Economical and technical Study of replace the field solvent (NaOH) with improved solvent to prevent sulfur deposition in gas wells

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 wells 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.

Using the chemical method to removal the sulfur deposition in the tubes of sour gas production in Jbissah fields

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.
