Abstract
A completion assembly defines a throughbore and comprises an isolation valve configurable between an open state (permitting fluid to flow through the throughbore) and a closed state (preventing fluid from flowing through the throughbore). A method for use in installing the assembly into a wellbore in a single trip comprises running the assembly into the wellbore with the valve in the open state until a downhole end of the assembly reaches a target position; injecting a fluid through the throughbore and the valve when the valve is in the open state; configuring the valve into the closed state; and performing a pressure integrity test of the throughbore above the valve. The valve is configurable between the open and closed states without any requirement for the valve to be mechanically engaged by an activation member or a tool whilst the valve receives power from a power source.
