Summary of Testing of Variable Slippage Pump (VSP) For Gas Locking Conditions In Down-Hole Sucker Rod Pumps
Presenters
Benny Williams, Harbison-Fischer
The Harbison-Fischer Variable Slippage Pump, (VSP), has been field tested since December 1999 in wells located primarily in West Texas and New Mexico. Results have been favorable in gas locking conditions by eliminating gas locking, and increasing gas production in some wells. This paper will review the test data and the characteristics of these wells. It will also describe the fundamentals of this method of artificial lift, and present what was learned about pump component selection and downhole applications.
