This paper describes the selection and installation of corrosion-resistant-alloy (CRA)-clad flowlines and solid Alloy 625 piping well-head tie-ins for hookup of wells in the Madden Deep Unit of Wyoming. The highly corrosive nature of the gas, coupled with the anticipated production of elemental sulfur and the close proximity to populated areas, dictated the use of these specialty materials. The special fabrication and installation requirements for CRA-clad flowlines, including some of the difficulties, are presented. The completion and production of high-pressure, high-temperature gas wells in the Madden Deep Unit of Wyoming has required the extensive use of CRA`s downhole because of the extremely corrosive conditions anticipated from the high H{sub 2}S and CO{sub 2} content of the gas.
