ABSTRACT:
A method is presented for cementing conductor pipes in well bores in water depths greater than 1000 feet. The method is accomplished by formulating the cement slurry from Portland cement, a foaming surfactant, a quantity of fine particle size cementitious material and nitrogen or other gas to foam the slurry to yield a density of from about 9.0 to about 14 lbs/gal. The slurry is introduced down the conductor pipe and permitted to return up the annulus of the well bore to the seafloor. The slurry develops a static gel strength in excess of about 500 lbf/100 ft.sup.2 within less than about 30 minutes after placement.
