Abstract

Sudan is the largest country in Africa with an area of 2.5 million Km2 and common borders to eight<br>countries. Muglad Basin is a northwest-southeast trending rift Basin in Central Sudan. Blocks 1, 2 and<br>4 lie in the Central part of this Basin. Greater Nile Petroleum Operating Company operates these Blocks.<br>Muglad Basin is characterized by more than 15000 m of non marine clastic sediments; these clastic<br>sediments in the study area are likely to be sourced by northern and eastern paleo-highlands.<br>The combination of both continental (reservoir) and lacustrine (seal / source) rocks in conjunction with<br>the tectonics has created favorable juxtaposition of source, reservoir and seal.<br>The area of study has been relatively presented itself as a technical challenge to the operating<br>company. A team from Greater Nile Petroleum Operating Company (GNPOC) and Sudapet has<br>conducted geological modeling for the three main Upper and Lower Cretaceous reservoirs, namely the<br>Aradieba, Bentiu and Abu Gabra Formations.<br>The study comprised a 3D stratigraphic, facies and structural model building for the key horizons using<br>Petrel Software to capture reservoir variability.<br>Seismic attribute gave a clear expression of faulting and shows that all the productive wells were<br>located on a low frequency and low to high amplitude. The core data used in this study were<br>correlatable with the Petrophysical interpretation models. This oilfield has a multi-oil-water contact.<br>The petrophysical properties were modeled constrained by facies. The static model identified sand<br>bodies’ architecture that gave an increase in both oil originally in place (OOIP) and estimated ultimate<br>recovery (EUR).
