Description
- 1. Field of the Invention
- Embodiments of the present invention generally relate to radio frequency identification well delivery systems and methods.
- 2. Description of the Related Art
- The following descriptions and examples are not admitted to be prior art by virtue of their inclusion in this section.
- Radio Frequency Identification (RFID) technology has been used outside of the oilfield industry for a number of years to provide one-way and two-way communication and identification. However, the technology is gaining increased acceptance within the oilfield industry, primarily in surface oilfield applications such as inventory control (e.g., equipment identification) and to an extent in downhole applications to communicate with tools placed downhole. In current applications, RFID technology is deployed using one of the following approaches:
-
- Placing a downhole RFID module in the drill string, tubing, or casing, to identify downhole locations and subsequently conveying a reader to perform an operation at a specific location when the correct ID code is identified.
- Pre-programming a downhole tool that will actuate when an RFID chip is dropped inside the tubing, drill string, or casing.
- The existing approach typically pumps or drops the RFID chips or tags down the tubular. However, this is only possible during specific times and situations. When the well is shut-in, dead, highly deviated or horizontal, an RFID device cannot be dropped down. This is also true for a flowing well (i.e., for a flowing well, dropping an RFID is also not possible or practically feasible). In addition, dropping an RFID device only provides one-way travel down the main bore of a substantially vertical well while pumping an RFID device downhole requires an intervention and interruption of production flow.
- In accordance with one embodiment of a system for communicating with downhole components, the system may comprise one or more RFID devices configured with an identification code (ID code). The system may further include a device conduit extending proximate to the downhole components and a device propulsion system. The device propulsion system may translate the one or more RFID devices proximate to the downhole component to facilitate an exchange of information between the downhole component and the RFID device.
- In accordance with one embodiment of a method for communicating with downhole components, the method may comprise providing a device conduit proximate to the downhole components and propelling an RFID device proximate to the downhole components via the device conduit and a device propulsion system. In addition, the method may further comprise exchanging information between the RFID device and the downhole components.

- Referring generally to
FIG. 1 , in accordance with an exemplary embodiment of the invention, awell system 10 may comprise a wellbore 20 extending from the surface of theearth 40 to aformation 50 containing desirable production fluids, such as hydrocarbons, among other fluids. Although thewell system 10 is shown as a terrestrial surface well, embodiments of the communication system may also be used in sub-sea applications. Portions of thewell bore 20 may be lined withcasing 25, although the use ofcasing 25 is not required. Thewell system 10 may be completed to facilitate production of the desirable fluids to thesurface 40 of the well. The completion may compriseproduction tubing 30 or tubulars andvarious downhole components - The
downhole components well system 10. For example, thedownhole component 33 a may comprise a formation isolation valve (FIV) used to suspend or shut-in a well (i.e., closing off or preventing communication between thesurface 40 andformation 50 via the production tubing 30).Downhole component 33 b may represent an inflow control device (ICD) used to facilitate or control flow between theformation 50 and the interior bore of theproduction tubing 30 via screens,perforations 27, or an openhole section.Downhole component 33 c may represent a sensor configured to measure a well parameter such as flow rate, temperature, pressure, conductivity, water cut, phase composition, or valve actuation position, among other parameters not specifically identified. - The annulus surrounding the
production tubing 30 may sealed with apacker 35, such as a casing packer, swell packer, etc., so that theentire well bore 20 is sealed when thedownhole component 33 a is shut or closed (in cases in whichdownhole component 33 a is an FIV).Packer 35 may comprise one or more pass-throughs for a corresponding number of conduits, such as device conduit 120 a and 120 b. In some embodiments, the device conduits 120 a, 120 b may comprise hydraulic control lines in order to take advantage ofstandard packer 35 pass-through configurations. Although only device conduits 120 a, 120 b are shown, additional conduits such as hydraulic control lines for valve actuation or fiber optics may also be present, among others. -
