ABSTRACT:
The present invention provides improved methods of sealing a subterranean zone to remedy the uncontrolled flow of fluids into and out of the zone. The methods basically comprise preparing a sealing composition and placing the composition into the zone to be sealed. The placement of the composition is controlled in a manner whereby portions of the sealing composition are continuously converted to sealing masses which are successively diverted into permeable portions of the zone until all of the permeable portions are sealed.
