Static reservoir modeling of El Wastani formation, for justifying development plans, using 2D seismic and well log data in Scarab field, offshore Nile Delta, Egypt

Abstract

Static reservoir modeling adequately and precisely defines the reservoir framework (geometry) and architecture (property). So as to substantially reduce the expected risk while defining the hydrocarbon-bearing reservoir boundaries, static geocellular model was constructed, in this study, to define lithology and fluid stochastic distribution, and volume of hydrocarbons as well, within the Late Pliocene hydrocarbon-bearing El Wastani Formation, (sandstone channel-1 and channel-2), in Scarab Field (offshore Nile Delta, Egypt). Twenty 2D seismic lines and well log data, of four wells, were used in this study. Stratigraphic, structural, facies, and petrophysical models were applied not only to estimate the volume of hydrocarbons within the reservoir but also to identify the best location for proposing new development wells that are of crucial value for oil industry development. In accordance with the constructed reservoir geocellular model, we found that the northwestern part of Scarab field is the best location for running further oilfield development plans.
