Abstract: A sensor system for a sub-surface system is disclosed, comprising a pressure sensor positioned in a first orientation; a gravity sensor arranged proximate to the pressure sensor, the gravity sensor detecting gravitational force on the pressure sensor relative to the first orientation; and a data acquisition system operatively connected to each of the pressure sensor and the gravity sensor, the data acquisition system determining a gravity compensated pressure value detected by the pressure sensor corrected for gravitational force on the pressure sensor relative to the first orientation.

Abstract: The present disclosure relates to apparatuses and methods for terminating communication on a communication line between a carrier and at least one node located at a subsurface location. The apparatus may include a control member configured to initiate termination of communication in response to a controlled signal. The apparatus may also include a communication linkage configured to terminate the communication in a manner that cannot be remotely restored in response to the control member. The apparatus may also include a power source to maintain power to the communication linkage termination operation. The apparatus may be configured to use energy from the communication line to cause the communication linkage to terminate communication. The apparatus may be configured to use a communication linkage that is at least partially consumable. The method includes the use of the apparatus.

Abstract: A method of determining the position of a valve includes, measuring pressure at a first location within a bore and measuring pressure at a second location within the bore wherein the first location and the second location are positioned on opposing longitudinal sides of the valve. The method further includes analyzing values from the measuring and attributing characteristics of the analyzing to specific valve positions.
