Zimmerman Butte area
Wyoming, 2012-2013

Zimmerman Butte:

  • Production 400 BOPD
  • Total production to date: 1,200,000 barrels
  • Producing Formation:
    • Phosphoria
    • Sandstone
  • Average of 100,000 barrels EUR of oil per well
  • Strong water drive resulting in 30%+ recovery per spacing unit
  • IP’s often greater than 400 BOPD with relatively steep decline
  • Field Currently at 23% recovery

BERO treated 8 wells in Wyoming on May 2012-Apr. 2013.Take one of them for example, the result shows below:

The well shows base oil increased from 4 BOPD to 11 BOPD, Water decreased from 90 BWPD to 47 BWPD.

The analysis result shows that the main reason for decrease of production is the plugging of the near-wellbore area by organic matters such as wax and asphalt contained in crude oil. In April 2012, BERO™ biosurfactant was mixed with formation water and injected in the well to remove plugging and stimulate production and the temperature of the injection fluid was above 122℉. During construction, pressure rose from 0 psi to 1450 psi.

After shut-in for 5 days, it resumed production and then its production greatly increased. Its daily oil production increased from 4 BOPD to 11 BOPD and water production decreased from 90 BWPD to 47 BWPD.

Oakland Oil area
Oklahoma, 2011-2012

Some well on the Mcclain county, Oklahoma is owned and operated by OakLand Oil. This well was originally drilled by Oakland oil in 1997 and has cumulative production (thru 3-31-12) of 108,421 bbls of oil (34°API gravity).

The well has declined (2009 thru 2010) to ~ 3 BOPD. Early in 2011 prior to treating with BERO™ fluid, the well was shut in for 45 days. The production history on page 3 shows an increase in production after the well was acidized and returned to production. This is accompanied by a fairly precipitous decline. As indicated, the well averaged 4.34 BOPD for 9 days prior to BERO™ fluid treatment.

The well was shut-in for 5 days after treatment with BERO™ fluid on 5-31-11.Production was resumed on 6-6-11.It showed a clear and sustained increase in production after treatment with BERO™. Peak average monthly production of 8.81 BOPD in October 2011 was double the average production of 4.34 BOPD prior to treatment. Additional oil produced in 2011 and 2012 showed a good increase over pre-BERO™ treatment levels. Earlier production levels in 2010 make additional oil produced even higher.

 

Bruce buckle Seoul area
Texas, 2009-2010

In March 2010, we applied BERO™ treatment for an oil well located at Blue button area, Texas State. The Company possesses concession covering an area of 420,000 acres and involving 352 oil wells in Maverick County, Dimmit County and Webb County.

The 8 oil wells which were applied BERO™ treatment to remove plugging are located at Blue button area. The analysis result shows that the main reason for decrease of production is the plugging of the near-wellbore area by organic matters such as wax and asphalt contained in crude oil. Full plugging removal is conducted according to the production need and the requirements of geological solution of these 8 oil wells. The injection of BERO™ biosurfactant as the plugging removal agent can lower water cut, stabilize oil and control water cut and stimulate the production of crude oil. Take one of them for example, the result shows below:
