Q2-3 well, the reason of decreasing oil production is that the high wax in crude oil near wellbore resulted in plugging after analysis.We carried out BERO treatment on Q2-3 well, mixed with formation water. The temperature of the injection fluid above 50 ℃.Pressure in the process of construction increased from 0 psi to 1450 psi. Q2-3 well was in close well to resume production in 5 days.Q2-3 shows base oil from 3.9 BOPD to 8.8 BOPD.

Application of BERO™ Biosurfactant in Qinghai Oilfield and Its Effect (3)
14 wells in of Qinghai Oilfield Company, the reason of decreasing oil
production is that the high wax in crude oil near wellbore resulted in plugging
after analysis. BERO™ biosurfactant can efficiently release hydrocarbon (oil)
on the surfaces of solid particles. It is a non-acidified preparation and will not
cause secondary pollution of reservoir or disturb crude oil dehydration and
sewage treatment systems and can prevent secondary plugging since it
produces no other new product during reaction. We had BERO treatment for
these 14 wells from October 2005, and removed organic plugging of these
wells effectively.
Q2-3 well, the reason of decreasing oil production is that the high wax in crude
oil near wellbore resulted in plugging after analysis. We carried out BERO
treatment on Q2-3 well, mixed with formation water. The temperature of the
injection fluid above 50 ℃.Pressure in the process of construction increased
from 0 psi to 1450 psi.
Q2-3 well was in close well to resume production in 5 days.Q2-3 shows base
oil from 3.9 BOPD to 8.8 BOPD.
