The efficiency of exploratory drilling largely determines the economic prospects for the development of the territory. When conducting prospecting and exploration for oil and gas, companies strive to reduce the negative results (30–40 %), and for this purpose they perform an assessment of geological uncertainty and various methods of accounting for geological risks. According to modern concepts, geological risk is understood as the probability of a negative result when searching for a deposit at the research site. The inverse value of geological risk is the success rate of exploration.
Materials and methods
The work is based on the results of geophysical, lithological, petrophysical studies, as well as the results of basin modeling.
The assessment of geological risks was carried out for 2 400 promising objects.
