Abstract

The southern part of the Gulf of Suez contains all elements of
entrapment (source rock, reservoir and cap rock) to be one the most
prolific hydrocarbon generation zone especially in Kareem, Nukhul
and Pre-Miocene Formations.
The southern part of Gulf of Suez is one of the important
areas for evaluation and study, to explore the hydrocarbon migration
locations.
We have focused the evaluation and study in South Ramadan
field as a case study in the south part of the Gulf of Suez due to the
following reasons:
a) South Ramadan Concession field is located offshore in the
Southern part of the Gulf of Suez-Egypt.
b) It is 15 km. to the East-Northeast of ”Ras Gharib City” and
about 15 km. to the northeast of Ras Shukheir Field Base.
c) In general it is located in the most prolific part of the Gulf of
Suez. It is surrounded from the north by Ramadan, from the
east by El-Morgan, from the south by LL87 and from the west
by ESMA/LL87 Development fields.
In the present study for the South Ramadan field the surface
beneath salt cover, this is lead to several problems due to masking
the subsurface layers, conjugated zones cause several deviations in
fault pattern, dip direction and amount in addition the field suffer
from old and poor 2D seismic data.
The traditional interpretation for the old 2D seismic data
creates untrustworthy maps as it cannot reveal the picture beneath the
salt section additionally not accurate due to multiples and ringing
affected on the seismic data.
iii
The purpose of the study is to solve these problems by using
new seismic data in the depth domain to construct new accurate
structural maps tight with regional geological data,
By interpreting magnetic data that cover the area of study, to
make a regional evaluation for the main faults that influence on the
structure setting of the field.
Moreover revised from stratigraphy point of view, and
identify the hydrocarbon potentialities area to integrate the data in
3D Static model represent the subsurface layers from structure and
the reservoir characterization point of views.
So; we use new vintage of 3D seismic data migrated in the
depth domain to introduce new interpretation and create new seismic
attributes, as the seismic imaging in depth domain is the most
powerful tool in delineating the surface zones beneath the salt bulge
cover the field area.
Using all available well data and seismic data, besides that
utilized the advantage of software facilities of (Geological and
Geophysical studies with integration of advanced software for 3D
static model), and previous studies contribute to understand some
points.
Using charisma® and Petrel® software gave a great support to
achieve the study and minimize a lot of the previous problems, in
addition to new modern technology for analysis of every piece of
data has been applied to make use of the integration between the
seismic data and well data.
After solving these problems, accurate maps for stratigraphic,
structural and hydrocarbon potentialities of South Ramadan oil field
have been established honoring the seismic and well data tight with
iv
regional geology. These accurate results have been inputted in
building 3D static model which represents the most mature phase, to
correlate and confirm the results in order to detect the best area to be
drilled.
The final results show excellent progress in the area
development plan from technical and economic points of view, as it
shows new attribute technique to enhance the subsurface image and
help to identify structure features and depositional environments,
Seismic interpretation and mapping indicate that the structure of
South Ramadan Field represent a typical rift structural setting within
the transfer zone between two major rift segments with different
regional dip regimes. This transfer is located between the southern
Gulf of Suez structural province with regional southwest dip regime
and the central structural province with regional northeast dip
regime, which are consequently have opposite directions of fault
throws northeast and southwest directions respectively. It classified
as conjugate zone and characterized by gentler structural dip of
Miocene and Pre-Miocene Formations as a result of the competition
between the two different regional dip regimes.
3D Static model is an integrated procedures for 3 dimensional
static modeling and visualization of the reservoir starting from input
of seismic and well logging data until output of an upscale geological
model for export to reservoir simulator, these procedure involved
two main stages which are structure framework and petrophysical
modeling.
Well proposals had been introduced to detect and identify the
valuable blocks to explore and developed to add significant potential
to the field reserve.
