Description

CONTEXT

This section is intended to provide relevant contextual information to facilitate a better understanding of the various aspects of the described embodiments. Accordingly, it should be understood that these statements are to be read in this light and not as admissions of prior art.

During a multizone completion operation, a tubing string is introduced into a cased wellbore which has been previously perforated and the string is then placed so that production screens are positioned proximate the perforations. As used herein, completion operation refers to the events and equipment necessary to bring a wellbore into production once drilling operations have been concluded. Production can be stimulated by injection of fracturing fluid, acid, solvents, or other chemicals into the perforations. To accomplish this, stimulation operations are performed in portions of the wells to increase a production rate and/or capacity of hydrocarbons from the formation. As used herein, the terms “stimulate” and “stimulation” refer to a treatment performed to restore or enhance the productivity of a well. Stimulation operations include a procedure known as “hydraulic fracturing” wherein fluid is injected into a formation above the fracture pressure of the reservoir formation to create highly conductive flow paths between reservoir and the formation. Other stimulation operations include acidizing, acid-fracing, etc.

Where the wellbore is lined with casing and cement, the stimulation fluids may be conveniently injected into a specific desired stimulation location within a formation by forming openings radially through the casing and cement at the stimulation location. These openings are typically formed by perforating the casing utilizing shaped explosive charges or water jet cutting. The stimulation fluids may then be pumped from the earth's surface, through tubing extending into the casing, and outward into the formation through the perforations.

Where there are multiple desired stimulation locations, sealing devices, such as packers and plugs, are employed to permit each location to be separately stimulated. Each stimulation location within a single formation, or within multiple formations, intersected by a well can be isolated from other stimulation locations, and thus allowing the stimulation operation to be tailored for the specific stimulation location (e.g., type of stimulation fluid, stimulation fluid pressure, and flow rate into the formation). The casing and cement lining the wellbore, along with the sealing devices, prevent loss of stimulation fluids from each desired stimulation location during the stimulation operation. In this manner, an operator performing the stimulation operation can be assured that all of the stimulation fluids intended to be injected into a formation at a desired location are indeed entering the formation at that location.

DETAILED DESCRIPTION

FIG. 1 shows an elevation view of a well system 110 including a screen section 124 and a power control device 140, in accordance with one or more embodiments. As shown, a wellbore 112 intersects a subterranean earth formation 120. The wellbore 112 has a vertical section 114, which is at least partially cemented with a casing string 116, and a horizontal section 118, which can be an open-hole section of the wellbore 112. Other wellbore configurations may also be suitable.

Positioned within the wellbore 112 and extending from the surface is a tubing string 122, which provides a conduit for formation fluids to travel from the formation 120 to the surface and for stimulation fluids to travel from the surface to the formation 120. The tubing string 122 includes a screen section 124, each of which is positioned between a pair of annular barriers depicted as packers 126 that provides a fluid seal between the tubing string 122 and the wellbore 112, thereby defining a production intervals 130. The screen section 124 is employed to inject stimulation fluid into the formation or filter particulate matter out of the production fluid stream. A flow control device 132 may also be located in the wellbore 112 and configured to control the flow of fluid entering, flowing through, or exiting a flow path such as the tubing string 122. The tubing string 122 also includes a power control device 140 to provide power to various electronic components, including but not limited to pumps, sensors, actuators, valves, sleeves, and baffles used to stimulate the formation and/or produce formation fluids, as further described herein with respect to FIGS. 2 and 3. Although FIG. 1 shows the power control device 140 positioned in a zone that is not being produced, it should be understood that the power control device 140 may be positioned anywhere along the wellbore 112, including proximate the screen section 124. In a preferred embodiment, a plurality of power control devices 140 are deployed in the wellbore 112.

The power control device 140 may include a telemetry device 152 that receives data provided by various sensors located in the wellbore 112, and transmits the data to a surface control unit 128. The sensors may include a receiver responsive to electromagnetic radiation for measuring formation resistivity, a gamma ray device for measuring formation gamma ray intensity, devices for measuring the inclination and azimuth of the tubing string 122, pressure sensors for measuring fluid pressure, temperature sensors for measuring wellbore temperature, distributed optical sensors, a flow meter for measuring flow rates, geophones or accelerometers for taking seismic, microseismic, or vibration measurements, a device for measuring fluid composition, etc.

