DELINEATING THE GEOMETRY AND MODELING OF THE UNCONVENTIONAL IGNEOUS INTRUSIONS BY SEISMIC ATTRIBUTES; A CASE STUDY IN RUDEIS-SIDRI FIELD, GULF OF SUEZ, EGYPT

The present work aims to recognize the geometry and buildmodeling of the Oligo-Miocene unconventional igneous intrusions ofthe fracture reservoir in Rudeis-Sidri field, Gulf of Suez, Egypt. Thesereservoirs, much more difficult to predict, evaluate and to buildmodeling than the conventional reservoirs. Seismic attribute is aquantity extracted or derived from the seismic data that analyzed inorder to enhance information that might be subtler in a traditionalseismic image, leading to a better understanding and interpretation ofthe data. Two attributes (Local Structural Dip), through detecting thescattered dip from the seismic events, (Sweetness), through recognizingthe variations of reflectors, that have potential to predict possiblefracturing and absorption effects, to recognize the geometry to getcriteria to build the modeling process to differentiate betweensedimentary and basalt intrusions. As a result, the combination andintegration of the two types of seismic attributes, the available well logdata analysis as control points to establish building 3-D models, whichhelp to differentiate between the sedimentary and non-sedimentaryrocks, to delineate the geometry, distribution, and to follow the new oilpotentially at Rudeis-Sidri field
