Abstract
The JG field is located to the west of the North east Abu gharadig basin (NEAG). JG field main hydrocarbon production comes from Jurassic reservoir khatatba formation (LSA Mbr.). Data recovered from the JG wells have demonstrated that there is a very strong lateral variation in reservoir development and quality. The existing JG reservoir model does not provide a good basis for predicting reservoir behavior. The aim of this study is to reveal the reservoir facies and their environments of deposition in order to predict sand distribution and to determine the reservoir quality. The integrated approaches using the detailed results of well established sequence stratigraphic interpretation, wire line logs, core data and seismic interpretation, revealed the recognition of the incised valley and estuary systems as environment of deposition for the lower safa 2A3 Member. The incised valley system of JG is 35m thick, about 800 m wide and mappable over about 7 Km in length. The Valley exhibits a progressive eastward change in character and complicated reservoir architecture as a function of the interaction of marine and fluvial processes within the estuary
