Analysis of efficiency of steam-gravity recovery technology for development of heavy oil reserves

Authors: R.S. Khisamov (Tatneft OAO, RF, Almetyevsk)

Key words: bituminous oil deposits, Ashalchinskoye field, horizontal wells, temperature, thermal recovery method, oil recovery factor.

In 2006, Tatneft OAO initiated application of the steam-assisted gravity drainage technology to develop the reserves of the Ashalchinskoye shallow heavy oil field. The paper presents analysis of pilot production. Field performance testifies to success of the heavy oil development project and practical feasibility of 70% of ultimate oil recovery.
