| 20110315402 | METHOD FOR FORMING AN ISOLATING PLUG - 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. | 12-29-2011 |
