Paper presented at the SPE Artificial Lift Conference-Americas, May 21–22, 2013
Paper Number: SPE-165039-MS
... the traveling valve in the closed chamber does not overcome the weight of liquid column lying above the traveling valve in the pump barrel. This fails to lift the ball off the seat. This paper brings forth the design of a Sucker Rod Pump consisting of a solenoid actuated hydraulic valve in the traveling...

... of the traveling valve ball is greater than the pressure exerted on the pump chamber side of the traveling valve at the bottom of the down stroke. On the upstroke the gas expands in the pump chamber but the pressure in the chamber remains above the pump intake pressure and the standing valve does not open. So...

... and a traveling valve. The plunger is lifted by a prime mover, which is connected to the plunger via a string of sucker rods (Figure 1). The traveling valve is forced closed and the standing valve is drawn open at the start of the upstroke of the plunger. Fluid is drawn from the wellbore into the pump barrel...

... pumps. The term gas lock often is used to describe any gas problem in a sucker-rod pump. Surface-valve checks and dynamometer-card analysis cannot distinguish between various gas problems. True gas lock exists when the hydrostatic pressure above the traveling-valve ball is greater than the pressure...

The system operates under a reciprocating motion transferring the hydraulic loads between the standing valve and the traveling valve. On the down stroke the traveling valve is open and is filling the barrel placing the load...

... are common problems in sucker rod pumps. To alleviate these problems, it is a common practice in the oilfield to "bang bottom" to unseat the traveling valve. The action of "banging bottom" may solve the gas locking and sticking problems, but it also causes undesirable impact and wear on the pump, sucker...

..., the well will be overpumped and a pumped-off or fluid-pound condition will occur. When the liquid production from the well is inadequate to fill the pump barrel completely on each suction stroke, the barrel will be partially filled with free gas. As the pump plunger starts downward, the traveling valve...
