摘要： Gravel packing compositions or fluids and/or methods pack a wellbore in a subterranean formation, wherein the wellbore comprising a cased section and an uncased section. The gravel packing compositions or fluids include gravel and a carrier fluid including an invert emulsion fluid are pumped into the wellbore, wherein the invert emulsion fluid including an oleaginous external phase having a synthetic polymer viscosifier and/or an organophilic clay viscosifier therein, a non-oleaginous internal phase, and an emulsifier stabilizing the oleaginous external phase and the non-oleaginous internal phase. When the organophilic clay viscosifier is present in the oleaginous external phase, the organophilic clay is swelled with a polar solvent that is added to the oleaginous phase prior to the addition of the organophilic clay.

摘要： A technique to facilitate removal of various types of particulates from fluids during well operations. The technique may employ a skid positioned at a surface location. A filtration system is mounted on the skid to enable filtration of particulates as the subject fluid flows from a system inlet to a system outlet. The filtration system comprises a bank of filtering stages arranged generally horizontally on the skid. For example, a first stage may be constructed with a generally horizontal vessel containing a first filter arranged to filter particulates from the fluid. The first stage also may comprise a magnet positioned to retain ferrous debris. Additionally, a second stage receives fluid exiting from the first stage and contains a second filter for further filtering of particulates from the fluid.

摘要： Systems and methods for directing a pressure differential below a screen in a shale shaker to urge fluid to pass through the shaker. A support unit including a tray and a movable arm supports a pressure differential generating device. The support unit can be positioned relative to the shale shaker with the tray in position to collect fluid passing through a screen of the shale shaker. The pressure differential generating device generates a pressure differential that pulls fluid through the screen. One or more slot trays are positioned between the pressure differential generating device, the screen, and some supporting structure of the frame of the shaker. The slot trays distribute the pressure differential around the screen.

摘要： An apparatus, a system and a method for reinforcing a screen has a screen rod assembly extending from a first end to a second end. The screen rod assembly encloses an interior. A spring-loaded plunger is located in the interior and adjusts the length of the screen rod assembly. A ball joint is on the screen rod and defines sections of the screen rod assembly that bend around the ball joint to reduce the length of the screen rod. A sleeve extends from a screen with segments separated by a fold line extending along a width of the screen. The sleeve receives the screen rod assembly to reinforce the screen. In an embodiment, a screen pinch assembly is defined where the sleeve engages a retention clasp of a screen tensioning system that receives the screen. The screen pinch assembly holds the screen in place.
