Abstract

A chemically-activated inflow control device. The inflow control device comprises a tubular body configured to be connected in series to joints of sand screen in a wellbore. The tubular body forms a bore that receives a slotted base pipe. At the same time, the tubular body is fluidly connected with the sand screen joints, forming an annular flow path between the slotted base pipe and surrounding sand screen. Production fluids moving into the sand screen pass across a component that degrades in the presence of water. If the well begins producing water, the degradable component will dissolve, activating a sealing mechanism within the inflow control device and closing a restricted flow path. In this way, production fluids are not able to travel from the annular flow path into the bore of the slotted base pipe. A method for completing a wellbore having a chemically-activated inflow control device is also provided.
