    Abstract: A sand control screen assembly having a protective shroud or jacket that provides a controlled offset between the shroud and a filter medium. The sand control screen assembly also includes a base pipe having a drainage layer positioned therearound for preventing the flow of particulate material of a predetermined size therethrough and allowing the flow of production fluids therethrough.

    Abstract: A sand control screen assembly includes a base pipe having openings having non-uniform cross-section. The sand control screen assembly can also include a drainage layer positioned about the base pipe, a filter medium, and a protective shroud. The sand control screen assembly prevents the flow of particulate material of a predetermined size therethrough and allows the flow of production fluids therethrough.

    IPC: G01N17/04

    CPC classification number: G01N17/046

    Abstract: Disclosed are systems and methods for detecting the erosion and corrosion effects of solids during oil and/or gas production. An erosion corrosion detector (BCD) is positioned in fluid communication with a pipe in a production facility such that a sensor element of the BCD contacts at least a partial stream of produced fluid in the pipe. Changes in one or more physical measurement of the BCD and/or changes in pressure drop across the sensor element are monitored over time. The changes are interpreted to identify whether there is loss of materials (e.g., metal) in the production facility, quantify of this loss, and determine the mechanisms through which this loss is occurring. A control system can receive the change in the physical measurement and/or the pressure drop over time as input into a control strategy for controlling a well control valve to control a rate of production of well fluids.

    Abstract: A sand control screen assembly having a drainage layer that provides a controlled offset between the drainage layer and a filter medium and/or a base pipe. The sand control screen assembly also includes a protective shroud or jacket positioned about the filter medium. The sand control screen assembly can be utilized for preventing the flow of particulate material of a predetermined size therethrough and allowing the flow of production fluids therethrough.

    IPC: E21B43/10 ,  E21B43/08

    Abstract: A sand control screen assembly includes a base pipe having multiple first openings through a thickness of the base pipe, where at least one of the first openings is characterized by a non-uniform cross-section, where each first opening has a first portion and a second portion adjacent to the first portion, where the first portion is disposed adjacent to an inner surface of the base pipe, where the second portion is disposed adjacent to an outer surface of the base pipe, where the second portion includes multiple channels, where each channel extends outward and upward relative to the first portion, where each channel includes a wall having a side wall edge and a base wall edge, where an interface surface between the side wall edge and the base wall edge is a planar surface.
