The objective of water-shutoff treatments in gas wells is to reduce water production and at the same time increase gas-production rates and producible gas reserves. Several field treatments, focused on water abatement in gas wells, have demonstrated that a sequential gel-/gas-injection technique in fractured gas reservoirs was successful in reducing water production and increasing gas production. Additional efforts focused on improving gel placement in fractured and matrix reservoirs to improve treatment efficiency. Field-scale simulations demonstrated the merits of proper gel-placement technique by use of a foam to displace the gelant away from the wellbore in matrix and fractured reservoirs.
