CONTROLLED LOCATION OF THE PRECIPITATION OF SCALE IN RESERVOIRS

摘要

A process for enhanced hydrocarbon recovery from a reservoir by actively forming scale within the reservoir. Predetermined locations for the deposition of the scale are calculated and a mix of scale inhibitor (s) and injection fluid are introduced through injection wells into the reservoir. As the scale precipitates through the reservoir, fluids are diverted to preferentially sweep locations thereby recovering increased hydrocarbons at the production wells.
