ABSTRACT:
A permeable consolidated gravel pack is placed in a borehole adjacent an incompetent formation by first emplacing a self-breaking gel in the formation to temporarily plug the formation, and then injecting a slurry of treated particulate matter, e.g. resin coated sand, to form the consolidated gravel pack. The method is particularly useful for the treatment of incompetent formations having unusually low pressures and high permeabilities.
