... the effect of both structure and facies heterogeneities on fluid flow. A model of an unfaulted system was presented to make the case. In the study area there is inter-fingering between oil and gas across different formations; most oils are trapped in the deeper formation, oil and gas inter-fingering occurs...

... includes the following stages: - field geological study, facies analysis (integration of well geophysical complexes, cores); - deduction and correlation of sequence boundaries; - construction of discrete log, which corresponds to specific sequences distribution; - conducting seismic...

... available subsurface data and used inverted seismic attributes calibrated to the available logs to constrain the property modelling. Then various deterministic and stochastic approaches were used for facies modeling and estimation of gas-in-place volume. Integrating all the available data provides insights...
