DEVELOPMENT OF ULTRA-HIGH VISCOSITY OILS BY THE SAGD METHOD: PROBLEMS AND PROSPECTS

Annotation. Recently, much attention has been paid to the accelerated commissioning of unconventional sources of hydrocarbon raw materials. Russia has large reserves of heavy oils and natural bitumen, which are one of the most important promising sources of hydrocarbons and are classified for taxation as extra-viscous oils. These reserves are concentrated at a relatively shallow depth, but they are difficult to recover. The article discusses the use of Steam Assisted Gravity Drainage (SAGD) for the extraction of ultra-viscous oils, describes the principle of the SAGD method based on steam injection into horizontal wells to reduce oil viscosity and gravity drainage. The effectiveness of SAGD for the development of deposits inaccessible to traditional methods is emphasized.

Keywords: drainage, gravity, steam, ultra-viscous oils, horizontal wells, bitumen-saturated oils.