Data may also be provided by the surface control unit 128, received by the telemetry device 152, and transmitted to the various electronic devices located in the wellbore 112 to perform functions, such as actuating a valve. The surface control unit 128 can include a computer system for processing and storing the measurements gathered by the sensors located in the wellbore 112. Among other things, the computer system may include a non-transitory computer-readable medium (e.g., a hard-disk drive and/or memory) capable of executing instructions to perform such tasks. In addition to collecting and processing measurements, the computer system may be capable of controlling completion, stimulation, and production operations including but not limited to as installation of the packers 126, acidizing, gravel packing, or hydraulic fracturing. The surface control unit 128 may further include a user interface (not shown), e.g., a monitor or printer, which displays the measurements and allows an operator to monitor the completion, stimulation and production operations.

FIG. 2 shows a block diagram view of a power control device 240 electrically coupled to one or more electronic device(s) 260, in accordance with one or more embodiments. The power control device 240 includes a battery 242, a turbine generator 244, a processor 246, an information storage device 248, a power sensor 250, a telemetry device 252, and a switch 254. The power control device 240 supplies power to the electronic devices 260 located in a wellbore. The battery 242 and the turbine generator 244 may also be in electrical communication with and supply power to any one or a combination of the processor 246, the storage device 248, the power sensor 250, and the telemetry device 252 as is needed to operate these components downhole. The electronic devices 260 are not supplied power via an umbilical to the surface, and thus, the power control device 240 is the only source of electric power downhole for these devices. For example, the electronic devices 260 may be installed in a lateral wellbore where an umbilical to supply power cannot be installed. Although the components 242-254 are depicted as being integral with or included in the power control device 240, it should be appreciated that any of these may be separate components in communication with the power control device 240.

The battery 242 includes any suitable device comprising one or more cells connected together to furnish electric current to the electronic devices 260. The battery 242 may only be one or more primary batteries, including but not limited to a lithium primary battery, a lithium thionyl chloride battery, a lithium sulfuryl chloride battery, a lithium ion battery, a molten salt battery, or a solid state battery. As used herein, a primary battery refers to a non-rechargeable battery, whereas a secondary battery refers to a rechargeable battery. The battery 242 may supply power to the electronic devices 260 during the initial completion and stimulation operations when there is insufficient fluid flow to generate enough power from the turbine generator 244 to power the electronic devices 260. The battery 242 may also supply power to the electronic devices 260 in conjunction with the turbine generator 244 as further described herein.

The turbine generator 244 includes any suitable device that converts mechanical energy from fluid flowing through a flow path (e.g., the tubing string 112 or the screen section 124 of FIG. 1) to electrical energy. The turbine generator 244 includes a turbine (not shown) in fluid communication with the flow path to rotate the turbine. The turbine generator 244 generates an electric current as fluid passes through or across the turbine coupled to a rotor that rotates within a stator to induce the electric current. As a non-limiting example, the turbine generator 244 may include a rotating magnet, called the rotor, which turns within a stationary set of conductors wound in coils, called the stator, to induce the electric current. The turbine generator 244 may also be a dynamo that produces direct current (including a brushed turbine generator) or an alternator that produces an alternating current (including a brushless turbine generator).

When the flow path in communication with the turbine generator 244 is closed, the battery 242 supplies power to the electronic devices 260 located in the wellbore 112 of FIG. 1. For example, the flow path in communication with the turbine generator 244 can be closed when the packers 126 of FIG. 1 are being set in the wellbore 112 of FIG. 1 as hydrostatic pressure is used to expand the packers 126. After the flow path in communication with the turbine generator 244 is opened, the turbine generator 244 can provide power to the electronic devices 260. For example, the turbine generator 244 may supply power to the electronic devices 260 during stimulation operations that inject fluid into the formation as fluid flows through the flow path in communication with the turbine generator 244. The turbine generator 244 may also supply power to the electronic devices 260 during production of formation fluid as fluid flows through the flow path in communication with the turbine generator 244.

The electronic devices 260 are locatable in a wellbore (e.g., the wellbore 112 of FIG. 1) to perform completion and/or production operations in the well and are electrically coupled to the battery 242 as well as the turbine generator 244. An electronic device 260 may include devices such as a sensor used to monitor the completion and/or production operations conducted in the well. The sensor can include one or more devices configured to measure a downhole parameter, including but not limited to pressure, flow rate, tool position, tool orientation, valve position, vibration, fluid composition, tool passage, wellbore temperature, resistivity, or a combination thereof. For example, the sensor may include at least one of a pressure gauge, flow meter, accelerometer, geophone, gravitometer, proximity sensor, spectrometer, temperature sensor, magnetometer, electromagnetic receiver, etc. The electronic devices 260 may also include the processor 246, the storage device 248, the power sensor 250, and the telemetry device 252 so that these components of the power control device 240 may receive power as well.

As another example, the electronic devices 260 may include a valve, a pump, or an actuator. The valve can be electrically actuated to control fluid flow through the tubing string 112 of FIG. 1. The flow control devices 132 may include a valve (e.g., a solenoid valve) to control fluid entering, flowing through, or exiting the tubing string 112. The pump may be an electric submersible pumps (ESPs) used to pump formation fluid into the tubing string 112. The actuator can be used to actuate downhole tools located in the well. For example, the actuator may be used to set latches, release baffles, or shift sleeves and can include a solenoid, magnetorestrictive device, electric motor, piezoelectric device, pyrotechnic device, an electromagnetic transducer, or any other suitable device configured to convert electrical energy into mechanical energy.

The processor 246 is used to monitor a power condition associated with the power supplies, the battery 242 and the turbine generator 244, to determine whether the battery 242, the turbine generator 244, or both is/are to be used to supply power to the electronic devices 260. As used herein, the term processor is intended to include devices such as a field programmable gate array (FPGA), peripheral interface controller (PIC), advanced RISC machine (ARM), digital signal processor (DSP), microcontroller unit (MCU), microprocessor unit (MPU), and AVR processors. The processor 246 is configured to determine if the power condition is satisfied to allow the turbine generator 244 to power the electronic devices 260, and the processor 246 is configured to power the electronic devices 260 only with the battery 242 if the power condition is not satisfied. The processor 246 may control a switch 254 (e.g., a transistor, a selector, multiplexer, or multiswitch) coupled to the battery 242 and the turbine generator 244 to select which power supply or both power supplies power(s) the electronic devices 260. The switch 254 may also be operable to select which electronic devices 260 receive power from the power supplies to regulate the electrical load on the battery 242 and/or the turbine generator 244.

The power condition can include, but is not limited to, any one or combination of a power threshold, time duration, pressure, flow rate, and temperature. For example, the power condition can be whether the power output of the battery 242 and/or the turbine generator 244 satisfies the power threshold, which can include a threshold voltage, electric current, or electric power. The power condition can also be whether the electronic devices 260 have been powered by the battery 242 for a certain duration of time or whether a condition in the wellbore is satisfied to indicate that the turbine generator 244 can provide sufficient power to the electronic devices 260 (e.g., a fluid flow rate, temperature, or pressure in the fluid flow path to power the turbine generator 244).

The information storage device 248 may include a non-transitory storage medium to electronically store information or data received from sensors located in the wellbore (such as the power sensor 250 or the electronic devices 260). The non-transitory storage medium may include ROM, EPROM, EEPROM, flash memory, RAM, a hard drive, a solid state disk, an optical disk, or a combination thereof. The control and processing of the power control device 240 is performed with the use of a computer program stored on the storage device 248.

The power sensor 250 is in communication with the processor 246 to provide measurements to monitor the power condition of any one or combination of the battery 242 and the turbine generator 244. The power sensor 250 can include one or more devices configured to measure a parameter associated with the power condition, including but not limited to voltage, electric current, electric power, pressure, flow rate, temperature, or a combination thereof. The power sensor 250 may include but is not limited to a volt meter, an ammeter, a watt meter, a pressure gauge, a flow meter, a temperature sensor, or a combination thereof.

The telemetry device 252 may be used to receive or transmit data to various devices of the well system 110. The measurements from the power sensor 250 or the power condition may be transmitted to a surface control unit (e.g., a surface control unit 128 of FIG. 1) and output to a suitable medium, such as a display, tablet, or printer. The surface control unit 128 may also transmit commands to the telemetry device 252 to control which power supply (the battery 242, the turbine generator 244, or both) provides power to the electronic devices 260. The telemetry device 252 may enable data to be output and/or received in real-time, pseudo real-time, and/or at a later time or date. The telemetry device 252 may include a telemetry system to communicate with the surface control unit 128, such as an acoustic pulse telemetry transceiver. The telemetry device 252 may include a direct cable connection device to enable a cable to be input into the telemetry device 252 to transmit and/or upload data. The telemetry device 252 may also include a wireless communication device, in which the wireless communication device may include, but is not limited to, an inductive coupling unit, acoustic telemetry through the tubing string (112 in FIG. 1), acoustic telemetry through the wellbore fluid, a radio-frequency unit, a radio-frequency identification unit, and/or a suitable wireless communication unit (e.g., ZigBee, Bluetooth, UHF, VHF, Wi-Fi, or the like).

