Well bladder system

Abstract

A well bladder is used to seal wellbores from intrusion. The well bladder is inserted, threaded, or otherwise arranged into the wellbore or an opening into the wellbore, and then expanded against the wellbore to seal against intrusion. The well bladder includes one or more layers, one or more axial sections, and one or more azimuthal sections. For example, the well bladder may be constructed from polyurethane, reinforcement, fabric, rubber, plastic, a composite material, or other flexible material. In a further example, the well bladder may include layers, mesh, fibers, stitching, or other suitable construction. In some embodiments, the well bladder may include a port configured to allow pressurization of the inner volume, a sensor configured to sense one or more properties of the well bladder, or both. A system may be configured to monitor the well bladder over time to ensure that the well bladder maintains the seal.
