Oil and gas field chemicals |
| abstract |
A composition for conformance of an oil or gas field reservoir consists of (i) at least one non acidic ethylenically unsatured polar monomer such as acrylamide, and (ii) at least one copolymerisable ethylenically unsaturated ester such as an alkyl or aralkyl acrylate which is gelled in the reservoir using a polyvalent metal ion gelling agent such as a chromium or zirconium salt. |
