Abstract: Various embodiments of the present disclosure provide methods of making wellbore fluids with enhanced electrical conductivities. In some embodiments, such methods comprise: (1) pre-treating a carbon material with an acid; and (2) adding the carbon material to the wellbore fluid. Further embodiments of the present disclosure pertain to wellbore fluids formed by the methods of the present disclosure. Additional embodiments of the present disclosure pertain to methods for logging a subterranean well by utilizing the aforementioned wellbore fluids.

Abstract: Described herein are splitters for holding and distributing input material to one or more decks of a gyratory sifter, where the splitter distributes approximately an equal amount of input material to each deck. An exemplary splitter may include a bottom surface, a sidewall, and one or more openings through the sidewall. Each opening may include a plurality of slits, allowing input material to pass therethrough. Where multiple openings are provided through the sidewall, the openings may be evenly spaced and have an equivalent area. The bottom surface may be substantially circular, and the sidewall may extend perpendicularly from the edges of the bottom surface. An exemplary splitter may be able to receive and distribute the input material when a gyratory force acts on the gyratory sifter on which the splitter is installed.

Abstract: A modularly segmented apparatus for precise borehole pressure control, removing waste from borehole fluid, and recirculating the cleaned borehole fluid includes a pressure control section, a gas separator section, and a waste management section. In the pressure control section, a pressure manifold interconnects a plurality of chokes. A plurality of valves are used to direct the contaminated fluid through one of the chokes, which maintains a precise and predetermined pressure in the system. The manifold, chokes, and valves are mounted on a skid for easy transport. In the gas separator section, a gas separator is used to remove a majority of the gases present in the contaminated borehole fluid. In the waste management section, a vibratory separator removes large solid contaminants from the degassed fluid. The solids are directed to a solids collection container for further treatment or disposal. The fluid is directed to a first pit, which may be one partitioned are of a larger collection tank.

Abstract: A method of cleaning a wellbore prior to the production of oil or gas, wherein the wellbore has been drilled with an invert emulsion drilling mud that forms an invert emulsion filter cake is disclosed. The method may include circulating a breaker fluid into the wellbore, where the breaker fluid includes a non-oleaginous internal phase and an oleaginous external phase, where the non-oleaginous phase includes a water soluble polar organic solvent, a hydrolysable ester of a carboxylic acid, and a weighting agent, and the oleaginous external phase includes an oleaginous fluid and an emulsifier, and where the hydrolysable ester is selected so that upon hydrolysis an organic acid is released and the invert emulsion of the filter cake breaks.

Abstract: A method and apparatus of removing drill cuttings from an oil and gas well drilling platform includes the steps of separating the drill cuttings from the well drilling fluid on the drilling platform so that the drilling fluids can be recycled into the well bore during drilling operations. The cuttings are then transmitted via gravity flow to a materials trough having an interior defined by sidewalls and a bottom portion. The drill cuttings are suctioned from the bottom portion of the trough interior with a suction line having an intake portion that is positioned at the materials trough bottom. Drill cuttings are transmitted via the suction line to a pair of hoppers that each have an interior. A vacuum is formed in sequence within the interior of each hopper using a blower that is in fluid communication with the hopper interiors. The two hoppers are positioned one above the other so that cuttings can be added to the first, upper hopper via the suction line and then fed by gravity to the second, lower hopper.
