Abstract

Shukheir Bay Field is part of the Shukheir Marine Concession located in
the northern part of the Gulf of Suez. It occupies a total area of 22.5
Km2
. The main reservoir in the Shukheir Bay field is the Rudeis sands of
Miocene age, however this study focuses on the lower clastic unit in the
formation that usually referred to as Lower Rudeis Sandstone. The
petrophysical evaluation of this sand zone was conducted using a
complete set of open- hole well-logs in the available wells. The
lithologic composition is identified as sand intercalated with shale.
Seismic interpretation was deduced to determine the structural geometry
for detecting the best localities for drilling developmental wells in the
study area. The top and bottom surfaces of Lower Rudeis Sandstone
were identified and traced in the whole area of Shukheir Bay Field.
Depth structural contour map was constructed and the major faults were
detected. 3D static model, using seismic and well log data has been done
for proper optimization and development of hydrocarbon potential in
Shukheir Bay Field. Seismic data were used to generate the input
interpreted horizon grids and fault modeling. Petrophysical parameters
(effective porosity, shale volume and hydrocarbon saturation) were
distributed and mapped within the constructed 3D grid, using
deterministic Kriging algorithms, while facies were distributed and
mapped by deterministic facies modeling method. By integrating the
results of all available data sets, this study recommends to drill
development wells in the central part of the study area.
