The Detection Of Gas Bearing Channels From Seismic Interpretation And Reservoir Modeling In Mediterranean Sea.

During the last ten years many of gas fields have been discovered in Egypt, the majority of the gas reservoirs discovered within these fields were categorized dry gas in Pliocene age and the others are Miocene gas reservoirs. In the presentation we will introduce the gas fields discovered till now and how to control the success ratio in drilling exploration wells from seismic interpretation. Also we will make a high lights on how we build the geological model directly from seismic output process and the methods which are used to detect and prove the extension of gas channels. After that we present how to build the engineering model from geological model, fluid properties, rock properties and all the petrophysical data. As a result of this we calculated the original gas in place (OGIP), then we will show the sensitivities which are used to detect the recovery factor (R.F) which directly effects in the estimation of gas reserves. Finally, this paper illustrates the impact of 3-D seismic on the reservoir modeling to confirm the Following:1-Original oil in place 2-Recovery Factor 3-Gas reserves 4- Aquifer strengthThe presentation will throw the light on the gas discoveries so far and how to control the success ratio in the exploratory wells and the drilling strategy. Our conclusions and recommendation, based on the results of this paper, will help to improve the ultimate reserves and encourage the foreign companies to explore gas fields in Mediterranean sea area which is good prospects in gas fields discoveries as a results of this Egypt gas reserves increases.
