Abstract: A transportable drilling fluid cleaning system for removing solids from drilling fluid at a drill site comprises a platform for transporting the system. A bin region on the platform retains solids from the drilling fluid. A settling tank on the platform separates the drilling fluid into an upper fluid fraction having a reduced concentration of solids and a lower solids fraction having a higher concentration of solids as the drilling fluid flows from an inlet chamber for receiving drilling fluid to at least one other chamber. A stand on the platform supports at least one centrifuge for separating the solids from the drilling fluid, the stand being movable between stored and operating positions. The system provides a self-contained unit that is easily transportable on a flat bed truck to provide all the ancillary equipment necessary for solids control at the drill site.

Abstract: An embodiment of the invention is an automated system for transporting and deoxygenating a solution. The system is designed to: 1) transport a solution through a deoxygenating device 2) continuously monitor the oxygen content of the deoxygenated solution 3) collect the solution in a reservoir and automatically maintain solution level 4) automatically dispense the solution as requested and 5) perform automated solution prepare, startup, and shutdown operations.

Abstract: A downhole liquid and gas separator system has a pump, a separator and a motor, and a shroud around the pump, separator and motor. The shroud has a lower impermeable portion with a closed lower end and an upper porous portion. The upper end of the impermeable portion is above the inlet port for the separator so that production fluid flows upwards between the well casing and the shroud, over the upper end of the impermeable portion and downwards to the inlet port, generating a pressure drop and releasing gas before the production fluid enters the separator.
