Specifications

OVERVIEW

When the pressure in an oil reservoir is depleted to the point where the well will no longer flow, some artificial means of lift must be used to bring the oil to the surface. The most generally accepted means of artificial lift is the subsurface sucker rod pumps, actuated by a pumping unit. There are 2 basic types, the Tubing Pump and the Insert Pump:

TUBING PUMP

The tubing pump barrel is threaded directly onto the bottom of the production tubing, and is installed near the bottom of the well immersed in the oil within the well casing. The plunger is run into the tubing on the sucker rod string. Generally a standing valve puller is run between the bottom of the plunger as well as the separate standing valve. This makes the removal of the standing valve optional when pulling the sucker rods and the plunger. The plunger, travelling valve, and the standing valve can be serviced simply by pulling the rods, but it requires removal of the tubing to service the pump barrel.

INSERT PUMP

An insert pump is run into the well in the rods as a complete unit. A seating assembly on the pump engages a seating nipple on the tubing when the pump is run in, or installed. After the well has pumped up, the additional pressure of oil in the tubing combined with the flow line pressure holds the pump firmly in place. The entire rod pump is removable, and therefore may be serviced merely by pulling the sucker rod string.
