Abstract
An anchor system including a housing having a radial opening therein. A piston disposed within the housing and translatable therein. A slip in operable communication with the piston such that translation of the piston axially of the housing causes movement of the slip radially of the housing. The slip having a contact face that is nonparallel to an axis of the housing and nonparallel to a surface against which the slip is configured to be set. A method for anchoring a tool is included.
Claims16
An anchor system comprising:
- a housing having a radial opening therein;
- a piston disposed within the housing and translatable therein;
- and
- a slip initially affixed to the piston by a release member, the slip in operable communication with the piston such that translation of the piston axially of the housing causes movement of the slip radially of the housing, the slip while in a non-set position having a contact face that is nonparallel to an axis of the housing and nonparallel to a surface against which the contact face is configured to be set when in a set position, the contact face configured to bias a tool attached to the system to one surface of a casing or open hole in which the system is set during use.
An anchor system comprising:
- a housing having a radial opening therein, the radial opening including a chamfered downhole edge;
- a piston disposed within the housing and translatable therein;
- and
- a slip in operable communication with the piston such that translation of the piston axially of the housing causes movement of the slip radially of the housing, the slip while in a non-set position having a contact face that is nonparallel to an axis of the housing and nonparallel to a surface against which the contact face is configured to be set when in a set position, the contact face configured to bias a tool attached to the system to one surface of a casing or open hole in which the system is set during use.
A method for anchoring a tool with a positional bias comprising:
- attaching a tool to an anchoring system having a housing having a radial opening therein, a piston disposed within the housing and translatable therein, and a slip initially affixed to the piston by a release member and disposed within the housing in a run-in condition, the slip having a contact face that is nonparallel to a surface against which the contact face is to be set;
- deploying the slip at a target location in a borehole;
- and
- causing an uphole end of the tool to be biased against a selected portion of the borehole, the portion being related to the orientation of the slip and the contact face of the slip.
