Kansas Lift cost reduction

Key Well Information
Problem Statement – High paraffin from the oil reservoir was causing problems with the surface tubing and fluid lines resulting in 2 hot oil treatments per month. Each hot oil treatment required 30 to 40 barrels of flush oil resulting in delays for oil recovery. Hot oiling over time plugs up the formation because the paraffin melts and goes downhole.

United Energy Solution – Continuous injection at 500 PPM of K-line product KH-30 to disperse the paraffin at the reservoir and at the well surface to maintain well equipment and avoid hot oil treatments.

Below is a table of the tangible individual well costs and benefits for the project. From May 2005 until October 2005 we have brought on 16 wells in total. The results average $8,367 tangible savings per well for a total of $133,865. This is not considering the elimination of well downtime required to pump the flush production. In addition as more and more wells are treated with KH-30 we expect to see strategic benefits beyond the well operations.

Trinidad – CO178

Below is an example of our first well in Trinidad with Petrotrin SF. The initial results are outstanding bringing the well production beyond its historic maximum of 20 BPD. The well is now producing steady 29 BPD and before was only producing 3 BPD because of the high paraffin sludge content.

Solution Blended 4 drums of KX-100 with 4 drums of diesel and then followed that
with 16 drums of diesel and 8 drums of light crude oil. The well was shut in
for 48 hours, and it was then put back into production.
