    摘要： Oil recovery can include providing a tubing string and isolation devices to define isolated intervals for an existing well previously operated using plug-and-perf and primary production. Valve assemblies are installed in respective isolated intervals, each valve assembly including at least two valves. The valve can be operated in open and closed configurations, and at least one open configuration provides choked flow via an elongated passage. The valves can have a housing and a shiftable sleeve. The valve assemblies can be operated to provide a desired openness based on the injectivity or other properties by shifting the sleeves of the valves. Different flow resistance levels can be provided to facilitate enhanced operations for water flooding and other oil recovery processes.

    摘要： A flow control apparatus comprising: a housing, a housing passage disposed within the housing, a subterranean formation flow communicator for effecting flow communication between the subterranean formation and the housing passage, a flow control member, displaceable, relative to the subterranean formation flow communicator, for effecting at least opening of the subterranean formation flow communicator There is further provided a first actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. There is also provided a second actuation system for actuating displacement of the flow control member relative to the subterranean flow communicator. Relative to the central longitudinal axis of the housing passage, the first actuation system is angularly spaced from the second actuation system.

    摘要： Apparatuses, systems and methods for producing hydrocarbon material from a subterranean formation using a displacement process are disclosed. In one aspect, there is provided a method of controlling hydrocarbon production of hydrocarbon material disposed within a subterranean formation by a displacement process via a plurality of flow communication stations of an injection well. Characteristics of a supplied production-initiating fluid are determined uphole of the flow communication stations for a plurality of states of the injection well, wherein in each of the states of the injection well a different subset of the flow communication stations are disposed in an opened condition and a different subset of the flow communication stations are disposed in a closed condition. Characteristics may be determined at the surface, for example, at the wellhead. A state of the injection well that optimizes one or more operating parameters is determined. A condition of the flow communication stations is in accordance with the determined state of the injection well.
