New methodology for developing bituminous deposits
- Almetyevsk Oil Institute
Abstract
The aim of the method is to create a method of effective displacement of bitumen and thereby increasing the extraction rate of bitumen through direct impact on the bitumen and its host sandstone, as well as by reducing the size of the extraction cell to the optimal size, which virtually eliminates uncontrolled output of directed heat flow through tectonic fractures, bypassing the bitumen layer in the extraction element. The method includes drilling of injection, drainage and production wells, injection of coolant through the injection wells, dewatering of the bitumen layer with the drainage well and extraction of bitumen through the production well.
