Abstract: A technique facilitates regulation of pressure in a well to avoid deleterious effects. The technique involves use of a completion deployed downhole in a borehole. The completion may comprise a variety of equipment assembled to facilitate a desired injection operation. A choke is positioned below, i.e. downhole, of the equipment. When an injection fluid is delivered down through the completion, the choke is able to provide a desired pressure regulation. For example, the choke may be controlled or otherwise utilized so as to control pressure of the injection fluid such that the injection fluid above the choke is maintained at a pressure higher than the liquid to gas transition level of the injection fluid.

Abstract: Methods are provided for extracting thermal energy from a geothermal reservoir having at least one feature extending therethrough, which involve drilling or accessing a production well that intersects the at least one feature, wherein the at least one feature provides a flow path of pressurized geothermal fluid into the production well.

One or more interventions, or combinations of interventions, can be performed to open the feature or otherwise enhance the flow rate of pressurized geothermal fluid carried by the feature into the production well. The intervention(s) can be performed on multiple features that connect to the production well. The method can also be applied to multiple production wells.

Abstract: A technique facilitates use of an inductive coupler assembly with casing, e.g. well casing. An inductive coupler is formed as a female inductive coupler with an inductive coil. The inductive coupler is constructed for sliding movement along an exterior of the casing so that it may ultimately be positioned and secured at a suitable location along the casing. The inductive coupler is designed for connection with an electrical device, e.g. a sensor. The inductive coupler facilitates the transfer of sensor data and/or power signals across the casing. Signal transfer across the casing is further enabled by a male inductive coupler positioned within the casing at a location which allows it to cooperate with the exterior, female inductive coupler.
