An apparatus includes a base pipe and a fluid control material. The base pipe includes openings, and the fluid control material is mounted to the pipe to control fluid communication through the openings of the pipe. The fluid control material has a permeability that may be changed to selectively control the communication of well fluid through the openings.

Downhole flow control with selective permeability

Well servicing methods and systems are described, in one embodiment comprising installing a tool in a wellbore, the tool comprising a base tubular having a plurality of openings and a longitudinal bore adapted to fluidly connect to a tubular; a jacket tubular having a second plurality of openings; and an open, lofty, three-dimensional, non-fines stopping fibrous filter medium between the base tubular and the jacket tubular; and installing a first packer upstream of the tool and a second packer downstream of the tool. In some embodiments a sealant precursor composition may be fixed to the fibers. The sealant precursor composition may be activated to form a seal by a triggering chemical composition. This abstract allows a searcher or other reader to quickly ascertain the subject matter of the disclosure. It may not be used to interpret or limit the scope or meaning of the claims. 37 CFR 1.72(b).
