Abstract
A completion assembly includes a completion string and a valve assembly. The completion string is disposed within a wellbore. The valve assembly is coupled to a downhole end of the completion string and includes a housing, a sleeve, a compression spring, and a rotatable indexing assembly. The housing includes a first fluid port and a first shoulder. The housing defines, with a wall of the wellbore, an annulus. The sleeve is disposed within the housing and includes a second fluid port, an indexing slot, and a second shoulder. The valve assembly receives fluid from the completion string to increase a pressure of an inner volume of the valve assembly with respect to the annulus, generating a pressure differential causing the sleeve to axially move, moving the sleeve between an open position with the second fluid port open, and a closed position with the second fluid port closed.
