... ABSTRACT This paper presents a categorized grouping, by function, of metal seals used in oil field drilling and production equipment. A set of inter-related design principles and a design methodology are presented to aid in the design process. INTRODUCTION The use of metal seals in oil...

... capability, positive casing hanger lock-down, and a high performance metal sealing system. The advantages of this system are particularly applicable to offshore platform installations in terms of both economics and safety. INTRODUCTION An operating company is developing offshore fields with deep, hot...

... ABSTRACT Metallic seal systems are relatively new to downhole completion equipment. Their incorporation into downhole products represents a trend toward higher technology in extreme service applications. The foundations for metal seal design have long been established in other industries...

... applications are resilient seals and metal to metal seals. A third seal material category can be defined which is best described as seals which are not reliant upon the material's elastic properties to seal. These are typically used for their fire resistance and typically have not been used in subsea equipment...
