Abstract: A method of producing hydrocarbon fluids from a wellbore. The method comprises providing a wellbore, with the wellbore having been completed with a tubular string along a horizontal section. The tubular string may be a string of production casing, or joints of slotted tubular bodies. The method also includes running a fluid pumping system into the wellbore. The fluid pumping system comprises a sucker rod string, a traveling valve residing at a lower end of the sucker rod string, and a standing valve releasably connected to a lower end of the traveling valve. The method additionally includes landing the standing valve into a seating nipple along the horizontal section of the wellbore, and then releasing the standing valve from the traveling valve while the fluid pumping system is in the wellbore. The method further includes operating a pumping unit at a surface to produce hydrocarbon fluids from the production casing.

Abstract: A standing valve puller is provided. The standing valve puller is configured to latch onto an engagement pin when the engagement pin is run into the standing valve puller within a wellbore, downhole. The standing valve puller generally includes a tubular housing having an upper end and a lower end. The upper end comprises a pair of pivoting arms dimensioned to receive the engagement pin, while the lower end offers a threaded connector that connects to a standing valve. When the engagement pin is lowered through a through-opening preserved within the arms, the arms pivot to latch onto the engagement pin. When the engagement pin is lowered again, the arms pivot away from the engagement pin, providing a “latch and release” cycle. A method of unseating a standing valve from a seating nipple in a wellbore is also provided herein.

Abstract: A method of pumping fluids down a wellbore. The method first comprises providing a wellbore. The wellbore has been completed with a pumping system comprising a string of production tubing, a polished rod, and a sucker rod string extending down into the production tubing. A traveling valve is connected at a lower end of the sucker rod string. The method also includes adjusting a position of the polished rod relative to the pumping system to enable the traveling valve to tag a standing valve. The method further comprises compressing the traveling valve to cause the traveling valve to open. The method additionally includes pumping a fluid down the production tubing. The fluid is further pumped across the traveling valve and the standing valve, optionally while the standing valve remains seated.
