Digital outcrop models reduce uncertainty and improve reservoir characterization

摘要

Carbonate formations in the Middle East of Permian-Triassic age, often collectively called the Khuff Formation, are among the region's most prolific reservoirs. The best-known example is the world's largest gas field, the South Pars and North Dome gas condensate field in the Persian Gulf, which is estimated to have over 1,300 Tcf of gas initially in place. On a field scale, Khuff-type carbonate strata are strongly layered and can be correlated over distances more than 10 km. Nevertheless, within the layers, significant reservoir property partitioning is present.
