ABSTRACT:
Sulfonated polymers and copolymers are used as thinners in aqueous drilling or packer fluids. The sulfonated polymer has polydispersity below 2 and has a low solution viscosity. It is generally a copolymer of beta-arylamidoalkane sulfonate or allyl sulfonate or other aliphatic sulfonate with an ethylenically unsaturated carboxylic acid, generally acrylic acid.
