BG have invested a lot of time & effort on the issue of Green Dope.
BG performed a field trial of ELS325AG on L80 VAM top connections
for 13.3/8" & 9.5/8" casings a year ago. The results were good, with
no problems noted. The attached picture is of the casing after
pullling on the abandonment - no thread galling or damage noted.
In addition, BG have investigated dope for RL-4S premium grade
connections for surface casing in a project with Vetco. This
resulted in the selection of a new, certified product. This has been
used on two wells so far, without problem.
