<p>K 9452 A sour natural gas is produced via a well system comprising a vertical well section and a horizontal drainhole section extending through the reservoir formation. Formation plugging due to in-situ precipitation of sulphur during production operations is avoided by adequately sizing the horizontal drainhole section in the reservoir, thereby establishing near-wellbore pressures in the reservoir above the sulphur saturation pressure, without sacrificing production rates.
