DPS Microbial Solutions bacterial treatments are a monthly maintenance program. The bacteria is usually injected down the backside of the wellbore; with the well being left shut in for at least 24 hours. During this time the bacteria will seek out its food source(skin damage), attach to the source, and begin the breaking down of the skin damage, After 24 hours, the well is put back into production and over the period of a month, the DPS bacteria are produced out of the wellbore with the fluid.
