| Assessing the probability of a gas accumulation in the Upper Cretaceous NB1 reservoir unit in the Nadym-Pur-Taz area | |
| This paper study the existing probability of a gas accumulations in the Upper Cretaceous NB1 reservoir unit in the Nadym-Pur-Taz area of Western Siberia. The objective assessment of the probability of gas accumulation existing in the NB1 reservoir unit was addressed using a methodological approach based on stochastic modeling of reservoir parameters using their critical values. The key factors controlling the existence of gas accumulation in the NB1 reservoir unit are analyzed. It is concluded that the primary critical factor is the presence of an effective reservoir with a pore structure that does not impede gas accumulation and filtration. Keywords: gas accumulation, NB1 reservoir unit, Upper Cretaceous, stochastic modeling of reservoir parameters, reservoir probability, Nadym-Pur-Taz area, Western Siberia. |
