Statistical analysis of past kicks and blowouts occurred in a Middle Eastern oilfield

Abstract In 2017, blowouts and then explosions occurred in a Middle Eastern oilfield. A root cause of the incident is lack study investigation past kicks data. Therefore, as pioneer work region, data gathering analysis were made studied oilfield to learn lessons find gaps. Out 149 drilled wells, total 117 three (3) occurred. this work, list drilling parameters be considered suggested guideline for future works elsewhere. The statistical not only showed all exploration wells kicked which surprise, but it also that 39 out 146 (26.71%) experienced during reservoir drilling. large number development proved possibility kick occurrence low. predominant causes gas-cut mud insufficient weight indicates necessity using pressure while addition rate control systems wells. However, lost circulation was indicating low-weight fluids managed systems. direct role human error exists at least 60% field, shows great importance improved personnel training. Although 3.45% due improper hole fill-up tripping, should deemed trivial, taken seriously being blowout. 2.56% conversion 67% risk blowout explosion emphasize maintaining primary well efficient early detection Bullhead more commonly used method than standard methods; kill may always safe, its application revised.
