A large oil field comprised of 1200 rod-pumping oil producers with the objective to reduce failure frequency. We picked twenty-five of the worst
performing wells and installed them with the TSR/SJ equipment from 1996 to 1998. Results indicating significant improvements can be seen below.
The average run time between failures was improved from 1.5 months (8 month average) to 6.1 months per well (48 month average) with further improvement to 9 months per well 1 year after installation.
This improvement yielded a 100% rate of return and a 3 month payout. In addition, this 76% reduction (4.1 times the life) is for all failure types (not just wear-related, but also includes rod parts, stuck pumps, etc.).
One could assume that the TSR could extend the life between failure repairs by 4 to 6 times. The savings generate around 40% to 100% rate of returns for wells that fail at least once every two years or more often (assuming the TSR cost is equal to one repair cost).
