    摘要： Systems and methods for stimulating a plurality of zones of a subterranean formation to increase production of reservoir fluids therefrom. The subterranean formation contains a well that includes a liner that defines a liner conduit, and the systems and methods include stimulating the plurality of zones with a stimulation assembly that is present within the liner conduit without requiring removal of the stimulation assembly from the liner conduit. The stimulation assembly includes a perforation device, which is configured to selectively form one or more perforations in a plurality of portions of the liner, and a resettable sealing device, which is configured to fluidly isolate the plurality of portions of the liner from a plurality of respective downhole portions of the liner. The fluid isolation provides for selective introduction of a stimulant fluid to a selected zone of the subterranean formation that is associated with a corresponding portion of the liner.

    摘要： Wellbore flow-control assemblies define a flow-controlled fluid conduit that selectively conveys a fluid flow, including fluid outflow and fluid inflow, between a subterranean formation and a casing conduit. The wellbore flow-control assemblies include a sacrificial flow-control device that defines a first portion of the flow-controlled fluid conduit and a directional flow-control device that defines a second portion of the flow-controlled fluid conduit. The sacrificial flow-control device resists the fluid flow prior to a flow-initiation event and permits the fluid flow subsequent to the flow-initiation event. The directional flow-control device permits one of fluid outflow and fluid inflow and resists the other.

    摘要： A method of forming an elevated pressure proppant-containing fracturing fluid for direct injection into a wellbore that reduces exposure of a substantial amount of the pumping equipment to the abrasive effects of proppant, as compared to conventional pumping equipment. The method includes providing a high pressure fluid stream to a nozzle having an inlet and an exit; accelerating the high pressure fluid stream through the nozzle from the inlet to the exit to increase the velocity thereof; providing a low pressure stream comprising a proppant to a suction chamber, the suction chamber positioned adjacent the nozzle exit; and mixing the low pressure fluid stream comprising a proppant with the high pressure fluid stream to form an elevated pressure proppant-containing fracturing fluid. A method for fracturing and a system for forming an elevated pressure proppant-containing fracturing fluid for injection into a wellbore are also provided.

    摘要： Systems and methods for supplying a stimulant fluid to a subterranean formation, including apportioning a production liner assembly into a plurality of treatment zones and providing the stimulant fluid to at least an initial treatment zone of the plurality of treatment zones. Apportioning the production liner assembly into the plurality of treatment zones may include utilizing a longitudinal flow control device to fluidly isolate at least a first portion of the plurality of treatment zones from at least a second portion of the plurality of treatment zones and/or placing an outlet of a stimulant fluid supply device proximal a selected treatment zone. May include providing the stimulant fluid through one or more outflow control devices. The systems and methods also may include receiving a reservoir fluid through one or more inflow control devices.

    摘要： An improvement to a centralizer that may reduce the torque required to rotate a casing in a borehole during primary cementing is disclosed. In a first embodiment, the improvement is adapted to a bow spring type centralizer having intermediate fixed and slidable sleeves with each sleeve circumscribed by an end band. The end bands are connected to each other by a plurality of bow springs. The improvement includes interposing a sleeve bearing between each end band and its respective intermediate sleeve. The sleeve bearings may be attached to the intermediate sleeves to permit their rotation with the casing relative to the stationary end bands and bow springs. Alternatively, the intermediate sleeves may be eliminated and the sleeve bearings interposed directly between the outer surface of the casing and inner surfaces of their respective end bands.
