Analysis of promising technologies in the development of heavy oil deposits based on russian and international patents

Identify the most promising technologies in the development of heavy oil deposits by analysis of the patent situation in Russia and abroad. For definition of the patent situation is put statistical analysis of patent documentation relating to the subject of patent research: "Methods of production of hard-and non-conventional hydrocarbons (kerogen, bitumen, heavy and high viscosity oil)". Statistical analysis of the patent literature is an additional source of information on technical and technological conjuncture in the industry.
Materials and methods
Statistical studies based on russian and international patents.
Results
Identify the most promising methods in the development of high-viscosity oil field.
Сonclusions
At present, the preference in the development of technologies in the field of high-viscosity oil, is given to the use of horizontal wells with termal methods, both in theory and in practice. Also have a good prospect relatively new technology in the production of highly viscous oil, which in the opinion of the authors have significant advantages in the technological and economic aspects over conventional thermal methods.
