Abstract
A downhole tool including a body having a function relevant to a selected environment, an electroactive polymer (EAP) anchor disposed with the body and configured to expand, upon application of an electric signal to the EAP, into loaded contact with a tubular member in which the downhole tool is to be set during use. A method for managing a borehole including running a tool to a selected depth in the borehole, applying an electric signal to the EAP, and anchoring the tool with the EAP. A borehole system including a borehole in a subsurface formation, a string in the borehole, a tool disposed within or as a part of the string.
Description
- In the resource recovery and fluid sequestration industries there is often a need to anchor tools in place for specific operations. The anchors also may at times provide a seal against a tubular in which the anchor is active. In recent times, there has been growing interest in settable and resettable anchors to enhance efficiency in borehole operations by managing several operations on one run. Additional innovations that improve or enhance an operators ability to improve efficiency are always welcomed in the relevant industries.
- An embodiment of a downhole tool including a body having a function relevant to a selected environment, an electroactive polymer (EAP) anchor disposed with the body and configured to expand, upon application of an electric signal to the EAP, into loaded contact with a tubular member in which the downhole tool is to be set during use.
- A method for managing a borehole including running a tool to a selected depth in the borehole, applying an electric signal to the EAP, and anchoring the tool with the EAP.
- An embodiment of a borehole system including a borehole in a subsurface formation, a string in the borehole, a tool disposed within or as a part of the string.
- The following descriptions should not be considered limiting in any way. With reference to the accompanying drawings, like elements are numbered alike:
-
FIG. 1 is a schematic representation of a tool in a borehole environment with an Electroactive Polymer based anchor as disclosed herein; and -
FIG. 2 is a view of a borehole system including the tool as disclosed herein. - A detailed description of one or more embodiments of the disclosed apparatus and method are presented herein by way of exemplification and not limitation with reference to the Figures.
- Referring to
FIG. 1 , atool 10 is illustrated.Tool 10 comprises abody 12 and ananchor 14. The anchor comprises an electroactive polymer (EAP) configured in a toroidal shape that is disposed about thebody 12. Upon application of an electrical signal to theanchor 14, the EAP expands to come into contact with astructure 16 radially outwardly disposed of thetool 10. In embodiments, thestructure 16 is a tubular member or may be the borehole itself. In either case, the EAP expands into contact with thestructure 16 and creates a radially load thereon, which anchors thetool 10 in the selected location. In some embodiments, the EAP is provided at a radially outer surface thereof asurface texture 18 such as teeth, wickers, roughness, etc. to enhance gripping properties. Also, in some embodiments, the EAP creates a pressure seal as well as an anchor. EAP is commercially available and hence does not require specific disclosure of its makeup in this disclosure. - Also in embodiments, a
controller 20 may be placed in operable connection with the EAP. The controller may have its own electrical signal source, such as a battery or may include asensor 22 connected thereto. Such asensor 22 may be a temperature, pressure or depth sensor, for example. With thecontroller 20, the setting and unsetting of theanchor 14 may be autonomous in response to sensing a threshold parameter. The anchor may also be employed with out a controller but rather through the application of electrical signal through atether 24 by a surface operator at a selected time. - Referring