Device conduits production tubing 30. In some embodiments, device conduits 120 a and 120 b may be run inside ofproduction tubing 30 to facilitate control and communication with various downhole components 33 a-33 c in a flowing well, for example. In still other embodiments, device conduits 120 a and 120 b may be composed of various sections or multiple links and lines. In some cases the links may be created inside of the production tubing 30 walls or extend to the interior bore of the completion. - As shown in this illustrative example, device conduits 120 a and 120 b may be coupled together via a
turnaround sub 130. Theturnaround sub 130 facilitates a continuous loop of device conduits so that anRFID device 90 may be placed into the system at thesurface 40 of the well, flow past the various downhole components 33 a-33 c, and be returned to thesurface 40 of the well. For example, this type of system may be used in cases in which anRFID device 90 exchanges information comprising data from a sensor (such as may be represented bydownhole component 33 c). TheRFID device 90 may comprise a data storage area to store data measured by thesensor 33 c. At thesurface 40, theRFID device 90 may be read by anRFID reader 110 and the data extracted or copied for future use related to well operation or analysis. - The
RFID device 90 may be placed in adevice propulsion system 100 located at thesurface 40 of thewell system 10. Thedevice propulsion system 100 may be coupled to the device conduits 120 a and 120 b. In some cases, thedevice propulsion system 100 may be a pump, configured to circulate fluid through the device conduits 120 a and 120 b. TheRFID device 90 may be configured in the shape of a pill for example, sized small enough to translate within the device conduits 120 a, 120 b andturnaround sub 130, but large enough to allow for the buildup of a pressure differential between the upstream and downstream ends of theRFID device 90. In some embodiments, theRFID device 90 may comprise a seal (not shown) in order to readily facilitate the creation of the pressure differential. The pressure differential may provide the motive force for moving theRFID device 90 through thedevice conduits turnaround sub 130. - The communication system of the exemplary embodiment shown in
FIG. 1 allows for anRFID device 90 to travel in two directions as theRFID device 90 interacts with downhole components 33 a-33 c. AsRFID devices 90 travel via thedevice conduits particular RFID device 90. In some cases, a stored command may also be present in anRFID device 90, such as FIV open, or ICD to 40% flow through, among others, so that actuation of a particular downhole component 33 a-33 c may be achieved without requiring a separate or dedicated communication line to that downhole component. Therefore, exchanging information between anRFID device 90 and a downhole component 33 a-33 c may occur in one direction (i.e., from an RFID device to a downhole component, or from a downhole component to an RFID device) or in two directions (i.e., between an RFID device and a downhole component). - Turning now to
FIG. 2 , this drawing illustrates another embodiment of a communication system configured according to aspects of the present invention. In this drawing, wellsystem 200 may represent a shut-in or closed well. For example,downhole component 33 a may represent an FIV whiledownhole component 33 b may represent an ICD or other completion component. Thiswell system 200 differs from theprevious well system 10 in that only onedevice conduit 120 extends along the completion (represented by production tubing 30).Device conduit 120 may be coupled with a one-way valve 230 such as a check valve, located at some position downhole. In this example, anRFID device 90 may be placed within adevice propulsion system 100 and travel via adevice conduit 120 downhole pastdownhole components RFID device 90 passes these downhole components, thedownhole components RFID device 90 or other command information and perform some operation, such as opening, closing, etc. - The one-
way valve 230 may be configured to allow theRFID device 90 to pass through the valve and exit into the annulus surrounding theproduction tubing 30. As a result, an operation may be able to control and communicate (in this example, primarily in one direction) with a downhole component located below a shut-in point, without having to compromise the sealing integrity of a shut-in device, such as may be the case ifdownhole component 33 a is an FIV. -
FIG. 3A shows a schematic illustration of a representative but non-limiting check valve that may be used for one-way valve 230. As shown in this illustrative example, the one-way valve 230 may exit into an annulus surroundingproduction tubing 30 via avalve exit 235. In some cases, thevalve exit 235 may be replaced with aconduit 320 so that the one-way valve 230 exits into the interior bore of theproduction tubing 30 via a valve exit 325 (seeFIG. 3B ). Although the one-way valve 230 andconduit 320 are shown as separate components, many different configurations of valves and housings may be used. For example, one method may be to integrate theconduit 320 andvalve exit 325 into the housing of the one-way valve 230 or to use other devices and components that facilitate the one-way translation of anRFID device 90 by adevice propulsion system 100. - Referring generally to
