Abstract: In drilling into a subterranean formation, several factors influence the rate of penetration, including, but not limited to, the type of formation being drilled, the weight on bit, and the rotational speed of the drill bit. Disclosed are a system and method for controlling the rotational speed of a drill bit based on regulation of fluid flow to the motor driving the bit, while maintaining at least a minimum flow of fluid to the annulus to clear debris from downhole during drilling. Regulation of fluid flow to the motor and to the annulus may be accomplished utilizing a flow diverter configured to adjust a flow ratio depending on drilling conditions in order to maximize efficiency of the motor downhole during drilling.

Abstract: A fluid choke may include a housing and a shuttle configured to move within an interior chamber of the housing. The housing may have a fluid inlet channel and a fluid outlet channel. The shuttle may have a gate connected to an end of the shuttle and the gate may be configured to mate with a seat located in the housing at the fluid outlet channel. The shuttle may be moved within the interior chamber by a pressurized hydraulic fluid configured to apply a hydraulic pressure to a peripheral portion of the shuttle, an inner portion of the shuttle, and the gate.

Abstract: A system for filtering particles from a fluid includes a strainer. The strainer includes a housing having an inlet, a first outlet, a second outlet. A filter element is positioned in an internal volume of the housing. The filter element defines a bore formed axially-therethrough and openings that are substantially transverse to the bore. A first portion of the fluid that enters the housing through the inlet flows through the openings in the filter element and exits the housing through the first outlet, and a second portion of the fluid that the housing through the inlet bypasses the openings and exits the housing through the second outlet.

Abstract: Apparatus and vibratory separators having a base, a separator housing movably connected with the base, the separator housing including a top having an inlet chute, a bottom having a liquid discharge chute, a cylindrical sidewall defining an axial centerline and having a discharge spout, and at least one screen mounted within the separator housing. A vacuum system proximate the at least one screen may also be incorporated. The apparatus further includes at least one circular force generator (CFG) disposed on the separator housing, and at least one sensor positioned on the apparatus for measuring an operating function associated with and enabled by the vibration profile, and a controller in electronic communication with the sensor and with the at least one CFG. The difference between the measured operating function and the prescribed operating function is reduced. The apparatus may also include at least one CFG having a plurality of imbalanced masses which rotate in a plane parallel the axial centerline. The CFG may be disposed in an annular ring arrangement on the top, on the bottom, or CFGs disposed on both the top and the bottom.

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.
