Keywords: cash risk assessments, cost-effectiveness of exploration, near-fault and tectonically shielded hydrocarbon deposits

Annotation:

As it is known, in almost all oil- and gas-bearing provinces of the world, including Russia, a significant number of the so-called tectonically shielded by the Earth's crust faults hydrocarbon deposits have been discovered. However, the success of prospecting for new deposits near the faults is still low. Therefore, in the current conditions of sharply limited investments in geological exploration, there is an urgent need to clarify the possibilities of forecasting highly efficient, highly productive near-fault deposits using modern geophysical methods. The article shows the possibility of numerical monetary evaluation of geological exploration risk, based on the seals identification and mapping above the reservoirs of predicted near-fault deposits. Fundamental differences between tectonically sealed and near-fault hydrocarbon deposits are shown.
