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 11 wells from may 2006, and removed organic plugging of these wells effectively. D1-4 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 D1-4 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. D1-4 well was in close well to resume production in 5 days.D1-4 shows base oil from 2.4 BOPD to 4.1 BOPD.
