Physical media can be used to record information. For example, physical media can include a chart, a graph and/or a table that are used to record information. Example information can include measurements of one or more parameters. In some examples, measurements are automatically recorded to the physical media by a recording device. In some examples, measurements are manually recorded by a human operator.
Such physical media can be located at sites, such as well-sites. In some instances, human operators periodically visit a site to collect physical media, and install new physical media for continued recording of information. In some instances, the human operator manually records information that is already recorded on physical media without removing and replacing the physical media. In some cases, the manually recorded information is the human operator's estimate and/or is an estimated average of the information actually recorded on the physical media.

Like reference symbols in the various drawings indicate like elements.
Implementations of the present disclosure are generally directed to generating digital data from physical media that provides information recorded at a well-site. More specifically, implementations of the present disclosure process one or more images of physical media to generate digital data corresponding to information recorded on the physical media. In some examples, the physical media includes a chart that is used to record measurements of one or more parameters. In some examples, measurements are automatically recorded by a recording device. In some examples, measurements are manually recorded.
In some implementations, an operator uses a device to generate the one or more images as one or more machine-readable files, respectively. In some examples, the one or more images are provided to a back-end service that processes the images to generate the digital data. In some examples, the physical media is electronically recreated to provide one or more representations of the digital data. Example representations can include charts, graphs, tables, text and the like.
In some implementations, the one or more machine-readable files are archived in a file library. In some examples, the one or more machine-readable files are archived for use in a subsequent audit. For example, a particular well-site can be audited, which auditing can include review of content captured in the one or more machine-readable files. In some examples, an image file can be converted to another file format. For example, the image file can be converted to a portable document format (PDF) for archiving.
Implementations of the present disclosure will be discussed in further detail with reference to an example context. The example context includes oil and gas well-sites. It is appreciated, however, that implementations of the present disclosure can be realized in other appropriate contexts, e.g., a chemical plant, a fertilizer plant, tank batteries (located away from a site), above-ground appurtenances (pipelines) and/or intermediate sites. An example intermediate site can include a central delivery point that can be located between a site and a refinery, for example. Within the example context, implementations of the present disclosure are discussed in further detail with reference to an example sub-context. The example sub-context includes a production well-site. It is appreciated, however, that implementations of the present disclosure can be realized in other appropriate sub-contexts, e.g., an exploration well-site, a configuration well-site, an injection well-site, an observation well-site, and a drilling well-site.
In the example context and sub-context, well-sites can be located in natural resource plays. A natural resource play can be associated with oil and/or natural gas. In general, a natural resource play includes an extent of a petroleum-bearing formation, and/or activities associated with petroleum development in a region. An example geographical region can include southwestern Texas in the United States, and an example natural resource play includes the Eagle Ford Shale Play.
The computing devices 102, 104 are associated with respective users 112, 114. In some examples, the computing devices 102, 104 can each include various forms of a processing device including, but not limited to, a desktop computer, a laptop computer, a tablet computer, a wearable computer, a handheld computer, a personal digital assistant (PDA), a cellular telephone, a network appliance, a smart phone, an enhanced general packet radio service (EGPRS) mobile phone, or an appropriate combination of any two or more of these example data processing devices or other data processing devices. The computing systems 108 can each include a computing device 108a and computer-readable memory provided as a persistent storage device 108b, and can represent various forms of server systems including, but not limited to a web server, an application server, a proxy server, a network server, or a server farm.
In some implementations, and as discussed in further detail herein, site data (e.g., oil data and/or gas data) can be communicated from one or more of the play networks 106 to the computing systems 108 over the network 110. In some examples, each play network 106 can be provided as a regional network. For example, a play network can be associated with one or more plays within a geographical region. In some examples, each play network 106 includes one or more sub-networks. As discussed in further detail herein, example sub-networks can include a low power data sub-network, e.g., a low power machine-to-machine data network (also referred to as a smart data network and/or an intelligent data network, one or more wireless sub-networks, and mesh sub-networks, e.g., 900 Mhz.
