Application of BERO™ Biosurfactant in Texas and Its Effect
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.
Within 3 months after injection, the daily crude oil production of 4 oil wells
increased by 3 times and that of 4 oil wells increased by 2.4 times on average.
As for Well Lambert 2, the analysis result shows that the main reason for
production reduction is the plugging of the near-wellbore zone caused by
organic matters such as wax and asphalt contained in crude oil. In March 2010,
BERO™ biosurfactant was mixed with formation water and injected in Well

Lambert 2 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, Well Lambert 2 resumed production and then its
production greatly increased. Its daily oil production increased from 4 BOPD to
17 BOPD and waterproduction decreased from 60 BWPD to 46.9 BWPD.
As for Well Marsters 5, the analysis result shows that the main reason for
production reduction is the plugging of the near-wellbore zone caused by
organic matters such as wax and asphalt contained in crude oil. In March 2010,
BERO™ biosurfactant was mixed with formation water and injected in Well
Marsters 5to 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.