FIG. 4 , another illustrative embodiment of a communication system of the present invention may be used in multi-zone and/or horizontal or deviated wells.Multi-zone well system 300 is shown as having awellbore 20 that extends to more than one formation or more than one zone in a single formation (two formations, each with a corresponding zone are shown in this example).Wellbore 20 extends toformations production tubing 30 is segmented by open-hole packers 335 b-335 c so that each of theformations Device conduits Downhole component 333 a may be represented by an FIV whiledownhole components 333 b-333 c may each be represented by ICDs, among other types of downhole components.Downhole components 337 b-337 c may be represented as sensors. As shown in the drawing,device conduits turnaround sub 130. - Within the zone defined by open-
hole packers formation 52, anRFID device 90 may be coded with a specific command fordownhole component 333 b. Alternatively,downhole component 333 b may be configured to recognize a particular ID code to actuate during an exchange of information, such as opening or closing or an intermediate step between opened and closed. Further,downhole component 337 b may exchange data representing the amount of water cut entering into theproduction tubing 30 fromformation 52. If the percentage of water becomes too high, anotherRFID device 90 may be used to close or change the choke setting of thedownhole component 333 b so that production can continue fromformation 54 with less water contamination or without water contamination fromformation 52. In this way, the overall life ofwell system 300 may be extended. - As with previous examples, the
RFID devices 90 may be propelled through thedevice conduits device propulsion system 100 and read at the surface by anRFID device reader 110. If the percentage of water from bothformations downhole component 333 a may be closed, shutting in theentire well system 300 or the choke setting may be changed to reduce the water cut. Theproduction tubing 30 may be sealed with casingpacker 35 to prevent any fluid flow through the annulus. However, even with the well shut in,RFID devices 90 may be circulated through thedevice conduits downhole components sensors - Turning generally to
FIG. 5 , a method for establishing a communication system for a well 500 may be shown by the exemplary flowchart in the drawing. One step of the method may be providing a device conduit proximate todownhole components 510. This may occur when the completion is run or after the well is producing (such as via wireline or coil tubing). The device conduit may comprise a single conduit (for one way translation of an RFID device) or a dual conduit (for two way translation of an RFID device). In some cases, a single conduit may provide two way translation of an RFID device if the distal end of the single device conduit is coupled to a storage area or reservoir so that the propulsion system may push and then pull an RFID device back and forth pass a downhole component. - Another step of the method may be propelling an RFID device proximate to the downhole components via the device conduit and a
device propulsion system 520. In some cases, thedevice propulsion system 520 may be a pump configured to pump fluid through the device conduit. In other cases, the pump may be configured to pump fluid into the device conduit and out from the device conduit. - An additional step of the method may be exchanging information between the RFID device and the
downhole components 530. As with the device propulsion system, the exchange of information may be one way, two way, or a combination of both (e.g., one way with some components and two way with others). For example, the downhole components may be configured to read an ID code from every RFID device but only send sensor data to RFID devices equipped to store the information. A single RFID device may control a single downhole component or may control multiple downhole components. - Elements of the embodiments have been introduced with either the articles “a” or “an.” The articles are intended to mean that there are one or more of the elements. The terms “including” and “having” are intended to be inclusive such that there may be additional elements other than the elements listed. The term “or” when used with a list of at least two elements is intended to mean any element or combination of elements and should not be considered as an exhaustive list.
- While the invention has been disclosed with respect to a limited number of embodiments, those skilled in the art, having the benefit of this disclosure, will appreciate numerous modifications and variations there from. It is intended that the appended claims cover such modifications and variations as fall within the true spirit and scope of the invention.
