Abstract:

The invention relates to a gel used as a drag reducing slurry. The slurry is stored aboard a vessel and is pumped into the region of laminar flow adjacent the vessel to reduce drag. The slurry is a thixotropic media composed of a surfactant coating the individual particles of drag reducing polymer resin as well as an anionic surfactant and a carrier liquid. The slurry forms a micelle structure and thus has an extremely long shelf life.
