Abstract
Restoration of drilling mud-pits which have served for purification treatment of drilling effluents in the search for hydrocarbons on terra firma by covering the floc of the mud-pit with a layer of water-absorbent material, particularly a natural cellulosic material, before filling the hollow or basin in with earth. The process makes it possible to firmly stabilize the refilled ground and make it cultivatable; it represents a substantial economy over known methods.
