تم تحديد مختلف الفوالق التي ضربت منطقة التنك من خلال دراسة المقاطع السيزمية في عدة اتجاهات و بتباعدات محددة، و تكثيف تلك التباعدات لزيادة دقة وضوحها و باستخدام أنسب أنواع خرائط الخصائص السيزمية للمسح ثلاثي الأبعاد (خريطة تقوية الحد - خريطة السمت و الميل - خريطة السمت - خريطة الميل - خريطة الجذر التربيعي للمطال السيزمي - خريطة الاستقطابية - خريطة التردد) للضبط الدقيق لتلك الفوالق و الشقوق في المنطقة المدروسة، و خصوصاً لتشكيلة الرطبة. و كان لتطبيق الخرائط السابقة على سطحها السيزمي مؤشرات مفيدة و داعمة من أجل تحديد مكانها الأمثل. و تمت مقارنة هذه الخرائط مع بعضها بعد تصديرها إلى برنامج Petrel إلى جانب الخارطة الزمنية لمنطقة الدراسة. و بالنتيجة تم الوصول إلى مواقع الحدود الفالقية بأكبر دقة ممكنة بالاستفادة من البرامج الحاسوبية: (Geoframe - Petrel –Word).
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 types 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).

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 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.
The research aims to contribute to the knowledge of scholars of Palestine in the science of interpretation, particularly one of the fundamental reform of the science of interpretation of this flag is the author of Muhammad Izzat Darwaza modern interp
retation, The first topic devoted to the for definition Darwaza and of his time for the detection of the most prominent reasons that have contributed to the formation of ideas and opinions, and made the topic the second platform for the reform of the modern interpretation of interpretation for the detection of the position of the previous interpretations of Darwazeh and diagnosis of the gaps where there were repeated, and a plan for the best understanding and interpretation of the Koran in order to overcome these gaps, and then made the topic of the third The concept of destination as the basis for the reform of destination and the focus of reform of science in the interpretation of the modern interpretation.
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.
