Downhole high expansion anchor system

A method of operating an anchoring mechanism within a wellbore, comprising:

• conveying the anchoring mechanism into the wellbore on a workstring, wherein the anchoring mechanism comprises a first hub, an anchor pad, a wedge hub, and an extension mechanism comprising a deactivated mode and an activated mode, and wherein the extension mechanism is rotationally coupled to a pivot axle of the wedge hub and a pivot point of the anchor pad;
• radially moving the anchor pad towards an inner surface of a tubular in the wellbore by urging the wedge hub towards the first hub;
• anchoring the anchoring mechanism at a first target location by an outer surface of the anchor pad gripping the inner surface of the tubular;
• anchoring a service tool via the anchoring mechanism at the first target location;
• and
• operating the service tool to perform a wellbore service.

A system for performing a wellbore service, comprising:

• a surface logging facility;
• an anchoring mechanism comprising a first hub, an anchor pad, a wedge hub, and an extension mechanism comprising a deactivated mode and an activated mode, wherein the extension mechanism is rotationally coupled to a pivot axle of the wedge hub and a pivot point of the anchor pad, and wherein the anchoring mechanism is coupled to the surface logging facility by a workstring;
• a service tool coupled to the anchoring mechanism;
• an electric motor coupled to the anchoring mechanism;
• and
• a controller configured to control the electric motor to drive the wedge hub towards the first hub to cause an inner surface of the anchor pad to slide against a tapered outer surface of the wedge hub to move the anchor pad radially outward towards an inner surface of a wellbore tubular when the extension mechanism is in the deactivated mode,
• wherein the anchoring mechanism is configured to be anchored at a first target location by an outer surface of the anchor pad gripping the inner surface of the wellbore tubular, and
• wherein the service tool is configured to operate at the first target location to perform a wellbore service.
