Abstract
It has been determined that sealant fluid formulations comprising a lubricant oil derived from Fischer-Tropsch waxes demonstrate performance comparable to sealant fluid comprising lubricants derived from polyalphaolefins (PAO's). The sealant fluids of the current invention can provide excellent performance properties similar to those provided by PAO based sealant fluids, but at lower cost.
