In March of 1994, an Arbuckle well in the Bemis Shutts field was treated by Polymer Services, LLC. This well was drilled in 1941, and had been producing on a submersible pump, 12BOPD and 4750 BWPD from one foot of Open-Hole prior to treatment. Even at this rate, the well carried 2000' of fluid over the pump. A 2650 BBL Polymer treatment was designed for this well, and pumped continuously over a 3-day period. The well was returned to production on a beam pump for 86 BOPD, and 102 BWPD, pumped off. As a result of this job, power costs dropped from an estimated $6000 per month to approximately $600 per month, saving the operator at least $3237.50 in the last 48 months. Total cost for the work-over was estimated by the operator to be $35,000. Savings in the power costs alone paid out the total work-over cost in 7 months.

During the last 5 years, this well has averaged 23 incremental BOPD. The total incremental oil since the Polymer treatment is approximately 45235 BBL. At an average price of $15 per BBL this presents a total value of $678,525 in additional revenues for the operator, yielding a net profit of $643,525. Combined with the cumulative savings in power costs, the total value resulting from this successful polymer gel application $967,275. In conclusion, this single well treatment has yielded a 27-fold return on the Operators original investment.

The results from this treatment were unusual because the initial oil rate after treatment was somewhat higher than normal, and the results were sustained a longer period of time with very little decline in oil percentage. This can be attributed to the fact that a much larger than normal volume of polymer was pumped, which extended the depth of the area around the wellbore which was affected by the treatment. This well had an unusually large amount of moveable oil in place, which had simply been over-run by water coning and could not compete with the amount of water coming to the wellbore. The polymer treatment was able to selectively block the flow of water deep in the formation and allow the oil to drain much more efficiently.

This ELLENBURGER dolomite well was producing in excess of 300 barrels of water per day, with only 2-3 barrels of oil per day. Because this well had reached its economic limit, the operator called Polymer Services, LLC for a polymer treatment recommendation.

After a careful review of this well's history Polymer Services, LLC engineers designed and pumped a water-blocking polymer treatment designed specifically to correct the water-en-croachment problems found in this well. After a shut-in period of 5 days to allow proper development of gel-strength, the well was placed back on production.

After 30 days, the operator reported the well was producing 55 barrels of oil, and 12 barrels of water per day, and is running on its own gas, which was not the case prior to polymer treatment. THE OPERATOR REPORTED THE ENTIRE COST OF THIS WORKOVER HAD BEEN RECOVERED IN LESS THAN 20 DAYS, DUE TO THE ADDITIONAL OIL BEING PRODUCED.

Polymer Services, LLC has performed many of these treatments with a consistently high success rate (over 80%). If you have a well which you believe might benefit from a properly designed polymer treatment, please do not hesitate to call. We want to help you make the most of your existing reserves.

(Barber County, Kansas (July 1990)

This Mississippian Chert well had been producing at a rate of 750 BBL total fluid daily, with only 2-3 BBL of oil per day. Because this well had reached its economic limit, the operator called Polymer Services, LLC for a polymer treatment recommendation.

After a careful review of this wells history, Polymer Services, LLC engineers designed and pumped a water-blocking polymer treatment designed specifically to correct the water-encroachment problems found in this well. After a shut-in period of six days to allow proper development of gel-strength, the well was re-started. After 90 days, the operator reported the well was producing 24 barrels of oil, 120,000 mcf of gas, and 40 barrels of water daily.

Eight years later, this well continues to produce at a rate of 10 BOPD, 80 BWPD, and 100 mcf of gas. The total incremental oil since the polymer treatment is 34600 BBL. Incremental gas total to date is 321000 mcf.

During the last eight years this well has pumped an average of 15 BOPD at an average oil price of $15.00 Per BBL and 100 mcf at a gas price around $2.00 per mcf. This yields an average of net profit of $1,161,000.00. This treatment also saved our client $750.00 per month on lifting costs, resulting in a total savings of $72,000.00 This work over paid out in less than 3 months.

• Excessive water production average well producing 4500-5000 BWPD

• 12-17 BOPD

• 2000' Fluid Over Pump (PFL)

• High Electricity Costs =/- $6000/month per well

• Disposal wells at maximum capacity

• Many wells shut in due to lack of disposal capacity / high lifting costs.

• Under "Plug or Produce" orders from corporation commission.

• Polymer water shut-off gel treatments were designed & pumped on 4 producing wells initially.

• Average treatment size was 1150 BBl Permblock - 3025 Polymer gel.

• Shut in well treatments were performed when disposal capacity allowed, after producing wells had been treated and placed back on time.

• Average water production per well was reduced 75 - 90%

• Daily oil rate (BOPD) per well either remained in the 12-17 BOPD range, or increased significantly.

• Average electricity savings is $3500/month per well.

• In most cases, a 180HP submersible pump was replaced with 60-75 submersible pumps.

• 2 wells are on beam pump/pumped off.

• Average daily oil rate for the field has increased by 90 BOPD
