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.
