Abstract
An anchor, including a housing, a slip in contact with the housing, and a power drive gear mounted in the housing and disposed to drive the slip. A method for operating an anchor, including supplying an input to the anchor, driving a slip of the anchor to a position other than a position occupied by the slip immediately prior to the input, wherein the driving comprises rotating a power drive gear. A wellbore system, including a borehole in a subsurface formation, a string in the borehole, and an anchor disposed within or as a part of the string.
Claims20
An anchor, comprising:
- a housing;
- a slip in contact with the housing;
- and
- a power drive gear mounted in the housing and disposed to drive the slip;
- and
- a biaser in direct contact with the power drive gear.
An anchor, comprising,
- a housing;
- a slip in contact with the housing;
- and
- a power drive gear mounted in the housing and disposed to drive the slip, wherein the slip includes teeth that are complementary for the power drive gear and engaged therewith.
A method for operating an anchor, comprising:
- supplying an input to the anchor;
- driving a slip of the anchor to a position other than a position occupied by the slip immediately prior to the input, wherein the driving comprises rotating a power drive gear, with or against a bias provided by a biaser in direct contact with the power drive gear.
A method for operating an anchor, comprising:
- supplying an input to the anchor;
- driving a slip of the anchor to a position other than a position occupied by the slip immediately prior to the input, wherein the driving comprises rotating a power drive gear wherein the charging is by driving the power drive gear with the slip during manufacture of the anchor to a higher potential energy condition.
