracy, improved measurements, and can significantly increase the useful life span of the plurality of sensors 230.

Both the one or more movable arms 220 and the plurality of sensors 230 can be coupled with a computing device 136,166 operable to measure various fluid parameters. As described above, in at least one embodiment, the plurality of sensors 230 can be coupled with a computing device 136,166 to store the data obtained downhole for later review. In the alternative, the plurality of sensors 230 can be coupled with a computing device 136,166 via wired or wireless communication such that the data can be instantly and continuously reviewed. The computing device 136,166 may include any suitable computer, controller, or data processing apparatus capable of being programmed to carry out the method, system, and apparatus as further described herein. FIGS. 4 and 5 illustrate exemplary computing device embodiments which can be employed to practice the concepts, methods, and techniques disclosed herein. The more appropriate embodiment will be apparent to those of ordinary skill in the art when practicing the present technology. Persons of ordinary skill in the art will also readily appreciate that other system embodiments are possible.

The computing devices 136,166 described in FIGS. 1A and 1B can include the computing devices as shown and described in FIGS. 4 and/or 5. The computing device can be used to store, receive, and analyze data gathered downhole by the measurement device 200, as described above.

Specifically, FIG. 4 illustrates a computing device comprising a system bus computing system architecture 400 wherein the components of the system are in electrical communication with each other using a bus 410. Computing device 400 can include a processing unit (CPU or processor) 420 and a system bus 410 that couples various system components including the system memory 430, such as read only memory (ROM) 440 and random access memory (RAM) 450, to the processor 420. The computing device 400 can include a cache of high-speed memory connected directly with, in close proximity to, or integrated as part of the processor 420. The computing device 400 can copy data from the memory 430 and/or the storage device 460 to the cache 422 for quick access by the processor 420. In this way, the cache 422 can provide a performance boost that avoids processor 420 delays while waiting for data. These and other modules can control or be configured to control the processor 420 to perform various actions. Other system memory 430 may be available for use as well. The memory 430 can include multiple different types of memory with different performance characteristics. It can be appreciated that the disclosure may operate on a computing device 400 with more than one processor 420 or on a group or cluster of computing devices networked together to provide greater processing capability. The processor 420 can include any general purpose processor and a hardware module or software module, such as first module 462, second module 646, and third module 466 stored in storage device 460, configured to control the processor 420 as well as a special-purpose processor where software instructions are incorporated into the actual processor design. The processor 420 may essentially be a completely self-contained computing device, containing multiple cores or processors, a bus, memory controller, cache, etc. A multi-core processor may be symmetric or asymmetric.

The system bus 410 may be any of several types of bus structures including a memory bus or a memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. A basic input/output (BIOS) stored in ROM 440 or the like, may provide the basic routine that helps to transfer information between elements within the computing device 400, such as during start-up. The computing device 400 further includes storage devices 460 or computer-readable storage media such as a hard disk drive, a magnetic disk drive, an optical disk drive, tape drive, solid-state drive, RAM drive, removable storage devices, a redundant array of inexpensive disks (RAID), hybrid storage device, or the like. The storage device 460 can include software modules 462, 464, 466 for controlling the processor 420. The computing device 400 can include other hardware or software modules. The storage device 460 is connected to the system bus 410 by a drive interface. The drives and the associated computer-readable storage devices provide non-volatile storage of computer-readable instructions, data structures, program modules and other data for the computing device 400. In one aspect, a hardware module that performs a particular function includes the software components shorted in a tangible computer-readable storage device in connection with the necessary hardware components, such as the processor 420, bus 410, and so forth, to carry out a particular function. In the alternative, the system can use a processor and computer-readable storage device to store instructions which, when executed by the processor, cause the processor to perform operations, a method or other specific actions.
