Field. S-328 was drilled in 1953 with a blow-out. With a power of a minor earthquake, it demolished an adjacent building and left a crater flooded with water. S-454 was spudded in the middle of a housing area. S-516 was drilled in 1956 with a serious blow-out. A jet of oil, gas and sand rose over 30 meters into the air, and the well had to be 'killed' with 90 tonnes of mud and plugging material. S-558 was drilled in 1964 across the road from Brunei Shell's head office. References Further reading Brunei Shell Petroleum, 1988, The Billionth Barrel Seria Oilfield Sandal, S. T.
