تم في هذا البحث اقتراح مذيب كيميائي لإزالة ترسبات الكبريت ضمن مواسير إنتاج الآبار الغازية التي تعاني من هذه المشكلة بكثرة. حيث تم إجراء دراسة مرجعية حول خصائص الكبريت وأشكال تواجده في الطبيعة و شرح المخطط الطوري للكبريت والشروط الواجب توافرها لترسب الكبريت الحر ضمن مواسير الإنتاج و توضيح آلية الترسيب ومخطط مبسط لعملية تشكل نوى جزيئات الكبريت من البخار فوق المشبع. كما تم الاعتماد على المعطيات الحقلية للبئرين المدروسين /جبسة-445، جبسة-442/ (المأخوذة من التقارير التشغيلية اليومية وذاتية البئر) في إجراء تجارب مخبرية بهدف المقارنة بين المذيب المستخدم حقلياً (NaOH) والمذيب المقترح (المذيب الكيميائي المنشط بالأمينات الدهنية) في هذه الدراسة لإذابة الكبريت المترسب ضمن مواسير الإنتاج وبالنتيجة تم رسم المنحنيات البيانية الناتجة عن عملية المقارنة والتوصية باستخدام المذيب المقترح في عمليات معالجة آبار الغاز الحامضي في حقول الجبسة التي تعاني من هذه المشكلة كونه المذيب الأكثر فعالية واقتصادية.
In this paper, a proposal a chemical solvent to remove sulfur deposits within the tubes production of the wells that most suffer from this problem are done. Where the study was conducted on the referenced study about the characteristics and forms of sulfur in the nature, and explain the Scheme phasic of sulfur and required conditions for the deposition of elemental sulfur within the tubes production. And has been clarified the mechanism of deposition and the outline of a simplified process for the nuclei of molecules from supersaturation sulfur vapor. Has also been depend on the field data of the studied wells /Jbissah-223, Jbissah-220/ (taken from the daily operational reports and Historical Biography of the wells), to conducting laboratory experiments in order to compare the between used solvent at field (NaOH) and proposed solvent (tallow amine activated diethyl disulfides) in this study in terms of the melt the deposited sulfur within the tubes production. and as a result, the curves resulting from the comparison process was drawn and recommending the use of the proposed solvent in treatment the acid gas wells in Jbissah fields that suffer from this problem where this solvent is the most effective and economical.

In this paper, detail technical and economic feasibility study are
implemented to use the improved solvent instead of the used
solvent in Syrian field (Sodium hydroxide, NaOH) until this time, to
prevent and remove the sulfur deposits in the gas w
ells that most
suffer from this problem.
Has also been confirmed on the technical best method for
suggested solvent injection and depend on the field data of the
studied wells /Jbissah-223, Jbissah-220/ to carrying out the required
economical calculations, and the sensitivity analyzing for changes
of economical with changes of dollar exchange rate and gas
production rate from studied wells are performed, and then the
curves of economic Feasibility study resulting from the
comparison process was drawing. And recommending the use of the
improved solvent where this solvent is the most economic solvent.
The use of sonic method to detect reservoirs with secondary porosity
(fissures and cavities) was due to the high effect of this porosity on the elastic
waves.
The generalization of the experimental results helped to construct a
diagram to be used
in detecting reservoirs with secondary porosity in the wells.
A joint analysis of the data of the sonic method and other well logging
methods, such as boreborehole diameter log, natural radioactivity log, natural
log and micro and deep resistivity log...etc, was achieved.
The wave spectrum was analysed for a relatively long period so that it
included Lambi waves.
The detection of these reservoirs was achieved by using the correlation
between all available results, which led to the determination of the presence of
the secondary porosity and the suggestion of a new calculation method.
In addition to the secondary porosity some other factors which affect the
sonic measurements were mentioned.

This paper includes was clarified the objectives of this study and
the problems caused by gas hydrate formation problem in the
studied gas transportation lines, and submit of the studied fields,
contains all the required data in this research.
The Objectives of this research are to study the Oil Formation
Covered with Water or Gas, Formation of Water or Gas Coning and
Mathematics Control Mechanisms of it, then to know the Water
Coning Isolating Types in the Syrian Fields (as ALRoumailan
and
ALGbisseh).
The ancient people had used and kept a lot of tools and most important of
all were clay cooking pots and dishes, etc.., and they left them as remains to tell
about the way they were living and feeding . So, it was quite important to carry
out some
analysis on the organic residue of archaeological clay sherds from
cooking pots or dishes from the area of Homs from the era of the Roman and
Islam. A Special attention was focused on the analysis of lipids, which have the
properties of resisting the effect of the environment after it is absorbed in the
clay matrix. Lipids can be extracted with suitable solvents, either total
extraction, or after the treatment of the undisolved portion of the clay with
alkaline. Analysis using gas chromatography and gas chromatography - mass
spectrometery, revealed the existence of mono and di carboxylic acids,
saturated and unsaturated fatty acids, alkanes, and mono, di, and tri glycerides.
The measurement of the ratio C١٦/C١٨ gave the indication to the use of animal
fats in these pots.
