نظرا للمعالجة الواسعة و السريعة التي يقدمها برنامج petrel فقد اعتمدنا عليه في بناء نموذج جيولوجي ثلاثي الأبعاد للخصائص البتروفيزيائية {للمسامية، النفوذية، مقدار التشبع بالهيدروكربون { Bo ،N/G ،GRV(Gross Rock Volume) ، الإضافة إلى تحديد مستويات التقاء نفط – ماء للمنطقة المدروسة ( حقل الصبان تشكيلتي الرطبة و الملوسا ) و ذلك من أجل حساب الاحتياطي النفطي بشكل محدد و مقارنته مع الدراسات السابقة من أجل تعميق الفهم النفطي للمنطقة و تحديد فرص حفر مأمولة.
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 Rock 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.
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 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
appropri
ate 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.
In this study, we study the applications of DCA technology to
calculate the specifications of the reservoir by using the equation of
the material balance in the modeling and simulation programs in
order to estimate Geological reserve. This techniq
ue is based on the
analysis of the decline in production, which is the analysis of the
previous data of the decline in production performance, which is
expressed in the graphs that link the rate of production and time, or
the rate of production and cumulative productivity. For each of the
wells and reservoirs, and we will take in this research these curves
from 1975 to 2005. We will specialize in research one of the fields of
the Euphrates (Thayyem field– Alrutbah formation) hoping that this
modest study will achieve the desired goal.
