Mill, whipstock, and anchor assembly, method and system

Abstract

A mill, whipstock, and anchor assembly, including a mill, a whipstock attached to the mill, an anchor attached to the whipstock, the anchor having a kinetic energy releaser, the releaser including an energetic material, and a sensor in the assembly, the sensor configured to respond to a selected parameter by sending a first signal. A method for setting an anchor of the assembly, the method including causing a condition to exist at the sensor that at least reaches a threshold for the sensor to generate the first signal, igniting the energetic material, disappearing the releaser, and applying kinetic energy to a slip to set the anchor. A borehole system, including a borehole in a subsurface formation, a string disposed in the borehole, and the mill, whipstock, and anchor assembly disposed within or as a part of the string.
