Abstract: A wireless communications system includes a network of acoustic modems for communicating messages between downhole equipment and a surface control and telemetry system. The acoustic modems include multi-channel acoustic receivers that are uniquely deployed along an acoustic transmission medium to provide spatial diversity. Acoustic signals received on the multiple receiver channels are combined and filtered using a Bayesian-type filter to reduce noise.

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. Subsurface data can be analyzed to determine position of the at least one feature in 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: Systems and methods facilitate pumping of various fluids such as well fluids. An electric submersible pumping system is constructed with an outer housing that contains an integrated pump and motor. The pump may include an impeller disposed within a stator of the motor. The integration of the pump and the motor enables elimination of various components of traditional electric submersible pumping systems to thus provide a simpler and more compact system for pumping fluids.
