    Abstract: A wellbore formation fluid pump (30) and downhole safety valve system (20) includes a wellbore formation fluid pump (30) operable by a motor for lifting fluid entering the wellbore to the surface. A hydraulic fluid pump (10) is operably connected to the wellbore formation fluid pump (30). The hydraulic fluid pump (10) is configured to produce a selected fluid pressure sufficient to open a hydraulically operated wellbore device (20) when the wellbore formation fluid pump (30) is operated at at least a threshold rate. The hydraulic fluid pump (10) has a least one backflow feature (10C, 10D) to enable automatic stopping of operation of the hydraulically operated wellbore device (20) when the wellbore formation fluid pump (30) is operated below the threshold rate.

    Abstract: A pump fluid end includes a body that defines a plunger bore and a working fluid bore that intersects the plunger bore to form a cross bore. A packing bore is defined in the plunger bore and includes a packing sleeve bore, a taper relief bore, and a transition bore. The packing sleeve bore transitions to the taper relief bore at a radial shoulder and the taper relief bore transitions to the plunger bore across the transition bore. The transition bore extends between an external corner contiguous with the plunger bore and an internal corner contiguous with the taper relief bore and at least one of the external and internal corners is rounded and exhibits a radius. The packing bore is treated with a surface pre-stressing treatment.

    Abstract: The present disclosure relates to passively rotating a valve using fluid flow. Some aspects may involve a valve including a body, a lower stem, and vanes. The body may include a bottom portion that can be positioned with respect to a seat for preventing fluid flow when the valve is in a closed position. The lower stem may extend axially from the bottom portion of the body to position the bottom portion with respect to the seat. The vanes may extend from the body and be responsive to the fluid flow while the valve is in an open position such that the valve and the lower stem rotate with respect to the seat.

    Abstract: Various methods for detecting and accounting for the effects of half-stroking by a pump are provided. In one embodiment, a method includes operating a pump of a downhole tool to pump fluid from a formation through the downhole tool and determining pressure differentials between a formation pressure and pressure of the fluid within the downhole tool. The pressure differentials for each of a forward stroke and reverse stroke of the pump can be summed and then compared to enable identification of onset of half-stroking by the pump. Additional systems, devices, and methods are also disclosed.

    Abstract: Method and apparatus overcoming gas-lock in reciprocating downhole pumps. On the downstroke of a plunger in a barrel, gassy fluid is compressed in the pump chamber between standing and travelling valves. Downhole plunger movement drags a sleeve over a mandrel for opening a chamber valve to a staging chamber located at a downhole end of the travelling valve for receiving at least a portion of the compressed and gassy fluid therein. On the upstroke, the chamber valve is dragged closed for sealably retaining the compressed gassy fluid therein while drawing an additional increment of fluid through the standing valve into the pump chamber. Continued downstroke and upstroke cycles increases pressure of the compressed gassy fluid in the pump chamber until it exceeds the hydrostatic head above the travelling valve for resumption of normal fluid pumping.
