- By contacting with water, the product undergoes hydrolytic polycondensation followed with formation of water-repellent solid polyorganosiloxanes with cross-linked structure in the well bottom zone.
- The formed polyorganosiloxanes show a high water-shutoff capacity.
- The product is used for selective water shutoff in oil wells at temperature over the range 0-200ºC.
