Abstract
The subject invention provides microbe-based products, as well as their use to improve oil production and oil transmission and refining by, for example, remediating the disposable layers in oil tanks and other oil storage units. The subject invention can be used to remediate a sludge layer and/or other dissolved solid layers that form in oil storage tanks. Advantageously, the subject invention can decrease the cost of mechanical remediation of disposable layers, and aid in the recovery of more pure hydrocarbons from crude fluids.
