Abstract

The present work aims to recognize the geometry and build
modeling of the Oligo-Miocene unconventional igneous intrusions of
the fracture reservoir in Rudeis-Sidri field, Gulf of Suez, Egypt. These
reservoirs, much more difficult to predict, evaluate and to build
modeling than the conventional reservoirs. Seismic attribute is a
quantity extracted or derived from the seismic data that analyzed in
order to enhance information that might be subtler in a traditional
seismic image, leading to a better understanding and interpretation of
the data. Two attributes (Local Structural Dip), through detecting the
scattered dip from the seismic events, (Sweetness), through recognizing
the variations of reflectors, that have potential to predict possible
fracturing and absorption effects, to recognize the geometry to get
criteria to build the modeling process to differentiate between
sedimentary and basalt intrusions. As a result, the combination and
integration of the two types of seismic attributes, the available well log
data analysis as control points to establish building 3-D models, which
help to differentiate between the sedimentary and non-sedimentary
rocks, to delineate the geometry, distribution, and to follow the new oil
potentially at Rudeis-Sidri field
