    摘要： An adaptable anchor includes a frame; an arm articulated to the frame; a pad connected to the arm at a distance from the articulation with the frame; a wedge movably mounted to the frame and in wedging contact with the arm; a biasing member disposed to selectively apply a biasing energy between the frame and the wedge; and a degradable retainer preventing application of the biasing energy until degraded. An embodiment of a borehole system includes a borehole in a subsurface formation; a tubular member disposed in the borehole; and an adaptable anchor as in any prior embodiment in operable contact with the tubular member. An embodiment of a method for anchoring a tool in a borehole includes running the adaptable anchor into a borehole; degrading the degradable retainer; urging the wedge into contact with the arm with the biasing member; and displacing the pad.

    摘要： A pressure control valve for downhole treatment operations includes a valve body including an inlet, an outlet, and a valve seat. A valve assembly is arranged in the valve body. The valve assembly includes a valve member selectively positionable on the valve seat to control fluid flow through the valve body. A piston assembly including a piston and a control fluid inlet is arranged in the valve body. The piston is operatively connected to the valve assembly. The piston is operable to bias the valve member toward a closed configuration upon exposure to a control fluid.

    摘要： A fluid injection valve comprising: a valve body including a first end having a first opening, a second end having a second opening, an outer surface and an inner surface defining a fluid pathway extending between the first end and the second end; a seat arranged along the fluid pathway; a restriction device selectively abutting the seat; a biasing member arranged in the fluid pathway abutting the restriction device; urging the restriction device against the seat; a biasing element having a biasing force urging the biasing member against the restriction device; and a magnet functionally connected to the biasing element, the magnet selectively forcing the biasing member axially outwardly of the restriction device against the biasing force.
