Abstract
The present invention relates to improved methods and compositions for performing well completion or remedial procedures in subterranean zones having temperatures below about 70.degree. F. The methods basically comprise the steps of introducing into the zone an aqueous solution of a polymerizable monomer, a polymerization initiator and an oxygen scavenger comprised of stannous chloride. Thereafter, the polymerizable monomer is allowed to polymerize in the zone. The stannous chloride scavenges oxygen without generating free radicals and causing premature polymerization.
