Reducing Tubing Failures in the Tambaredjo Field, Suriname

May 31, 2015  In the period from 2008 to 2012, an annual average of 580 downhole failures occurred, 54% of which were caused by tubing leaks. In an effort to reduce these tubing failures, a pilot program was commenced to install rod guides in wells with the highest failure rate and to install a 25-ft sucker rod directly above the pump.

The downhole card calculations include gross pump stroke, fluid load, and pump inlet pressure. The pumped fluid, calculated from the downhole stroke, is one of the more accurate methods of determining well production. Gross differences between this and the well test are a good indication of a tubing leak, pump malfunction, or bad well test.

Downhole Rod Pumps - NOV

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 flowline pressure holds the pump firmly in place. The entire rod pump is removable and therefore may be serviced by pulling the sucker rod string.
