Abstract
A system and method for monitoring a device in a well, according to which a sensor is embedded in the device for sensing a condition of the device, and outputting a signal in response to the condition.
Description
- Downhole packers are commonly used in many oilfield applications for the purpose of sealing against the flow of fluid to isolate one or more portions of a wellbore for the purposes of testing, treating, or producing the well. The packers are suspended from a tubing string, or the like, in the wellbore, or in a casing in the wellbore, and are activated, or set, so that one or more packer elements engage the inner surface of the wellbore or casing. In these arrangements, it is desirable to know how the packer elements react to the packer setting operation and, after the packer is installed, how the various downhole conditions affect the packer.
- Accordingly, what is needed is a system and method for monitoring the packer conditions under the above circumstances.
- The drawing is a diagrammatic view of a packer and a monitoring system according to an embodiment of the invention.
- Referring to FIG. 1, a downhole tool is referred to, in general, by the
reference numeral 10 and is shown installed in acasing 12 disposed in a well. The well can be either a cased completion as shown in the drawing or an openhole completion. Thetool 10 is lowered to a predetermined depth in thecasing 12 as part of a workstring, or the like, (not shown) which often includes other tools used to perform various oil recovery and completion operations. Since thetool 10 is conventional, it will not be described in detail. - The
tool 10 includes a packer that consists of anannular packer element 14 and anannular slip 16 located downstream and slightly spaced from thepacker element 14. Thepacker element 14 is located at a predetermined axial location in thecasing 12 and is set, or activated, in a conventional manner which causes it to engage the inner surface of thecasing 12 to seal against the flow of fluids and thus permit the isolation of certain zones in the well. Also, theslip 16 is set, or activated, so as to “bite” into the inner surface of thecasing 12 to anchor the packer to thecasing 12. Since both thepacker element 14 and theslip 16 are conventional, they will not be described in further detail. - A plurality of
sensors 20, four of which are shown in the drawing, are embedded in thepacker element 14. If thepacker element 14 is injection molded, thesensors 20 can be formed into thepacker element 14 by suspending thesensors 20 in a packer element mold with a mechanical holding device, such as a small diameter rod, or wire, which can be withdrawn after the mold is filled with an elastomeric material, but before the elastomeric material has set. If thepacker element 14 is formed by an elastomeric component, such as is the case with inflatable packer elements which are formed in a “lay-up” process, thesensors 20 can be placed into the layered-up structure at the appropriate depth between layers as the construction process progresses. - As shown in the drawing, the
sensors 20 can be placed at various locations in thepacker element 14 and can be both axially spaced and radially spaced relative to thepacker element 14. - The
sensors 20 can be fabricated according to one of several high temperature fabrication processes similar to those used in fabricating integrated circuits. For example, a conventional insulated, bulk, complementary metal-oxide-silicon process, using silicon-on-insulator fabrication technologies, can be used. Also, the embeddedsensors 20 and their associated circuits can be constructed using known silicon-on-sapphire fabrications processes. - The
sensors 20 can be designed to sense one or more of several parameters, or conditions, associated with thepacker element 14, including, but not limited to, pressure at different areas in thepacker element 14, local strain in thepacker element 14, shear forces in thepacker element 14, creep in thepacker element 14, chemical conditions in thepacker element 14, as well as any measurement which can be taken more effectively from within thepacker element 14 when compared to measurements taken outside thepacker element 14. - An electronics package is shown, in general, by the
reference numeral 24 and includes atransceiver 26 and appropriate electrical conductors and associated electronics (not shown) electrically connecting thesensors 20 and thetransceiver 26, and extending from thetransceiver 26 to the earth's surface for connection to appropriate electronics, which can include a computing device, and the like (not shown). It is understood that thetransceiver 26 may be, for example, a power and data transceiver, and may contain built-in processing capability that can be used to process the signals from thesensors 20 downhole to determinespecific packer element 14 parameters. Thetransceiver 26 can also be used to transmit processed or raw signals, via a telemetry system, to the earth's surface or to another location within the well. The telemetry system can be, but is not limited to, hardwire, acoustic, EM or mud pulse systems. - In operation, signals from the
sensors 20, which correspond to one or more of the parameters set forth above, are inputted to thetransceiver 26 which processes the signals as discussed above and outputs the signals, or corresponding signals, to the above-mentioned computing device and its associated electronics at the earth's surface. The computing device can then initiate corrective measures to compensate for any predetermined deviation from a standard value set for the particular parameter. - It is understood that several variations may be made in the foregoing without departing from the scope of the invention. For example, the present invention is not limited to sensing one or more or the above-specified conditions, or parameters, but is equally applicable to other parameters consistent with the operation of the packer. Also, the sensors can be embedded in other downhole components utilized in subsurface oil and gas recovery operations, including, but not limited to, packer slips, bridge plugs, etc. Further, the number of packer elements, slips, and sensors can be varied within the scope of the invention. Also, it is understood that spatial references, such as “axially”, “radially”, “downstream”, etc. are for the purpose of illustration only and do not limit the specific spatial orientation or location of the components described above.
- Although only a few exemplary embodiments of this invention have been described in detail above, those skilled in the art will readily appreciate that many other modifications are possible in the exemplary embodiments without materially departing from the novel teachings and advantages of this invention. Accordingly, all such modifications are intended to be included within the scope of this invention as defined in the following claims.
