摘要：Major blowouts in Krishna-Godavari (KG) basin have led to number of risks related to loss of human lives, environmental pollution and loss of material assets. The geological complexity of the field and the presence of over pressure zones, mainly in East Godavari sub-basin, particularly in the wells at Amalapuram, Razole and Narsapur have led to major disasters in the past years. Therefore, an attempt has been made to identify the most possible causes of these disasters and to propose a safe drilling procedure to prevent these disasters in the upcoming ventures. This paper highlights the case study of a blowout occurred in KG basin in East Coast of India. An analysis of the blowout was carried out which includes well configuration and details, mechanical equipment used for controlling the blowout, firefighting procedures, financial losses incurred. The effect of exploration and production of oil and gas on the property and environment were also discussed. Efficient drilling and safety procedures were recommended to prevent further blowouts in future. The recommendations presented will be of utmost importance for oil and gas operators and service companies to take necessary steps in future drilling operations in over pressured formations of KG basin to prevent loss to personnel, property and damage to the environment.
