Abstract
Drilling fluid composition adapted for solidification in a borehole and method for solidifying a drilling fluid in a borehole are provided. The drilling fluid composition comprises (1) a drilling fluid, (2) a crosslinking-effective amount of at least one reactive monomer wherein the at least one reactive monomer is a metal salt of an .alpha., .beta.-ethylenically unsaturated carboxylic acid, a monomethacrylic acid metal salt, an aromatic acid acrylate, an aromatic acid methacrylate, or mixtures thereof, and (3) a polymerization initiator.
