Simulation Study of Well Deliverability Reduction Due to Sulphur Deposition in Naturally Fractured Carbonate Reservoir

The sour gas reservoir of interest is the fractured oolitic dolomite formation, containing dry gas with high H2S and CO2. Elemental sulphur (S8) dissolved in sour gas may precipitate in both the near-wellbore reservoir region, tubing and surface facilities, along with the pressure and temperature decreasing in the flow process. The precipitate may form gas flow restrictions.
