ABSTRACT:
The present invention relates to novel crosslinkable interpolymers and methods of use in treating subterranean formations. The novel interpolymers comprise a water soluble monomer, a hydrophobe monomer, and vicinal diol monomer polymerized to form high molecular weight polymers which viscosify aqueous liquids. The solution viscosity may be enhanced by the addition of a surfactant having an HLB value of about 10 or less. The interpolymers are readily crosslinkable with polyvalent metal ions, such as titanium and zirconium to form thermally stable viscoelastic gels. The gels provide viscosity and solids transport characteristics that are useful in stimulating, gravel packing and polymer flooding operations.