In some examples, the computing systems 108 store the well data and/or process the well data to provide auxiliary data. In some examples, the well data and/or the auxiliary data are communicated over the play network(s) 106 and the network 110 to the computing devices 102, 104 for display thereon. In some examples, user input to the computing devices 102, 104 can be communicated to the computing systems 108 over the network 110.
In general, monitoring of well sites can include oil well monitoring and natural gas well monitoring (e.g., pressure(s), temperature(s), flow rate(s)), compressor monitoring (e.g., pressure, temperature), flow measurement (e.g., flow rate), custody transfer, tank level monitoring, hazardous gas detection, remote shut-in, water monitoring, cathodic protection sensing, asset tracking, water monitoring, access monitoring, and valve monitoring. In some examples, monitoring can include monitoring the presence and concentration of fluids (e.g., gases, liquids). In some examples, control capabilities can be provided, such as remote valve control, remote start/stop capabilities, remote access control.
The example of
Well data and/or control commands can be provided to/from the well site 202 through an access point 216. More particularly, information can be transmitted between the access point 216, the sensor system 210, and/or the communication device 214 based on LP. In some examples, LP provides communication using a globally certified, license free spectrum (e.g., 2.4 GHz). In some examples, the access point 216 provides a radial coverage that enables the access point 216 to communicate with numerous well sites, such as the well site 202. In some examples, the access point 216 further communicates with the network 110 using cellular, satellite, mesh, point-to-point, point-to-multipoint radios, and/or terrestrial or wired communication.
In the depicted example, the access point 216 is mounted on a tower 220. In some examples, the tower 220 can include an existing telecommunications or other tower. In some examples, an existing tower can support multiple functionalities. In this manner, erection of a tower specific to one or more well sites is not required. In some examples, one or more dedicated towers could be erected.
In the depicted example, the well sites 204, 206 include respective wellheads 205, 207, and respective sensor systems 210 (discussed above). Although a single sensor system 210 is depicted for each well site 204, 206, it is contemplated that a well site can include any appropriate number of sensor systems 210. In some examples, well data and/or control commands can be provided to/from the well sites 202 through a gateway 232. More particularly, information can be transmitted between the gateway 232, and the sensor systems 210 can be wireless communication (e.g., radio frequency (RF)). In some examples, the gateway 232 further communicates with the network 110 using cellular and/or satellite communication.
In accordance with implementations of the present disclosure, well site control and/or data visualization and/or analysis functionality (e.g., hosted in the computing cloud 107 of
In some implementations, the service provider can maintain one or more indices of end-points and well site operators. In some examples, the index can map data received from one or more end-points to computing devices associated with one or more well site operators. In some examples, well site operators can include internal server systems and/or computing devices that can receive well data and/or auxiliary data from the service provider. In some examples, the service provider can receive messages from well sites, the messages can include, for example, well data and an end-point identifier. In some examples, the service provider can route messages and/or auxiliary data generated by the server provider (e.g., analytical data) to the appropriate well site operator or personnel based on the end-point identifier and the index. Similarly, the service provider can route messages (e.g., control messages) from a well site operator to one or more appropriate well sites.
As introduced above, implementations of the present disclosure are directed to generating digital data from physical media that provides information recorded at a well-site. More specifically, implementations of the present disclosure process one or more images of physical media to generate digital data corresponding to information recorded on the physical media. In some examples, the physical media includes a chart that is used to record measurements of one or more parameters. In some examples, measurements are automatically recorded by a recording device. In some examples, measurements are manually recorded. In some implementations, an operator uses a device to generate the one or more images as one or more machine-readable files, respectively. In some examples, the one or more images are provided to a back-end service that processes the images to generate the digital data. In some examples, the physical media is electronically recreated to provide one or more representations of the digital data. Example representations can include charts, graphs, tables, text and the like.
