إن الدراسة المخزونية الصحيحة للمكمن تقودنا إلى وضع برامج حفر مناسبة للطبقات المنتجة، كما تجعلنا نقوم بعمليات استثمار ناجحة لتحقيق أفضل عامل مردود، و بزمن مناسب، و بأقل التكاليف، و تساعدنا على تجنب أو حل العديد من المشاكل المرافقة لعمليات الإنتاج، و أهمها مشكلة الإماهة. يعرض هذا البحث تحليل معطيات لدراسة جيولوجية و خزنية لحقل الجيدو، و هو أحد حقول شركة الفرات، و يقع ضمن منطقة منخفض الفرات في محافظة دير الزور شرق سورية، حيث يقدر الإحتياطي في هذا الحقل بحوالي 83 مليون برميل، و كان الهدف من الدراسة معرفة مواصفات و سلوكية الخزان و السوائل بداخله، و امكانية وجود اتصال هيدروديناميكي بين كتله، حيث تؤخذ هذه المعلومات بعين الإعتبار عند حساب الإحتياطي و تعيين المؤشرات التكنولوجية للإستثمار الأمثل.
The correct study of the reservoir leads us to develop drilling programs suitable for producing stratum. In addition, this makes us do successful operations to achieve the best recover factor ,within the convenient time and at the lowest appropriate cost. This study will help us to avoid or solve many of the problems associated with the production processes and the most important problem of rehydration .In this research I did a geological and reservoir study of the Jido Field which is one of the fields of the Euphrates Company and it is located within the area of graben Euphrates in Deir Azure to the east of Syria, where recoverable reserves which are estimated in this field is about 83 million barrels. The objective of the study was to know the specifications and behavior of the reservoir and fluid inside and the possibility of a Hydrodynamic connection between blocks ,where this information is taken into account when calculating recoverable reserves and the assign of technological indicators for investment.

Al Rutba Formation , bellowing to the upper Cretaceous, is one the
main formation of the stratigraphical coumn of Euphrate Depression.
It is importance becomes from that it can statute the principle
petroleum reservoir in high member of the depres
sion fields.
Producing oil and the natural gas.
The importance of this group is to be the main reservoir of oil in
various fields of low oil producing natural gas. The present study is
based on subsurface geological data, presented by cores, well logs and
chemical results of the analyses laboratory.
The various faults that hit the Tanak area were identified by
studying the seismic sections in several directions and with specific
exclusions, and intensifying those exclusions to increase their
accuracy of clarity by using the most appropriate t
ypes of seismic
attribute maps for the 3D survey (Edge Enhancement map -
Artificial Illumination map - Azimuth map - Dip map - Seismic
Amplitude map - Polarity map - Frequency map) for accurate check
of these faults and cracks in the studied area especially for Al-
Rutbah formation. We found helpful and supportive indicators in
order to determine its optimal location by applying previous
seismic maps on its seismic surface. These maps were compared
with each other after being exported to the Petrel program besides
the time map of the study area. As a result, the fault boundaries
were determined as accurately as possible by using the programs:
(Geoframe - Petrel -Word).
The inclined shear restoration technique was used in this research as the primary
method to remove the effects of fault displacements. These displacements were resulted
from the impact of the NE-SW trending extensional forces. The inclined shear re
storation
technique was applied to the NE-SW trending seismic section (Inline A2157) along the
Elward Area, using 2D move software.
The vertical shear restoration technique was used as a complementary method to
remove the effects of folding associated with faulting, especially to formations under the
Base Upper Cretaceous Unconformity (BKU).
The inclined shear and the vertical shear restoration techniques contrib uted to build
many geological sections according to depth seismic section (Inline A 2157). These
sections showed the Tectonic setting of the study area from Upper Ordovician till current
time.
Due to the extensive and rapid processing of the Petrel program, we
have relied on it to construct a three-dimensional geological model of
the petrophysical properties of porosity, permeability, amount of
saturation of hydrocarbons, GRV (Gross Roc
k Volume), N/G, Bo, In
addition to determining the oil – water contact levels For the studied
area (Sabban field, - Ruttba and Malussa Formations) in order to
calculate the oil reserve in a specific way and compare it with
previous studies in order to deepen the oil understanding of the region
and identify potential drilling opportunities.
Due to the wide and rapid processing provided by the petrel program,
we have relied on the construction of a three-dimensional statistical
model of the studied area (Sabban Field - Ruttba and Malussa
Formations) using data for well-studied wells (
geochemistry,
geophysical measurements and interpreted seismic data) To complete
the reservoir study in a subsequent study.
