Abstract: A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a fully closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular. Alternatively, the tubular can be in open hole and simply have openings for passage of fracture fluid and external isolators to allow fracturing in any desired order.

Abstract: One or more valves can be run into a string to land near associated ports in the string for injection or/and production service. When multiple valves are installed they can be initially configured to balance flow into or from a zone. The position of each valve can be altered without removal from the string preferably by a wireline shifting tool. One or more valves can also be removed and replaced when worn preferably using a wireline run tool. The valves can come with an integral sand control feature to facilitate production. Sensors to monitor well conditions and to transmit data to the surface can also be incorporated into the valve module.

Abstract: An in-flow control device controls fluid flow into a wellbore tubular using a permeable medium positioned in a flow space. The permeable medium induces a predetermined pressure differential in the flow space. The permeable medium may include separate elements having interstitial spaces and/or solid porous members. In arrangements, a filtration element may be positioned upstream of the flow space. In arrangements, the flow space may be formed in a plug member associated with the housing. In certain embodiments, a flow restriction element, such as a check valve, in the housing may provide parallel fluid communication with the bore of the wellbore tubular. Additionally, an occlusion body may be positioned in the flow space and configured to disintegrate upon exposure to a preset condition. The occlusion body temporarily seals the flow space so that a bore of the tubular may be pressurized.

Abstract: A packer setting device provides a buffered setting mechanism as a substantially incompressible fluid is selectively flowed into a compressible fluid chamber to compress a compressible fluid. This fluid transfer causes movement of a setting sleeve so that an associated packer device is set within a wellbore.

Abstract: A downhole arrangement including an outer housing, an inner housing disposed within the outer housing and defining with the outer housing a chamber, a turbine disposed within the chamber, and one or more nozzles disposed at the chamber capable of exhausting steam into the chamber. A method for moving a target fluid within a wellbore.

Abstract: A dewatering device is provided that can be inserted concentrically within the production tubing string of a natural gas-producing wellbore. The dewatering device includes a pressure-isolating chamber that is provided with a fluid inlet valve and a fluid outlet valve and associated gas lift valves. Compressed gas and soap are used to form a foamy liquid mixture that is lifted out of the chamber.

Abstract: Water is removed from a natural gas well using a piston pump is driven by a power fluid that is pumped into the wellbore. The power fluid is intermixed within wellbore water and pumped out of the wellbore along with the removed water.

Abstract: A coupler for gravel packing completions comprising an annular member having an upper end, a lower end, at least one flange disposed along an inner wall surface of the annular member intermediate the upper and lower ends, and at least one deformable portion is disclosed. The coupler may be used to connect one or more screens to a base pipe in a gravel packing completion by deforming the deformable portion such as by passing a swage over the outer wall surface of the annular member. In a similar manner, the coupler may also be used to connect a gravel packing completion component, such as an inflow control device to the base pipe of the gravel packing completion, to contemporaneously connect a screen section and a gravel packing completion component to the base pipe.

Abstract: A flow control device may include a body having at least two flow paths configured to convey the fluid. The flow paths may be hydraulically isolated from one another in the body and at least one of the flow paths may be selectively occludable. In certain arrangements, a filtration element may be positioned upstream of one or more of the plurality of in-flow control devices. The flow paths may utilize features such as chamber and openings in order to impose a specified pressure drop on the fluid flowing thereacross.

Abstract: A downhole abrading tool having a body with a first end for connection to a drill string, a cutting end, a drilling fluid passageway, a restrictor disposed within drilling fluid passageway, and an indicator chamber is disclosed. Upon exposure of the indicator chamber to a well environment due to excessive wear on the cutting end, the restrictor is actuated. Actuation of the restrictor restricts the flow of drilling fluid from the drilling fluid passageway into the well environment. The restriction of flow of drilling fluid from the drilling fluid passageway causes a pressure increase in the drilling fluid flowing through the well that can detected by an operator of the downhole abrading tool. The pressure increase provides an indication to the operator of excessive wear on the cutting end of the downhole abrading tool so that the downhole abrading tool can be removed from the well and replaced.
