摘要： A system for use with a subterranean well can include a fluid oscillator which discharges pulsating fluid from a tubular string in a direction at least partially toward an end of the tubular string proximate a surface of the earth. A method can include discharging a fluid from the tubular string, thereby applying a reaction force to the tubular string, which reaction force biases the tubular string at least partially into the well. Another method can include discharging a pulsating fluid from a fluid oscillator in a direction at least partially toward an end of the tubular string, and drilling into an earth formation with a drill bit connected at an opposite end of the tubular string in the well.

摘要： A transmissionless variable output pumping unit comprising a multiple crankshaft pump driven by a prime mover. The apparatus includes an adjustment mechanism for adjusting a phase angle between first and second crankshafts. Plungers in the pump are disposed in cylinders forming part of a pumping chamber. When the phase angle is at a minimum, the plungers operate together for maximum discharge from the pump. When the phase angle is at a maximum, the plungers operate substantially opposite one another for zero discharge. The phase angle may be infinitely adjusted between the minimum and maximum.

摘要： A device for separating constituents of a fluid mixture includes an elongate vessel oriented at an acute angle to horizontal. The vessel is operable to receive the fluid mixture and direct the fluid mixture to flow in a convection cell spanning substantially a length of the vessel. The convection cell is formed by gravitational forces acting on the fluid mixture and is operable to deposit a heavy constituent of the fluid mixture about a lower end of the vessel and a light constituent of the fluid mixture about an upper end of the vessel.
