Prospects of Foam Stimulation in Oil and Gas Wells of India

摘要

This paper presents the scope of using “Foam Fracturing” technology in oil wells of India. Since the inception of foam stimulation technique in 1968, it has not been utilized/implemented in India despite of its various unique advantages. “Foam Fracturing” was very successful in Arkansas. 8 wells were drilled in the Pettit Limestone formation. Initial production averaged 4.8m3/d, but after 8 weeks, the production started to decline and the wells were stimulated with a 60-65% quality foamed acid. After treatment, the production enhanced to 6.6 to 11.4 m3/d. This paper consist many other examples of success of “Foam Fracturing” technology in wells of different regions and state. The unique advantages of foam as frac-fluid are: 1. Exceptional flow-back and clean-up. 2. Reduced liquid volume. 3. Good proppant-carrying capabilities. 4. Less operation time.
