LEARNING IN TEXAS DELAWARE ROD PUMPING EXPERIENCE

Oxy Resources established the Texas Delaware Team in April 2013 when ~200 wells were purchased in the area of Pecos, Texas.  These primarily vertical wells produce from various commingled Delaware intervals located at 8,000’ to 12,000’ deep. The nature and deviation of these wells have made rod pumping them challenging and failure frequencies have been as high as 1.5 failures/year. Many lessons have been learned in driving the failure frequencies down to the current level of 1.0 failures/year. This paper will share some of the lessoned learned using various equipment types including fiberglass COROD, Poly-keytone Lined Tubing,  Poly-keytone Rod Glides, and Variable Slippage Pumps.
