Abstract: Apparatus having a drivebox including a motor, a drive connected to the motor, a suitable number of adjustment brackets, and a set of adjustment gussets. A basket is connected to the drivebox through the adjustment brackets and adjustment gussets, and drivebox imparts a sifting motion onto the basket. The basket has a housing, an infeed end, an discharge end, at least one screening deck contained therein, and positioned at a screening deck angle. The apparatus is of a modular design which enables changing the screening deck angle while installed in a facility and without substantial disassembly.

Abstract: A scalping insert includes a scalping surface having a plurality of scalping slots therethrough, and a vertical base portion. A shaker screen assembly includes a screen frame having at least one slot. A scalping insert is positioned in the at least one slot of the screen frame. Processing fluid using a shaker screen assembly includes providing a flow of fluid to the shaker screen assembly and flowing the fluid through both a scalping surface and a screen surface of a single shaker screen deck.

Abstract: A wellbore fluid may include an oleaginous continuous phase, one or more magnetic carbon nanoribbons, and at least one weighting agent. A method of performing wellbore operations may include circulating a wellbore fluid comprising a magnetic carbon nanoribbon composition and a base fluid through a wellbore. A method for electrical logging of a subterranean well may include placing into the subterranean well a logging medium, wherein the logging medium comprises a non-aqueous fluid and one or more magnetic carbon nanoribbons, wherein the one or more magnetic carbon nanoribbons are present in a concentration so as to permit the electrical logging of the subterranean well; and acquiring an electrical log of the subterranean well.

Abstract: A device and system applicable to separating components of a slurry is disclosed. The slurry can be a mixture of drilling fluid and drilling cuttings that can be separated with a separatory screen. A separatory tray can be disposed below an underside of the separatory screen. A pressure differential pan can provide fluid flow to a sump. A pressure differential generator can be located within the pressure differential pan and create a pressure differential between an upper side and a lower side of the separatory screen to enhance the flow of drilling fluid through the separatory screen.

Abstract: A system, an apparatus and a method for adjusting a weir control the rate and/or speed at which drilling fluid feeds a separator. Multiple separators are typically used in parallel to process fluid returning from the well. A distribution manifold directs fluid to each separator. The weir is positioned within a feeder on an inlet end of the separator and connects to an attachment plate within the feeder. The distribution manifold or other flow control mechanism operates in combination with the weir. Adjustment apparatuses control the height of the weir to determine the rate the fluid flows onto the separator. The adjustment apparatuses provide mechanical and/or automated operation of the weir. Various profiles of the weir and adjustments of the height of the weir within the feeder increase and/or decrease the speed of the fluid as the fluid spills into the separator.

Abstract: Methods of delivering a low density solvent into a wellbore include combining an oleaginous solvent and a nonoleaginous fluid to form an emulsion, and injecting the emulsion into a wellbore. Other uses of low density solvent systems may include dissolving waxes and wax-containing residues in a wellbore, on downhole tools, from sand screens, or use in general cleanup operations in and outside of the wellbore.
