Hydraulic pumping system for use with a subterranean well |
| abstract |
A hydraulic pumping method for use with a subterranean well having a rod string connected to a downhole pump includes displacing the rod string in response to pressure applied to a hydraulic actuator by a hydraulic pressure source connected to the hydraulic actuator. The hydraulic pressure source includes an accumulator. Pressure in the accumulator is automatically regulated in response to measurements of the pressure applied to the hydraulic actuator. |
