Ultra-deep oil: comparison of oil and gas bearing basins and prospects for exploration for ultra-deep deposits (Sichuan, Tarim, Permian, Canning and Precaspian basins)

Abstract

The article reviews information on oil and gas bearing basins, where considerable experience has been accumulated in the geological study and development of the so-called ultra-deep oil and gas deposits (depths over 6000 m), on the geological structure, discoveries within the considered oil and gas basins, data on wells drilled to great depths, including test results, reservoir fluids reserves and properties.
