Abstract: A screen intake apparatus for a water intake system uses a cleaning system to clean one or more screen intakes. To clean debris from a screen, pipes in the interior of the screen receive pumped liquid (e.g., water or incompressible liquid) from a pump. Outlets, such as apertures or nozzles, on the pipes then direct the pumped liquid into the interior of the screen. One or more valves can vary, agitate, or pulse the flow of pumped fluid and/or can selectively deliver the pumped liquid to the pipes to remove collected debris from the exterior of the screen. A heater of the system can also heat the pumped liquid for delivery to the pipes to remove or prevent ice formation on the screen.

Abstract: Systems and methods for de-watering waste drilling fluid. In some embodiments, the de-watering system includes a drilling fluid reclamation system receiving the waste drilling fluid from a wellbore and removing at least some solids from the waste drilling fluid, a manifold combining the waste drilling fluid from the drilling fluid reclamation system and organic polymers, whereby an aggregated mixture of solids in the waste drilling fluid and water are formed, and a centrifuge receiving the aggregated mixture and separating the solids from the water in the aggregated mixture, whereby solid drilling fluid waste and substantially colloidal-free water are formed.

Abstract: A drilling fluid degasser having a weir to more evenly spread the drilling fluid over the leaves of the degasser to increase the efficiency of the degasser is disclosed. Additionally, a plurality of gas vent pipes are provided that ensure that once the gases are removed from the drilling fluid, the gases are removed from the degasser without contacting the drilling fluid to ensure the gases are not mixed into the drilling fluid again.

Abstract: A multi-functional linear motion shaker includes a rectangular outer support frame with a tank, often referred to as a "possum belly", for receiving the incoming drilling fluid flow. A set of adjustable louvers and a tray is positioned on the side of the tank. The adjustable louvers and tray serve to screen out the larger and stickier drill cuttings or solids. A vibrating deck assembly is positioned within the outer support frame adjacent the tank and tray assembly. The vibrating deck assembly is of a double deck design whose upper and lower decks include cross members to support the mud screens. The upper and lower decks are vertically spaced apart and connected together into one unit by vertical structural members. A moveable plate is positioned on the upper deck adjacent the adjustable louvers and tray. This moveable plate can be positioned to direct drilling fluid flow to the upper deck or repositioned to redirect fluid flow to the lower deck and bypass the upper deck.
