...) on a six-roll cold straightening process, it was found that seamless oil country tubular goods (OCTG) pipe has a unique residual stresses pattern due to its manufacturing process. An X-Ray diffraction through wall residual stress measurement shows that even with hot straightening, there is still...

... at a temperature of 150°C (302°F). Martensitic Stainless Steel UNS S42028 SCC tubulars clear brines INTRODUCTION The oil industry is pushing the drilling-technology frontier forward with enthusiasm, despite the high costs of drilling deep wells. ¹ Numerous operating companies are pursuing new...

... The candidate waters available for secondary recovery of oil in West Kuwait oil fields are all high in salt. Total dissolved solids (TDS) of an aquifer water is 239,000 ppm (chloride, 146,000 ppm). Effluent water varies, but TDS can reach 241,000 ppm (chloride, 151,000 ppm). Candidate materials for tubulars...

...Abstract Tubulars used in underbalanced sour drilling can be subjected to more severe environmental conditions than encountered in traditional overbalanced drilling. This paper describes testing conducted with the double cantilever beam technique in simulated environments, discusses performance...
