Critical geological risks for the plays

Authors: E.A. Lyzhin, E.A. Bulgakova, N.V. Nassonova, Lazar E.L. (TNNC LLC, RF, Tyumen)

Key words: risk, assessment, play, trap, seal, saturation, reservoir.

The article represents the approach for risk evaluation. This approach was tested in Uvat Exploration Project, which is situated in the southern part of Tyumen State. The main factors of risk include: trap, saturation, reservoir, seal. The using of the approach allowed to improve the success of exploration and give the opportunity to control the risks.