In some examples, a physical medium can be used to record relevant information (data). In the example context, example physical media can include a run-ticket and a chart.
In some examples, a run-ticket can be used to record information related to removal of a fluid from a fluid reservoir. In one example, and as discussed in further detail herein, a run-ticket can be used to record information associated with the removal of oil from an oil tank. In further detail, a run-ticket is provided as a physical medium that can be used in transactions (e.g., buying, selling) associated with crude oil. For example, a run-ticket can record information reflecting a change in ownership and/or custody of an amount of oil, where a run-ticket is prepared for the receiver of the oil and the provider of the oil to record the transaction. In some examples, a run-ticket is manually filled out by on-premise personnel (e.g., a “gauger” as the representative of a receiver (purchaser) of the oil, a “pumper” as the representative of the owner (seller) of the oil). Example information recorded on a run-ticket can include opening gauge (e.g., tank level before oil is removed), closing gauge (e.g., tank level after oil is removed), oil gravity (e.g., API gravity), oil temperature, tank temperature, and bottom sediment and water (BS&W). Example information can further include time and date that the oil was removed, and the name of and/or an identifier associated with each personnel involved in removing the oil. In some examples, a run-ticket can be used as an invoice for oil purchased. Implementations of the present disclosure will be discussed in further detail herein with reference to run-tickets.
In some examples, a chart can be used to record readings provided from one or more sensors. In some examples, each sensor can be responsive to changes in a parameter (e.g., pressure, temperature, barometer) and can generate a signal in response to the parameter (e.g., an electrical signal, a physical signal (movement)). In some examples, a chart recorder can be responsive to one or more signals provided by one or more sensors, and can draw traces on a chart, the traces indicating measurements based on the sensor signals. Example chart recorders can include a strip-chart recorder, which draws traces on a strip chart, a circular chart recorder, which draws traces on a rotating disc-chart (e.g., a Barton chart), and a roll-chart recorder, which draws traces on a round roll chart. Implementations of the present disclosure will be discussed in further detail herein with reference to disc-charts.
In some examples, the well-site 300 includes one or more sensors 320a-320g. In some examples, each sensor 320a-320g can be provided as a single sensor. In some examples, each sensor 320a-320g can be provided as a cluster of sensors, e.g., a plurality of sensors. Example sensors can include fluid sensors, e.g., gas sensors, temperature sensors, and/or pressure sensors. Each sensor 320a-320g is responsive to a condition, and can generate a respective signal based thereon. In some examples, the signals can be communicated through a network, as discussed above with reference to
With continued reference to

In the example of
In accordance with implementations of the present disclosure, on-premise personnel can capture images of the physical media, which images can be processed to provide digital data based on the physical media. For example, personnel 350, 352 can each use an associated computing device 102, 104, respectively. In some examples, and as discussed above with respect to
In accordance with implementations of the present disclosure, an image file can be processed to generate digital data that corresponds to data provided in a physical medium, an image of which is digitally represented in the image file. In the example case of a chart (e.g., the chart 332), the image of the chart can be processed to provide a digital version of the chart and/or to provide a graph that is based on the chart. For example, data recorded as traces in the physical chart can be extracted from the chart and can be digitally recreated as data points that can be provided in a table and/or graphed in a graph. In the example case of a run-ticket (e.g., the run-ticket 340), the image of the run-ticket can be processed to extract information from the run-ticket and to create a data record that includes at least a portion of the information, or all of the information.
In some implementations, an image can be received (e.g., an image file can be received by a back-end system) and can be processed to provide the digital data. In some examples, a type of physical media depicted in the image can be provided. For example, the image file can include metadata that indicates whether a chart is depicted in the image, or whether a run-ticket is depicted in the image. In some examples, the image file can include metadata that indicates a type of chart that is depicted in the image (e.g., a strip chart, a circular chart, a roll-chart). In some examples, the image can be processed to determine whether a chart is depicted in the image and/or a type of chart depicted in the image, or whether a run-ticket is depicted in the image. In some examples, the image can be processed based on the type of physical media that is depicted in the image.
