Abstract: A method and apparatus for determining a pressure in an annulus between an inner casing and an outer casing. An acoustic transducer is disposed within the casing at a selected depth within the inner casing and is configured to generate an acoustic pulse and receive a reflection of the acoustic pulse from the inner casing. A time of flight is measured of the acoustic pulse to the inner surface of the inner casing. An inner diameter of the inner casing is determined from the time of flight. The pressure in the annulus is determined from the inner diameter. A processor can be used to measure time and determine inner diameter and annulus pressure.

Abstract: An axial-to-rotary movement configuration including a sleeve having a sleeve angulated castellation and a lug receptacle, a lug disposed in the lug receptacle, and a mandrel disposed in part within the sleeve, the mandrel having a mandrel angulated castellation nestable with the sleeve angulated castellation and further including an extension cam surface and a ramp, the ramp having a limit surface and configured to allow rotational motion of the sleeve relative to the mandrel in one direction only.
