Oil major Shell said production has started from the Stones development in the Gulf of Mexico.
It is the world’s deepest offshore oil and gas project and is expected to produce around 50,000 barrels of oil equivalent per day when fully ramped up at the end of next year.
The facility being used for the project s a floating production, storage and offloading (FPSO) vessel.
Andy Brown, Upstream director, said: “Stones is the latest example of our leadership, capability, and knowledge which are key to profitably developing our global deepwater resources.
“Our growing expertise in using such technologies in innovative ways will help us unlock more deepwater resources around the world.”
Stones is 100% owned and operated by Shell and is the company’s second producing field from the Lower Tertiary geologic frontier in the Gulf of Mexico, following the start-up of Perdido in 2010.
