Abstract: Methods and systems for operating a valve control system to control a valve in a wellbore include identifying a differential pressure arrangement of a plurality of differential pressure arrangements for actuating the valve to a desired state based on a differential pressure of at least two pressure sources of the wellbore and a present state of the valve. Once identified, the differential pressure arrangement of the at least two pressure sources are utilized to initiate actuation of the valve from the present state to the desired state.

Abstract: A system includes a tubular member (60) including a radially outer surface (60c) and a sensor assembly (128). The sensor assembly includes a strain sensor coupled to the radially outer surface. In addition, the sensor assembly includes a first coating having (134) a first hardness and a first tensile strength. The first coating encases the strain sensor (131,130) and at least part (64) of the outer surface. Further, the sensor assembly includes a second coating (136) having a second hardness that is greater than the first hardness and a second tensile strength that is greater than the first tensile strength. The second coating encases the first coating and at least another part (68) of the radially outer surface.

Abstract: A method includes releasing a flow device into a wellbore to travel towards a target device that is positioned in the wellbore and that is actuated by the flow device, monitoring for communications transmitted by the flow device. The method further includes identifying a condition of the wellbore from the communications.
