Modeling the transition zone of the Cenomanian gas reservoir

Low-pressure gas production is one of the most important tasks in gas field development. To estimate the reserves of previously uninvolved reservoirs with low reservoir properties, it is necessary to analyze available geological and geophysical information for the subsequent creation of a three-dimensional geological model. Based on this model, a filtration model will be built, which allow calculating the flow rates of both actually drilled and designed wells for the entire development period. The model is built on the basis of small amount of information content, but the modeling results sufficiently reflect the presence of a zone of poorly saturated part of the Cenomanian gas reservoir, and structural and petrophysical features of the reservoir in the territory. As a result of the conducted research, the low pressure gas reserves at the Yamburgskoye field were calculated. The calculations, which are given in the article, are correct and don't contradict the Regulations on the creation of permanent geological and technological models of oil and gas and oil fields (RD 153-39.0-047-00).