In some implementations, the image file includes metadata that indicates parameters that are associated with the image and/or with the context that the image was captured in. Example metadata can include time data, date data, geo-location data, an identifier associated with the well-site where the image was captured, an identifier associated with a device that was used to capture the image, an identifier associated with a user that captured the image, an identifier associated with a chart recorder and/or chart depicted in the image (in the case where the image depicts a chart). It is appreciated that the image file can include any appropriate metadata that may be relevant to the context within which the image was captured. In some examples, a well-site identifier can be associated with the image. In some examples, the well-site identifier uniquely identifies the well-site. For example, a user that captured the image can manually input a well-site identifier. As another example, location data associated with the image (e.g., GPS data indicating a location, at which an image was captured) can be processed to determine the well-site identifier. For example, the location data can be input to an index of well-site locations, and can be matched to a respective well-site, the well-site identifier of the respective well-site being provided from the index.
In some implementations, a plurality of parsers can be provided, which can be used to process the image. In some examples, each parser is specific to a type of physical media. For example, a first parser can be specific to run-tickets, a second parser can be specific to strip charts, and a third parser can be specific to circular charts. In some examples, a parser is selected based on the type of physical media that is depicted in the image, and the parser is used to provide the digital data from the image. In some examples, parsers can be provided as computer-executable programs that include instructions and/or rules for processing images to provide the digital data.
In some implementations, and as discussed above, the image file can include metadata that indicates parameters that are associated with the image and/or with the context that the image was captured in. For example, the device 410 can provide geo-location data, an identifier associated with the device 410 that can be provided as metadata in the image file. In some examples, the user that captured the image 404 can provide an identifier associated with the user, and an identifier associated with the chart recorder 406 and/or the chart 408 depicted in the image 404 that can be provided as metadata in the image file. For example, the GUI 400 can include user input elements (not shown) that the user can provide input. In some examples, the identifier associated with the user can be provided from credentials that the user may have previously provided to log-into software that provides the GUI 400. In the depicted example, the GUI 400 provides an indicator 420 that can indicate, which well-site the user is currently located at (e.g., Well-Site 1B). In some examples, an identifier that uniquely identifies the well-site provided in the indicator can be provided as metadata with the image file. It is appreciated that the image file can include any appropriate metadata that may be relevant to the context within which the image was captured.
In some implementations, the image file is archived in a file library. In some examples, the image file is archived for use in a subsequent audit. For example, the well-site 300 of
In some implementations, manually entered values can be verified and/or corrected based on digital data provided from an image. For example, personnel can capture images of physical media and can also manually record values that the personnel themselves read from the physical media. For example, a person can view a chart and can estimate an average value (manual value) based on a trace provided in the chart. The average value can be provided to the back-end system (e.g., the person enters the average value into a user interface displayed on a computing device). The image of the physical media can be processed, as discussed herein, and an average value can be computed (computed value) based on the digital data determined from the image (e.g., by the back-end-system). The manual value and the computed value can be compared to determine an accuracy of the manual value, for example. In some examples, if the manual value deviates from the computed value by a threshold degree (e.g., >X %), an alert can be provided (e.g., to the person that recorded the manual value, a supervisor of the person). In this manner, improvements to manual recording of values can be achieved.
Although the example of
In some implementations, example physical media can include a receipt, an invoice and a work order. In some examples, well-site operators can purchase goods and/or services for operation of the well-site. In some examples, images of receipts, invoices and/or work orders can be captured, which include information relevant to the goods and/or services purchased (e.g., type, quantity, cost, date of purchase). As discussed above with respect to run-tickets and charts, images of receipts, invoices and/or work orders can be received and processed to provide digital data therefrom. In some examples, the digital data corresponds to the information captured in the images.
