Abstract: An apparatus for controlling a flow of fluid in a well includes a flow control device and a generator that generates electrical energy in response to a flow of an electrically conductive fluid. The flow control device may include an actuator receiving electrical energy from the generator, and a valve operably coupled to the actuator. The actuator may be configured to operate after a preset value for induced voltage is generated by the generator. The generator may use a pair of electrodes positioned along a flow path of the electrically conductive fluid to generate electrical energy. In one arrangement, one or more elements positioned proximate to the electrodes generate a magnetic field along the flow path of the electrically conductive fluid that causes the electrodes to generate a voltage. In another arrangement, the electrodes create an electrochemical potential in response to contact with the electrically conductive fluid.

Abstract: An apparatus and method for filling a defined space, such as an annulus around a production tubular within a wellbore, includes a compliant porous material. The compliant porous material can be compressed and maintained in a compressed state by incorporation of a deployment modifier which may be a water-soluble or oil-soluble adhesive or biopolymer, used as an impregnant, a coating, or a casing. The production tubular can be positioned at a desired location and the compliant porous material exposed to a deployment modifier neutralizing agent, which then dissolves or otherwise prevents the deployment modifier from continuing to inhibit the deployment. Thus, deployment can be delayed to an optimum time by controlling exposure of the deployment modifier to the deployment modifier neutralizing agent.
