Abstract: A system for installation in a well bore includes a flow control device and a control unit coupled to the flow control device. The flow control device is changeable from a first state to a second state. The first state corresponds to a first mode of fluid communication between an interior of a tubular conduit of a completion string and an annulus between the tubular conduit and a wall of the well bore. The second state corresponds to a second, different mode of fluid communication between the interior of the tubular conduit and the annulus. The control unit is coupled to the flow control device to change the flow control device between the first and second states. The control unit is actuated to change the flow control device in response to pressure in the well bore.

At least a first and a second interchangeable adapter components are operable to couple to the adapter component engaging portion. The first adapter component is adapted to perform a first function and the second adapter component is adapted to perform a second function.

Abstract: A system for oscillating compressible working fluid in a wellbore defined in a subterranean formation includes a fluid supply and a fluid oscillator device. The fluid supply communicates compressible working fluid into a conduit disposed within the wellbore. The fluid oscillator device is configured to reside in the wellbore. The fluid oscillator device includes an interior surface that defines an interior volume of the fluid oscillator device, an inlet into the interior volume, and an outlet from the interior volume. The interior surface is static during operation to receive the compressible working fluid into the interior volume through the inlet and to vary over time a flow rate of the compressible working fluid from the interior volume through the outlet.

Abstract: A system for producing fluids from a subterranean zone comprises a tubing string disposed in a well bore, the tubing string adapted to communicate fluids from the subterranean zone to a ground surface. A downhole fluid lift system is operable to lift fluids towards the ground surface. A downhole fluid heater is disposed in the well bore and is operable to vaporize a liquid in the well bore. A seal between the downhole fluid lift system and the downhole fluid heater is operable to isolate a portion of the well bore containing the downhole fluid lift system from a portion of the well bore containing the downhole fluid heater. A method comprises: disposing a tubing string in a well bore; generating vapor in the well bore; and lifting fluids from the subterranean zone to a ground surface through the tubing string.

Abstract: A downhole oil and water separator for an oil well includes a water-selective membrane disposed in a production flowpath of the well. The water-selective membrane is operable to selectively pass water from the production flowpath to a disposal zone to increase the concentration of oil in the production flowpath at the surface.

Abstract: Systems and techniques, including computer programs, for monitoring and controlling thermal recovery involve generating input parameters for use in real time monitoring and controlling of a thermal recovery operation for a reservoir. The input parameters to a thermal generator are generated using a reservoir simulator and an economic model, and the input parameters have a corresponding predicted output of the thermal recovery operation. Data indicative of actual output from the reservoir is received, and the reservoir simulator is automatically updated based on a comparison of the data indicative of the actual output with the predicted output.

Abstract: An expandable liner hanger system includes an expandable liner hanger and an expansion cone having a first outer diameter when driven through the expandable liner hanger in a first direction to expand the expandable tubing. The expandable liner hanger system also includes a polished bore receptacle having a lower end coupled to an upper end of the expandable liner hanger by a coupling, the coupling having an inner diameter smaller than the first outer diameter. In the run in condition, the expansion cone is positioned below the coupling.

Abstract: The recovery of hydrocarbons from hydrocarbon bearing rock, sands or other geological materials (collectively “rock”) uses a recovery fluid. In certain embodiments, the recovery fluid includes miscible compounds or an azeotrope-forming mixture (including an azeotrope), used alone or with other compositions. Two or more compounds in the recovery fluid yield a mixture with different and/or improved characteristics over those of one or more of the component compounds in both liquid and vapor states.

Abstract: Methods, systems, and tools for provide for delivering a particulate-laden slurry to a subterranean portion of a well for operations including gravel packing and/or frac packing.

At least a first and a second interchangeable adapter components are operable to couple to the adapter component engaging portion. The first adapter component is adapted to perform a first function and the second adapter component is adapted to perform a second function.

Abstract: A system and method for fracturing an earth formation surrounding a borehole includes an elongate conduit positioned in the borehole. A packer assembly is provided about the conduit and is adapted to seal an annulus between the conduit and the borehole. A packing passage is provided and adapted to communicate a first side of the packer assembly to the annulus between the conduit and the borehole on a second side of the packer assembly. The conduit has at least one inlet into the conduit on the second side of the packer assembly adapted to allow flow from outside of the conduit to the interior of the conduit. The conduit has at least one ported sub having at least one lateral jet aperture therein adapted to direct fluids within the conduit into the earth formation to fracture the earth formation.

Abstract: A system and method for controllably separating a conduit into an upper portion and a lower portion. The system includes a first valve in the upper portion of the conduit above a point of separation, and a second valve in the lower portion of the conduit below the point of separation. When the conduit is separated, the valves are actuated to cease flow therethrough and prevent loss of fluids into the seawater. A hang-off tool in the lower portion of the conduit engages the well and supports the lower portion of the conduit.
