Seria Field

Wells

• S-1 was the first exploration well, drilled in July 1928, which began producing oil in April 1929.
• S-2 was brought on stream in 1930. After two blow-outs followed by shutdowns and deliberate sabotage during the war years, it settled to a steady flow on gas-lift and proved to be a valuable producer.
• S-5, which is still producing and is the earliest well still in production in Seria 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.