It should be appreciated that other electrical components may be included with the power control device 240, including but not limited to a current rectifier or a voltage regulator. For example, where the turbine generator 244 generates an alternating current, a current rectifier may be used to convert the AC power to DC power for the electronic devices 260. The current rectifier may be a half-wave rectifier, a full-wave rectifier, or any other device suitable to rectify the AC current. As another non-limiting example, a voltage regulator may be used to convert the voltage generated by the turbine generator 244 to the voltage needed by the electronic devices 260. The voltage regulator may be a step-up or step-down voltage regulator including a buck-boost transformer or a buck-boost converter.

FIG. 3 shows a flowchart view of a method 300 of powering electronics in a wellbore during completion and production operations, in accordance with one or more embodiments. At block 302, completion equipment is positioned and installed in a well without an umbilical to the surface to supply power. The completion equipment can include, but is not limited to, the equipment depicted in FIGS. 1 and 2 such as the tubing string 122, screen section 124, packers 126, flow control device 132, power control device 140, and electronic devices 260. In the early stage of the completion, such as before stimulation, the flow path through the tubing string 122 may be blocked in order to aid the stimulation. For example, at block 304, a flow path in communication with the turbine generator 244 is closed during a completion operation, such as setting the packers 126 by diverting the fluid in the tubing string 122 with the flow control device 132 to radially expand the packer 126. With the flow path closed, the turbine generator 244 is unable to generate power for the electronic devices 260. The flow path may also be closed during installation of other completion equipment or during part of the wellbore stimulation.

At block 306, the battery 246 powers the electronic devices 260 during the installation of the completion equipment and while various completion operations are being conducted. A stimulation operation or other completion operations may be performed while the electronic devices 260 are being powered by the battery 242. The stimulation operation may include, but is not limited to, formation cleanup, circulating wellbore fluids, acidization, gravel packing, and/or hydraulic fracturing of the wellbore. The battery 242 can provide power to the processor 246 to use the sensor measurements of the electronic devices 260 to estimate flow diversion, formation parameters, and the robustness of the installation of completion equipment. The battery 242 can provide power for the telemetry device 252 to receive wireless commands and to transmit sensor data to the surface. The telemetry device 252 may transmit data collected by the various sensors of the battery-powered electronic devices 260 to the surface so that completion and stimulation operations can be monitored and optimized. The battery 242 can also provide power to downhole tools including setting latches, releasing baffles, shifting sleeves, and opening valves to perform various completion or stimulation operations.

At block 308, the flow path in communication with the turbine generator 244 may be opened during or after stimulation. For example, the flow path may be opened to allow stimulation fluid to be injected into the formation. The stimulation fluid can include brine, water, drilling fluid, oil, acid (organic or inorganic), or a gel. The flow path may also be open during production to allow formation fluid to travel to the surface. The flow path may be opened in response to receiving a command from the surface, in response to a certain time duration expiring, or in response to one or more of the sensor measurements of the electronic devices 260 indicating that the formation is suitable for production, such as acoustic vibrations or temperature changes that indicate that the stimulation is completed to produce formation fluids. With the flow path open, the turbine generator 244 may produce an electric current, which can power the electronic devices 260. Thus, it should be appreciated that the turbine generator 244 can generate power during either a stimulation operation or production of formation fluids. However, the power generated by the turbine generator 244 can be different depending on the direction of the fluid flow. In a preferred embodiment, the turbine generator 244 produces significantly more power during production than during a stimulation operation, including injecting a stimulation fluid into the formation.

At decision block 310, the processor 246 monitors the power condition using the power sensor 250 to select any one or combination of the power supplies (the battery 242, the turbine generator 244, or both) to provide power to the electronic devices 260. If the power condition is not satisfied, the battery 242 continues to power the electronic devices 260 at block 312. If the power condition is satisfied, the processor 246 allows the turbine generator 244 to power the electronic devices 260 at block 314. The processor 246 may also receive a command from the surface control unit 128 via the telemetry device 252 and the command may indicate any one or combination of the power supplies (the battery 242, the turbine generator 244, or both) that is/are to be used to provide power to the electronic devices 260. Thus, the processor 246 may control any one or combination of the power supplies (the battery 242, the turbine generator 244, or both) that is/are used to provide power to the electronic devices 260 based on the received command or the monitored power condition.

While there may be a short period of time where power is provided by both the battery 242 and the turbine generator 244, shortly after production begins the turbine generator 244 is the only source of electrical power for the electronic devices 260. When the battery 242 is discharged, the turbine generator 244 continues to provide power to the electronic devices 260 without the battery 242.
