ABSTRACT:
Organophilic polymer adducts which are effective fluid loss control additives for oil base well-working fluids are prepared from an anionic or cationic water soluble polymer and one or more phosphatides. Preferred phosphatides are phosphoglycerides obtained from vegetable oils, most preferably commercial lecithin. Preferred polymers comprise polysaccharides or derivatives thereof and synthetic polymers.
