ABSTRACT:
Methods of drilling a well bore utilizing a circulating drilling fluid and subsequently disposing of the drilling fluid by converting it to a cementitious composition are provided. The methods basically comprise the steps of forming the drilling fluid with an aqueous suspension of condensed silica fume as a component thereof, drilling a well bore using the drilling fluid, activating the drilling fluid whereby it will subsequently set into a hard cementitious mass and placing the set activated drilling fluid in one or more desired locations whereby it sets therein.