In some implementations, digital data provided from receipts, invoices and/or work orders can be used for auditing purposes. In some implementations, digital data provided from receipts, invoices and/or work orders can be used to provide greater granularity in cost calculations. In some examples, a cost-per-barrel value can be determined for a plurality of well-sites based on, for example, an overall operating cost determined for the plurality of well-sites and a number of barrels (e.g., of oil) produced from the plurality of well-sites. Implementations of the present disclosure enable a relatively more accurate, finer grain calculation of cost-per-barrel. For example, operating costs associated with respective well-sites can be determined, at least in part, based on digital data provided from receipts, invoices and/or work orders that are specific to individual well-sites. That is, implementations of the present disclosure enable relatively minor costs (e.g., tools purchased from a hardware store for maintenance at a particular well-site) to be attributed to specific well-sites (e.g., as opposed to a plurality of well-sites). Consequently, a relatively more accurate cost-per-barrel can be provided on a site-by-site basis. In some examples, this enables more poorly performing well-sites to be identified (e.g., for remediation).
An image filed is received (602). For example, a back-end system (e.g., the computing cloud 107 of
Implementations of the subject matter and the operations described in this specification can be realized in digital electronic circuitry, or in computer software, firmware, or hardware, including the structures disclosed in this specification and their structural equivalents, or in any appropriate combinations thereof. Implementations of the subject matter described in this specification can be realized using one or more computer programs, i.e., one or more modules of computer program instructions, encoded on computer storage medium for execution by, or to control the operation of, data processing apparatus, e.g., one or more processors. In some examples, program instructions can be encoded on an artificially generated propagated signal, e.g., a machine-generated electrical, optical, or electromagnetic signal that is generated to encode information for transmission to suitable receiver apparatus for execution by a data processing apparatus. A computer storage medium can be, or be included in, a computer-readable storage device, a computer-readable storage substrate, a random or serial access memory array or device, or a combination of one or more of them. Moreover, while a computer storage medium is not a propagated signal, a computer storage medium can be a source or destination of computer program instructions encoded in an artificially generated propagated signal. The computer storage medium can also be, or be included in, one or more separate physical components or media (e.g., multiple CDs, disks, or other storage devices).
The operations described in this specification can be implemented as operations performed by a data processing apparatus on data stored on one or more computer-readable storage devices or received from other sources.
The term “data processing apparatus” encompasses all kinds of apparatus, devices, and machines for processing data, including by way of example a programmable processor, a computer, a system on a chip, or multiple ones, or combinations, of the foregoing. In some examples, the data processing apparatus can include special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit). In some examples, the data processing apparatus can also include, in addition to hardware, code that creates an execution environment for the computer program in question, e.g., code that constitutes processor firmware, a protocol stack, a database management system, an operating system, a cross-platform runtime environment, a virtual machine, or a combination of one or more of them. The apparatus and execution environment can realize various different computing model infrastructures, such as web services, distributed computing and grid computing infrastructures.
A computer program (also known as a program, software, software application, script, or code) can be written in any form of programming language, including compiled or interpreted languages, declarative or procedural languages, and it can be deployed in any form, including as a stand-alone program or as a module, component, subroutine, object, or other unit suitable for use in a computing environment. A computer program may, but need not, correspond to a file in a file system. A program can be stored in a portion of a file that holds other programs or data (e.g., one or more scripts stored in a markup language document), in a single file dedicated to the program in question, or in multiple coordinated files (e.g., files that store one or more modules, sub programs, or portions of code). A computer program can be deployed to be executed on one computer or on multiple computers that are located at one site or distributed across multiple sites and interconnected by a communication network.
The processes and logic flows described in this specification can be performed by one or more programmable processors executing one or more computer programs to perform actions by operating on input data and generating output. The processes and logic flows can also be performed by, and apparatus can also be implemented as, special purpose logic circuitry, e.g., an FPGA (field programmable gate array) or an ASIC (application specific integrated circuit).
