Greater Midwest Oil - Field Trial Results   >>

 |  Cyclic Microbial Injection  |  MEOR/MIOR Field Flood  | 

One of RAM's most successful case histories is the 9-well Osborn lease located in Hamilton County, Illinois which produces from the Tompsonville Pool formation. Two wells on the lease (the #2 and #4 Osborn) had a history of heavy paraffin build-up which required frequent workovers (pulling and steam cleaning the rods). Both wells were treated for paraffin problems on 11/15/1990 with 1/2 drum (27 1/2 gallons) of Wel-Prep 5.

Normally, the #2 and #4 wells combined would have required 3 to 4 workovers during the field trial period. Neither well required a workover during the entire field trial period. Additionally, and quite unexpectedly, the Osbourn #2 developed substantial gas pressure where none had existed before.

Pre-treatment oil production for the #2 and #4 wells averaged 2 BOD and 3 BOD respectively; post-treatment production increased 100% to 4 BOD and 6 BOD.  Although no unusual maintenance was performed on this lease during the the field trial, total lease production which had averaged 10 BOPD pre-treatment increased to 20 BOPD in the immediate post-treatment period. Total oil production from the Osborn lease was still holding at 18 BOPD as of 6/15/1991 - the last date that data was available from the producer.

Total WP-5 treatment costs were approximately $800. Payout took 17 days calculated as follows:

Net return per barrel of incremental oil produced = $8.00 ($19.00 Avg. Price per Barrel - $11 lifting costs)

 7 days to recover 70 barrels of oil not produced during the week-long shut-in period
10 days to recover the $800 treatment cost (10 BOPD incremental oil x 10 days = 100 x $8.00 net = $800)

As of 6/15/1991, the last day that field data was available, the lease was $14,500 ahead on increased oil production and had saved approximately $6,000 on what would have been normal workover costs for paraffin build-up. Unfortunately, the declining price of oil forced the producer into bankruptcy and no additional MEOR treatments were made on any of their producing well.
