Inserted Configuration Downhole Sucker Rod Pump Description

A downhole Sucker Rod Pump is used on onshore sites to create a mechanical lifting motion. This motion is created by a series of valves, plungers, rod strings and rods that are assembled together as a pumping system. A Sucker Rod Pump works in the following way:

• A motor and gear box runs the power shaft.
• Counter weights are added to the cranks at the end and the cranks lift the counter weights.
• The Pitman arms connect the walking beam with the cranks. The beam then hinges and lowers the plunger. When the plunger and the horse head are lowered, it completes 1 downstroke.
• When the horsehead and plunger are lifted up, the fluid gets lifted from the bottom to the surface. This completes the upstroke.
• The fluid flow determines the opening and closing of the valves. The standing valve is opened while the riding valve is closed during the upstroke. During the downstroke, the standing valve gets closed and the riding valve is opened.

The complete API designation includes the following:

• Nominal tubing size (from 1.9- to 4.5-in. OD) - represented with 2 digits
• Basic bore diameter (from 1.0625 to 3.75 in.) - represented with 3 digits
• Type of pump (rod or tubing) - R or T to indicate type
• Type of barrel (heavy, thin, or X type) - single alpha character to represent the barrel type
• Seating-assembly location (top or bottom) - A (for top), B (for bottom), or T (for bottom, traveling barel)
• Type of seating assembly (cup or mechanical) - C or M to indicate type
• Barrel length (ft) - single digit length
• Nominal plunger length (ft.) - single digit length
• Length (in.) of upper extension (if required)- single digit length
• Length (in.) of lower extension (if required)- single digit length
