Using multiattribute analysis to predicting effective porosity of Yamaha formation in Nasiriya oilfield ٍSouthern Iraq

الملخص EN

Emerge application was used in hampsson-russell programs and that uses a combination of multiple 3d or 2d seismic attributes to predict some reservoir parameter of interest.

in this research used the seismic inversion technique was performed on post-stack three dimensions (3d) seismic data in Nasiriya oilfield with five wells and then used this results in emerge analysis (training and application) were used to estimate reservoir properties (effective porosity) with multiattribute analysis derive relations between them at well locations.

the horizon time slice of reservoir units of (yb1, yb3 and yc) of Yamaha formation was made for property (effective porosity) to confirm match results and enhancement trends within these units.

because of the good prospects of the oil in the rocks of cretaceous generally and Yamaha formation specially in the Nasiriya oilfield and in view of the economic importance of Yamaha formation, which is considered as important formation that contains hydrocarbon accumulation, and one of the most important and oil production reservoirs in southern Iraq.
