Copolymers and compositions containing copolymers having advantageous viscosity, friction reduction, dissolution, pH-stability, and temperature-stability are provided. These copolymers can be used as rheology modifiers for oil field applications.

Fast dissolving, water soluble, hydrophobically-modified polyelectrolytes

Drilling fluid compositions and methods of using them are described. The drilling fluid compositions comprise nanocomposites comprising core-shell morphology, wherein the core material comprises a nanoparticle having an average particle size of about 5 nm to 100 nm, and the shell material comprises a crosslinked polymer comprising acrylamide repeat units. The nanocomposites are effective fluid loss control agents when the drilling fluids are employed in mud drilling operations.

Drilling fluids and methods of use

Methods of treating a well bore within an underground formation are disclosed. These methods include: (a) preparing a treatment composition by mixing a polyol-containing component and a polyisocyanate-containing component; and (b) introducing the treatment composition into the well bore. The polyol-containing component includes a polymeric polyol having a viscosity at 25&#xb0; C. of no more than 1000 mPa&#xb7;s and the isocyanate-containing component includes an unblocked (cyclo)aliphatic polyisocyanate polymer including allophanate groups and having a viscosity at 25&#xb0; C. and at least 99% solids of no more than 1000 mPa&#xb7;s.
