The Favorable Geological Conditions for Air Foam Drilling
Abstract:
Air foam drilling is adopted generally for its high rate of penetration, lower pollution to the reservoirs and low costs. Only when there are low formation pressure, long interval favorable formation, clear non-gas or non-oil formation and lower pay zone, air foam drilling can realize its advantages including maximum increasing rate of penetration, protecting reservoir and lowing the cost.