Processors suitable for the execution of a computer program include, by way of example, both general and special purpose microprocessors, and any one or more processors of any kind of digital computer. Generally, a processor will receive instructions and data from a read only memory or a random access memory or both. Elements of a computer can include a processor for performing actions in accordance with instructions and one or more memory devices for storing instructions and data. Generally, a computer will also include, or be operatively coupled to receive data from or transfer data to, or both, one or more mass storage devices for storing data, e.g., magnetic, magneto optical disks, or optical disks. However, a computer need not have such devices. Moreover, a computer can be embedded in another device, e.g., a mobile telephone, a personal digital assistant (PDA), a mobile audio or video player, a game console, a Global Positioning System (GPS) receiver, or a portable storage device (e.g., a universal serial bus (USB) flash drive), to name just a few. Devices suitable for storing computer program instructions and data include all forms of non-volatile memory, media and memory devices, including by way of example semiconductor memory devices, e.g., EPROM, EEPROM, and flash memory devices; magnetic disks, e.g., internal hard disks or removable disks; magneto optical disks; and CD ROM and DVD-ROM disks. The processor and the memory can be supplemented by, or incorporated in, special purpose logic circuitry.
To provide for interaction with a user, implementations of the subject matter described in this specification can be implemented on a computer having a display device, e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor, for displaying information to the user and a keyboard and a pointing device, e.g., a mouse or a trackball, by which the user can provide input to the computer. Other kinds of devices can be used to provide for interaction with a user as well; for example, feedback provided to the user can be any form of sensory feedback, e.g., visual feedback, auditory feedback, or tactile feedback; and input from the user can be received in any form, including acoustic, speech, or tactile input. In addition, a computer can interact with a user by sending documents to and receiving documents from a device that is used by the user; for example, by sending web pages to a web browser on a user's client device in response to requests received from the web browser.
Implementations of the subject matter described in this specification can be implemented in a computing system that includes a back end component, e.g., as a data server, or that includes a middleware component, e.g., an application server, or that includes a front end component, e.g., a client computer having a graphical user interface or a Web browser through which a user can interact with an implementation of the subject matter described in this specification, or any combination of one or more such back end, middleware, or front end components. The components of the system can be interconnected by any form or medium of digital data communication, e.g., a communication network. Examples of communication networks include a mesh network, a local area network (“LAN”) and a wide area network (“WAN”), an inter-network (e.g., the Internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks).
While this specification contains many specific implementation details, these should not be construed as limitations on the scope of any implementation of the present disclosure or of what may be claimed, but rather as descriptions of features specific to example implementations. Certain features that are described in this specification in the context of separate implementations can also be implemented in combination in a single implementation. Conversely, various features that are described in the context of a single implementation can also be implemented in multiple implementations separately or in any suitable sub-combination. Moreover, although features may be described above as acting in certain combinations and even initially claimed as such, one or more features from a claimed combination can in some cases be excised from the combination, and the claimed combination may be directed to a sub-combination or variation of a sub-combination.
Similarly, while operations are depicted in the drawings in a particular order, this should not be understood as requiring that such operations be performed in the particular order shown or in sequential order, or that all illustrated operations be performed, to achieve desirable results. In certain circumstances, multitasking and parallel processing may be advantageous. Moreover, the separation of various system components in the implementations described above should not be understood as requiring such separation in all implementations, and it should be understood that the described program components and systems can generally be integrated together in a single software product or packaged into multiple software products.
Thus, particular implementations of the subject matter have been described. Other implementations are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In certain implementations, multitasking and parallel processing may be advantageous.
This application claims priority to U.S. Provisional Application Ser. No. 61/953,145, filed on Mar. 14, 2014, which is expressly incorporated herein by reference.
