Abstract
Methods useful in oil and gas production include producing a degradable (hydrolysable) polymer emulsion for downhole operations by mixing a degradable (hydrolysable) polymer solution with a treatment fluid using intense stirring to produce a stable emulsion at surface conditions, and allowing the degradable (hydrolysable) polymer emulsion to controllably decompose in downhole conditions to produce droplets of sticky polymer
