摘要： A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves one series of which can be put in the wide open position after run in for gravel packing and fracturing zones one at a time or in any desired order. These valves are then closed and another series of valves can be opened wide but with a screen material juxtaposed in the flow passage to selectively produce from one or more fractured zones. An annular path behind the gravel is provided by an offset screen to promote flow to the screened production port. The path can be a closed annulus that comes short of the production port or goes over it. For short runs an exterior screen or shroud is eliminated for a sliding sleeve with multiple screened ports that can be opened in tandem.

摘要： A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by extendable members that are located behind isolation valves. The extendable members can comprise a biodegradable plug that allows extension of the extendable members by application of pressure. With the plug remained in place, additional pressure can be delivered until at least a portion of the degradable material is pushed onto the surface of the formation. At least a portion of the pushed degradable material provides a seal between the end of the extendable members and the surface of the formation to allow pressure to build until the formation frac gradient is exceeded and the formation is fraced.

摘要： Systems and methods for increasing fluid flow characteristics within a hydrocarbon production tubing string within a wellbore. An expansion member is passed through the interior flowbore of one or more production tubing string members. The expansion member smoothes the interior surface of the flowbore and may radially expand the interior surface of the flowbore.

摘要： An apparatus and method for perforating a liner, fracturing a formation, and injection or producing fluid, all in one trip with a single tool. The tool has a plurality of outwardly telescoping elements (12, 14) for perforation and fracturing. The tool also has a mechanical control device for selectively controlling the fracturing of the formation and the injection or production of fluids through the telescoping elements.

摘要： 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.

摘要： A flow conduit may have at least one orifice is in the vicinity of a flow source. The source is at least partially covered (and flow blocked by) an optional temporary coating or barrier. The flow pathway between the orifice and the source is temporarily blocked with a degradable material or barrier. The material disintegrates (e.g. under the influence of time or temperature) to optionally produce a product that removes the temporary coating in the area adjacent the barrier. The method is useful in one non-limiting context of recovering hydrocarbons where the flow conduit is the casing or liner of the well and the flow source is a subterranean reservoir where the temporary coating is a filter cake.

摘要： An assembly method for a downhole screen is disclosed. In the preferred embodiment, the filtration layer is slipped over a perforated base pipe and an expansion technique is used to increase the base pipe diameter to the point where, preferably, an interference fit exists. The expansion can be fully underneath the filtration layer or can be done in discrete zones. The finished assembly can still be expanded further downhole, such as, for example, in open hole completions. An outer protective shroud can be employed over the filtration layer when the expansion of the base pipe occurs.

摘要： A packer or bridge plug uses a sealing element made from a shape memory polymer (SMP). The packer element receives heat to soften the SMP while the element is compressed and retained. While so retained, the heat is removed to allow the SMP to get stiff so that it effectively seals a surrounding tubular. High expansion rates are possible as the softness of the material under thermal input allows it to be reshaped to the surrounding tubular from a smaller size during run in and to effectively retain a sealed configuration after getting stiff on reduction in its core temperature while longitudinally compressed.
