Abstract:
Methods and materials for treating completed oil and gas wells that have been partially depleted as a prelude to refracturing are provided. These methods include: (a) preparing a polyurethane diverting agent by mixing a polyol-containing component and a polyisocyanate-containing component; and (b) introducing the polyurethane diverting agent into the well. The polyol-containing component includes a polymeric polyol having a viscosity at 25° C. of no more than 1000 mPa·s and the isocyanate-containing component includes an unblocked (cyclo)aliphatic polyisocyanate polymer, optionally including allophanate groups, and having a viscosity at 25° C. of no more than 1000 mPa·s and at least 99% solids content.

Claim (Index 3):
The method according to  claim 2 , wherein the polyalkoxylated triol comprises a polypropylene-oxide triol.
