COMMENTS AND RECOMMENDATIONS
- The analysis report above shows that the pumping unit gearbox is overloaded (135-140% depending on the card selected). As is, a counterbalance adjustment would reduce the degree of overload considerably – in the case above, down to 14%. Best solution to the overload is to move the stroke length to the middle hole and, if possible, reduce the current motor sheave diameter.
- Well will displace approximately 100 B/D total fluid at 80% pump efficiency with current pump size, SPM, and stroke length. If “normal” total fluid production is 30 B/D, well should only be pumping 7-8 hours per day. Erratic inflow may require longer daily runtime to maintain maximum production.
Using a grade “D” rod string, maximum stress is 80% - using a “Service Factor” of “1”.
- Pumping unit structure (24,600 lbs.) is 87% loaded.
The calculated downhole pump cards show that well is pumped off --- very badly so at times. Very slight gas compression noted.
-TAC appears to be holding OK.
LiftAdvisor – Dedicated Analyst
• One of our well analysts is assigned to the companies wells
• Using their experience and our software they will look for problem wells or issues that might create problems later
• Customers can also use the allotted time to have the analysts look at wells they have concerns about
• The goal of this service is to be proactive in identifying problems before they become too costly
LiftAdvisor – Target Customers
• Independents with contract pumpers
• Companies that do not have the available resources to take full benefit of LOWIS
• Companies that have to potential to become LOWIS customers but need to prove the technology (short term-long term approach)
