XSTNG NBALANC 1 PRCNT PRODUCTON POTNTAL The results of the pumping fluid level test indicate approximately 337 meters of pump submergence. A pump intake pressure of 2828 kpa was determined from these results using an estimated annular fluid gradient of 6. kpa/m. Based on these results additional production may be available from the well. GNRAL COMMNTS The pump card indicates very good efficiency with slight losses due to tubing movement (tubing is unanchored). The valve checks indicate that the bottomhole pump is in excellent mechanical condition with only a slight amount of travelling valve leakage and/or plunger slippage. RCOMMNDATONS f a more accurate calculation of the pump intake pressure is desired to determine the amount of available productivity, an annular fluid depression test and inflow performance relationship study should be conducted. f the existing gearbox torque (17% of rating) cannot be tolerated, a reduction in pumping speed of approximately.5 SPM would be required. A complete system re-design should be considered to maintain or increase production levels without experiencing any equipment overload. When the well is next serviced, consider installing a tension type tubing anchor to eliminate efficiency losses and equipment wear due to tubing movement and extend the life of the equipment. Counterbalance requirements should be re-evaluated following any changes to equipment or operation.
