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).
In area of Elward east located in Euphrates Graben, 2D and 3D
Seismic data were used to reveal subsurface geological structures,
especially Reservoir Rutbah Formation dated as Lower Cretaceous
and to explore hydrocarbon traps of this Formation. And to
discover new drillable locations by integrating geological and
seismic data and using seismic attribute techniques such as Dip
and coherency.
Study of faults at Lattakia region shows normal, reversed and
strike-slip faults. Main fault directions and their geologic age
estimation were determined. The normal faults have NE-SW
main direction from Middle Miocene and E-W secondary
direction from Paleogene.
Joints study in Skhaba region shows the existence two joint directions, principal dominant
NW-SE Joints from extension origin upper Cretaceous age, unrelated and older than faults
in studied area statistically, the presence of Calcareous filling in
the joints that is supported
the extension origin in the first phase. Secondary NE-SW joints from Miocen-Pliocen in
age, and from extension origin ,related to the formation of faults, most of them contain thin
iron crust in secondary phase.
