ABSTRACT:
A sand control completion (100) for installation in a wellbore (102) includes first and second packers (114, 116) that define a first zone (110) in the wellbore (102). A production tubing (120) extends substantially through the first zone (110). Positioned between the first and second packers (114, 116) are a sand control screen (130), an inflow control valve (122) and a crossover valve (126). The sand control screen forms a first annulus (152) with the production tubing (120) and a second annulus with the wellbore (102). The inflow control valve (122) is operable to selectively allow and prevent fluid communication between the first annulus (152) and the interior of the production tubing (120). The crossover valve (126) is operable to selectively allow and prevent fluid communication between the production tubing (120) and the second annulus.
