After some anecdotal evidence, coupled with hard input from the new manufacturer of the machines, it was determined that the first generation units, manufactured by a company with little or no experience in oil field application, did not have the rigorous quality control measures or production specifications necessary to produce machines that were durable, reliable, and would function as intended in the field. The cost to retrofit and upgrade the original units to improve reliability was cost prohibitive. As a result of this realization, it was decided that the only way possible to properly test the technology would be to purchase and install new generation units. Due to the cost to purchase the new generation units, the older units were removed from service, placed in storage, and the project was terminated.
The operational problems were mostly related to the durability of the various components under oil field operating conditions such as inadequate mechanical, electrical, and electronic design for rough service, extended operation, and severe weather conditions. During the course of the demonstration project, it further appeared that the producing formation lacked sufficient reservoir energy and/or favorable oil properties to mobilize and displace oil from the formation into the well bore in order to recharge the oil column in the well. The BORS Lift units were then moved to a second lease which appeared to have more favorable WTI quality oil properties. Eight of these units were reported to have been installed and placed in operation on the second lease, however, operational difficulties continued. It was determined that the units were inadequately designed and would need to be replace by improved second generation units. Due to the lack of success with the first generation units and the extra cost to replace them with the redesigned units, the operators decided not to continue with the project and the project was terminated at that point.
Conclusions The first generation BORS Lift units as delivered from the manufacturer and used in this field demonstration project were not sufficiently durable enough for oil field production application. Although the technology was invented and developed by inventors who had some oil field experience, the units were manufactured by a manufacturer with no background or experience in oil field operations. The units did not have the rigorous quality control measures or production specifications necessary to produce machines that were durable, reliable, and would function as intended in the field.
Although the demonstration project produced little tangible results in and of itself, the lessons learned and the operational exp erience gained provided invaluable information to the inventors and to the succeeding manufacturer. Using the feedback and experiences from the field, following generations of BORS Lift units incorporated design changes and renovations which appear to have significantly improved their performance. Success of subsequent generation BORS Lift units in field operations has been reported by Regent Energy Corporation (Reference 1 , December 2001; reference 2, October 2001; and reference 3, September 2001), Rocky Mountain Energy Corporation (Reference 4, October 2002), and Renco Energy (Reference 5, April 2000; and reference 6, May 2000).
