ABSTRACT:
One string of corrosion resistant tubing and a casing string which has a corrosion resistant bottom section can be connected between a wellhead and a deep, hot reservoir so that a corrosive reservoir fluid can be produced while keeping it isolated from wellbore or wellhead tubulars of conventional low alloy steel thus preventing corrosion without maintaining a downhole injection of corrosion inhibitor.
