... the ponded water depth and the subsurface temperature profile. Subsequently, a procedure was developed to design adfreeze (standard) VSMs, Helix VSMs, and Thermo Helix VSMs in areas of ponded fresh water. This paper presents the temperature profile of the permafrost beneath ponded water and addresses...

... Abstract The degree of corrosion of weldments on offshore structures and vessels depends upon the metallurgical characteristics of steels and welding consumables, the welding procedures, and the environmental severity. A new procedure has been developed for evaluating the preferential corrosion...

This paper describes the use and field performance of the plug in the off-bottom cementing procedure, and reports pre-set fluid properties, chemical and physical properties, and mixing and spotting procedures. Information is also presented on how the plug has been used to combat difficult lost...
