Abstract: A method of managing pressure in a wellbore having an annulus defined between a wall of the wellbore and a work string that includes drill pipe, a service tool, and a lower completion, the method comprising: performing the following operations, running the work string in hole down the wellbore while maintaining an annulus pressure while maintaining a hydrostatic pressure within the work string above a valve of the service tool, wherein the valve is configured to pressurize the annulus without pressurizing the work string.

Abstract: An array of sensors provided on the outside of a tubular string for measuring a property within the tubular string. The array of sensors may include a plurality of connected sensors, wherein at least one of the plurality of connected sensors is at least partially encompassed in a shroud. A snorkel line may extend from the shroud, the snorkel line capable of coupling with a sensor port in a tubular of the tubular string. The snorkel line may establish fluid communication between one of the sensors at least partially encompassed in the shroud and a corresponding sensor port of a tubular in the tubular string.

Abstract: Provided are systems and methods for controlling the fluid flow to and from the flow ports of an autonomous inflow control device (AICD). Features may include the addition of a ball check valve to the AICD. A well system may comprise: a production tubing; a flow control device, wherein the flow control device is disposed onto the production tubing; and a ball check valve disposed between the flow control device and the production tubing to restrict flow into the production tubing through a port in the flow control device, wherein the ball check valve comprises a housing and a ball.
