Abstract
This thesis represents an integrated seismic and well logging study for Yomna field;
this area is located in the northern part of the East Bahariya concession which is located in the
northern part of the Western Desert. The aim of this study is to combine the different available
data to understand the subsurface system and the characters of Late Cretaceous reservoir (upper
Bahariya reservoir) at Yomna field. The current study started with the description of the geological
setting of the study area, including the stratigraphic sequence and dominating structures through a
review of the previous geological studies. Seismic interpretation was conducted on the available
seismic lines concerned with the study area to provide a detailed structural interpretation to
determine the structural geometry of upper Bahariya reservoir and Abu Roash “E” member for
detecting the best localities for drilling new development wells within the study area. The structure
contour maps confirm that the study area was affected by tectonic deformation system caused
regional uplift. Faults pattern plays an important role in the hydrocarbon potentialities of the study
area. Core analysis enables direct evaluation of reservoir properties and provides a basis for
collaborating other evaluation tools such as logs.
The well log analysis of upper Bahariya reservoirs includes data base editing, data correction,
determine lithology from logs using some types of cross plots and determine reservoir driving
mechanisms that control the behavior of fluids within reservoirs. Petrophysical data are illustrated
on Iso-parametric maps to indicate the lateral variation, good places for new productive wells, and
to perforate the bypassed promising intervals. from the results, it can be stated that the study area
may be considered containing hydrocarbon accumulation in different locations, and there is a good
opportunity to drill another development wells to enhancement the productivity from the area of
study. Seismic data and well log data have been done for proper optimization and development of
hydrocarbon potential at Yomna filed.
