    摘要： Systems and methods for improving reservoir fluid recovery from fractured subterranean formations. The methods may include injecting a pressurizing fluid into an injection fracture that extends within a subterranean formation and producing a produced fluid from a production fracture that extends within the subterranean formation. The production fracture is spaced apart from the injection fracture and is in indirect fluid communication with the injection fracture via a portion of the subterranean formation that extends therebetween and the pressurizing fluid injection provides a motive force for the production of the produced fluid. The methods further include injecting a foaming agent into the production fracture to limit production of the pressurizing fluid from the production fracture. The systems may include hydrocarbon production systems that may be utilized to perform the methods and/or that may be created while performing the methods.

    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： 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： 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.

    摘要： A method for recovering oil from a subterranean, hydrocarbon-bearing formation includes at least one injection well and injecting a carrier fluid including a diverting agent into a high permeability pathway within the formation. An activating fluid is injected into the high permeability pathway within the formation, resulting in the precipitation or swelling of the diverting agent. The permeability of the high permeability pathway is decreased within the formation containing the diverting agent to a permeability less than the permeability of the adjacent areas of the formation. The carrier fluid may have a predetermined residence time within the formation prior to injecting an activating fluid; the step of injecting a carrier fluid comprising a diverting agent and injecting an activating fluid may be repeated. A mineralization fluid may be injected that is oversaturated or becomes oversaturated upon interacting with the acid gas that causes mineral precipitation to seal off high-permeability pathways.
