Method of controlling scale in oil recovery operations
Abstract
Disclosed is a method of producing highly viscous minerals from a subterranean formation by injection of an acidic, thermal vapor stream without substantial scale buildup in downstream piping, pumps and well bore. The process comprises heating the formation by injection of heat, preferably in the form of a thermal vapor stream composed of combustion gases and steam and injecting an acidic compound simultaneously with the thermal vapor stream into the formation at a temperature above the dew point of the thermal vapor stream. The acidic, thermal vapor stream increases the solubility of metal ions in connate water and thus reduces scaling in the downstream equipment during the production of viscous hydrocarbons.
