Those deep, hot, sour, high pressure wells
Based on Shell Oil Co.'s Mississippi experience, development and availability of the following supplies and technology will facilitate expanded, economical development of deep, sour-gas wells in the U.S. and elsewhere: additional suppliers of thick-wall sulfide-stress-cracking-resistant casing and SSC-resistant tubing; higher strength SSC-resistant casing and tubing, high-strength corrosion-resistant tubing; inhibitors and carrier oils that are less soluble in the produced fluids and provide corrosion protection at flowing bottom-hole conditions; wireline equipment that can withstand the sour gas, temperatures, pressures, and depths of future super-deep wells; high-weight completion and workover fluids with better solids-suspension characteristics, low solubility in produced fluids, and stability in acid-gas environments; phase-behavior studies at high-pressure and temperature of simulated reservoir fluids containing free sulfur; and more extensive training for all concerned as to the hazards effects of hydrogen sulfide on materials and life.
