This paper will present the results of the last down-hole-rod-drawn pump fluid slippage testing recently completed at the Texas Tech test well (Red Raider #1). This is # 4 in the series which began with laboratory testing presented in 1998. This paper will present an update to the empirical equation which will estimate down-hole fluid slippage over a range of pump sizes, clearances and strokes per minute (SPM).
