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. Well log 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: 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.

Abstract: A technique facilitates collecting data, related to a fracturing, run-in-hole, or pull-out-of hole operation. A frac plug is provided with electronics for obtaining the desired information related to the operation. For example, the frac plug may be constructed with electronic sensors, a digital storage device, and a power supply or other power related equipment. Depending on the application, the frac plug may be a composite frac plug, degradable frac plug, dummy frac plug, or other suitable frac plug. Retrieval of the information obtained may be done via coupling with an associated device, e.g. inductive or physical coupling, by utilizing a broadcast transmitter/receiver, by physical retrieval of the storage device, or by physical retrieval of the dummy frac plug.

Abstract: A technique facilitates improved setting of downhole devices, e.g. frac plugs. The technique utilizes a setting tool, e.g. a disposable setting tool, which integrates the functionality of a wireline adapter kit to provide a compact disposable solution for setting downhole devices. The setting tool comprises a self metering system which slows an otherwise violent setting action to a controlled setting sequence. The self metering system enables avoidance of the use of slow burn charges sometimes used in conventional setting tools.

Abstract: An apparatus that is usable with a well includes a tubular assembly and an expansion tool. The tubular assembly has a radially contracted state and includes a restriction. The restriction is adapted to catch an object that is deployed into the well to form a fluid barrier when caught by the restriction. The expansion tool is deployed downhole with the tubular assembly inside a tubing string. The expansion tool is adapted to deform the tubular assembly to anchor the tubular assembly to the tubing string.

Abstract: An embodiment may take the form of a method usable with a well including communicating an untethered object downhole in the well to land the object in a restriction to form a fluid barrier, and using an agent carried by the untethered object to seal at least one gap in the fluid barrier. Another embodiment may take the form of an apparatus usable with a well having a solid component to be deployed and be communicated downhole as an untethered object to land in a restriction in the well to form a fluid barrier and an agent attached to the solid component to seal at least one gap in the fluid barrier.

Abstract: A system includes a casing string and a buoyancy assist tool that is disposed in the casing string. The buoyancy assist tool includes a tubular body, a wiper plug assembly, and a degradable member. The wiper plug assembly is disposed inside the central passageway of the tubular body, and the degradable member retains the wiper plug assembly to the tubular body.

Abstract: A storable composition for oilfield application including a slurry of a carrier fluid and a particulate blend made of proppant; the particulate blend comprising at least a first amount of particulates having a first average particle size between about 100 and 5000 ?m and at least a second amount of particulates having a second average particle size between about three and twenty times smaller than the first average particle size; such that a packed volume fraction of the particulate blend exceeds 0.74 and the particulate blend volume is sufficient to substantially avoid settling of the particulate in the carrier fluid.

Abstract: A technique includes installing a tubing string having a toe initiator valve in a wellbore; and opening the toe initiator valve to establish fluid communication between an interior of the string and a region outside of the string. The technique includes using the fluid communication established by the open toe initiator valve to communicate a degradable object downhole to land in a seat of the string; and performing a downhole operation using a fluid barrier resulting from the landed object.
