Styrenic block copolymers as thermally-activated viscosifiers for oilfield applications |
| abstract |
Provided herein is a dispersion composition comprising a blend of a semi-crystalline, selectively hydrogenated block copolymer and a low polarity fluid for oilfield applications. The block copolymer comprises blocks of semi-crystalline hydrogenated polybutadiene, blocks of poly(mono alkenyl arenes), and blocks of hydrogenated, non-crystalline conjugated dienes. The dispersions can be converted to thixotropic fluids or cohesive gels and find application as insulating packer fluids, fluid loss pills, drilling fluids and completion fluids. |
