The invention relates to an apparatus having an integrated flow control device and isolation element provided on a mandrel.
As part of completing a well, various components are provided into a wellbore to perform different tasks. Two such components include flow control devices and packers. Flow control devices control flow between various parts of the well, such as between reservoir(s) and a flow conduit (e.g., production tubing, injection tubing, etc.), or between other portions of the well.
The flow control device and packer are typically provided as separate components on a tool string. For example, as shown in
Providing the flow control devices and packers as separate modules adds to the overall complexity and cost of a tool string. Also, because the flow control device and packer are separate components, the overall length of the tool string is increased, particularly when there are a large number of flow control devices and packers provided on a tool string.
In general, according to an embodiment, an apparatus for use in a well comprises a mandrel, a flow control device provided on the mandrel, and an isolation element provided on the same mandrel to provide isolation between zones of the well.
Other or alternative features will become apparent from the following description, from the drawings, and from the claims.
In the following description, numerous details are set forth to provide an understanding of the present invention. However, it will be understood by those skilled in the art that the present invention may be practiced without these details and that numerous variations or modifications from the described embodiments are possible.
As used here, the terms “above” and “below”; “up” and “down”; “upper” and “lower”; “upwardly” and “downwardly”; and other like terms indicating relative positions above or below a given point or element are used in this description to more clearly describe some embodiments of the invention. However, when applied to equipment and methods for use in wells that are deviated or horizontal, such terms may refer to a left to right or right to left relationship as appropriate.
As depicted in
A “mandrel” refers to an integral support structure, such as a housing or other member, on which various components can be supported, including the flow control device and isolation element. The integral mandrel is distinguished from conventional solutions in which a flow control device and packer are typically provided on separate mandrels that are coupled to each other, such as by a threaded connection, or by some other coupling mechanism.
The other module 204 similarly includes an integrated flow control device 214 and isolation element 216 arranged on a common mandrel 218. The isolation element includes an expandable sealing element 220.
As further depicted in
In alternative embodiments, the control line 308 can be an electrical control line or a fiber optic control line. In these cases, the actuating mechanisms 300, 306 are provided with the appropriate control circuitry to decode electrical signaling or optical signaling.
Furthermore, alternative embodiments may employ more than one control line to address and actuate different functions of the integrated module 202. A combination of hydraulic, electrical, or fiber optic control lines may be used to control an integrated module and provide feedback to the surface. Some of these control lines are shared with and may continue to other integrated modules, for example 204, in the wellbore 100 to minimize the number of control lines going to the surface.
An application where some of the
By integrating multiple functions onto a single mandrel (module), in accordance with some embodiments, more efficient usage of space in a wellbore can be achieved. The integration allows for more compact (shorter) assemblies of components such that shallow zonal isolation can be achieved. Also, integration allows for the sharing of a control line for enhanced efficiency. Moreover, misalignment issues of different components in a tool string can be eliminated or reduced, due to integration of multiple components in one module. Other advantages include a lower probability of leaks due to the elimination of threaded or other connections, reduced number of connections and splices for control lines, and quicker deployment at the job site due to pre-integration.
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 therefrom. It is intended that the appended claims cover such modifications and variations as fall within the true spirit and scope of the invention.
