  • Method of preparing polymer-water emulsion and further settling a sticky polymer material in downhole environment
    Patent number: 9353307
    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

  • METHOD FOR FORMING AN ISOLATING PLUG
    Publication number: 20110315402
    Abstract: Method of the subject disclosure can be used in the oil and gas production industry, in particular, for plugging fractures in the near-wellbore zone during the fracturing fluid removal, as well as for plugging different kinds of fractures and branches in the casing. For formation of an isolating-plug, a catch is placed upstream of the point where the isolating plug shall be formed, so as to prevent the passing of fibers and to promote the forming of fiber aggregates. A fluid containing dispersed fibers is then injected into a well, and the catch is periodically opened to release the fiber aggregates and to allow their free flow to the location where the plug shall be formed.
