    摘要： Systems and methods for characterizing a spatial frequency of interface regions within a subterranean formation. A first method may include drilling a wellbore with a drilling assembly and measuring a downhole parameter during the drilling. The downhole parameter may be indicative of a lithology of a portion of the subterranean formation that is proximal to the drilling assembly. The first method also may include calculating an information entropy of the downhole parameter and characterizing the spatial frequency of the interface regions based upon the information entropy. A second method may include calculating the information entropy as a function of distance within a first wellbore and characterizing the spatial frequency of the interface regions. The second method also may include drilling a second wellbore within the subterranean formation and regulating the drilling based upon the spatial frequency of the interface regions. The systems include systems that perform the methods.

    摘要： Provided are methodologies and systems employing an array of independently operated flow control valves at an uphole location in each of a plurality of legs of a multilateral well to facilitate resolution and effective execution of efficient production plan and to improve performance. Along each leg of the multilateral well, a flow-control valve may be located downhole of a confluence between the respective leg and another leg and uphole of the well completion portion (production and/or injection component) of the respective leg. Each valve is operable independently of each other and of any valving in the completion component. Data regarding the nature and rate of production from each leg may be acquired from downhole sensors located at or about each flow control valve. The acquired data may be processed through a reservoir-well computerized model to resolve optimal valve settings across the valve array.

    摘要： In a well related to the production of hydrocarbons, an injection apparatus including: a base pipe including a radial port; an in-flow control device including a flow restriction device and a housing, with the housing being external and concentric of the base pipe. The housing includes a closed end portion and an open, opposite end portion and a housing channel communicating the opposite end portion. The flow restriction device is disposed at an intermediate location along the housing channel and adapted to control a rate of flow along the housing channel. A fluid transmissive screen is concentric of the base pipe and extends from the open, opposite end portion of the housing. A check valve assembly is interposed between the opposite end portion of the housing and a screened space.
