The Upper Crétacé rocks of Krashok formation, Massive formation and Shiranish
formation, are very important for petrol and gas reserve, where it is the importance petrol
reserves in Syria. 25 samples of these two formations werestudied.The Massive
formation
had a good Petrological character as reserves rocks ,where it contain calc rocks, which
have good reserving properties, and it cover the hole area , and it contain a petrol. Where
the Shiranish formation is almost homogenies, and contain calc-marl-clay rocks with
foraminifera, and it divide into three zones, depending on it is petro physical properties, the
upper zone is the most absorb of petrol, by comparison whit others zones, which show
there are many indicators reserve characteristicin these formation.
The geophysical surveys on the Syrian oil fields had begun since (1933);it
continued by the soviet groups (1952-1962) and were completed by the Syrian
national groups. The Derro oil field had a good lot from these studies, because
it was surveyed
and studied by the all known geophysical methods (gravity,
geoelectrics, siesmics, well logging).
This was possiple due to the fact that oil bearing formation in the above
mentioned field lays in very shallow depths, in comparison with the known oil
fields, the geoelectrical method was applied with good results and extreme low
cost.
Obtaind results, by studing ١٢٥ samples from ١٠ deep wells covering the
different Triassic formations in NE-Syria,show the existence of various
inclusion types. Aqueous, carbon and hydrocarbon-bearing. Aqueous inclusions
vary widely in their general and physico–chemical features, form, melting and
homogenization temperature, and density of the enclosed fluid.
Shiranish formation in Sazaba Oil fields region had been divided by
Petrology study and well Logs measurements to three major members (lower –
middle – upper). Then these members have been divided to lithostratigraphic
units and subunits. This stu
dy showed that the lower member is formed of
clayey - limestone rocks rich in planktonic foraminifera and glaconitic sand.
The middle member consists of organic limestone facies, dolomitic-limestone,
sometimes clayey - limestone rocks with crystals of pyrite and glaconitic sand.
Organic- limestone rocks and detrital limestone are predominant in the upper
member interbeded by dolomitic-limestone and rare clayey – limestone. This
facies contains pelagic and planktonic foraminifera.
The role of diagenes phenomenon is evident on Shiranish’s facies through:
dolomitization according to burial and miksing processes. It is also clear
through chemical compaction, mechanical compaction, cemenation,
micretisation and silisification.
This research define and study geomorphological properties of the Karstic Polje,
located in the southern parts of the coastal area “Beerat Aljerd and Ein alshams rgeons”
For this issue, we have used “ G I S” Technology to clarify properties and pla
ce of
this Polje through construction few of informatics slides that contain different types of
data, showing Karstic Polje limits, dimensions, topography of the region, and situated
Karstic characteristics Blind valleys, sink holes, solution doline, hums. Following, we have
studied the Paleogeogeaphic development of the study area, in addition to the forming
conditions, and Geomorphological periods related with this region.
Finally, This study showed the great hydrology importance, resulted from presence
of this Karstic Polje in the mentioned region, through infiltration of large quantities of rain
water by precipitation with annual average up to 1475 m m. This water moves often
through water bearing formations toward the west, where flow out of the Polje and
contribute in consisting of water storage for the coastal area.
