First oil from Stampede

Delivered safely, ahead of schedule and under budget

On February 5, 2018, the safe delivery of first oil was achieved from the Stampede project, which CNOOC International holds a 25% non-operated interest in. Importantly, this milestone was achieved ahead of schedule and under budget. Now that development of the Stampede resources is underway, CNOOC International and its partners – Hess (operator), Union Oil Company and Equinor – are looking forward to steady production volumes from this asset in 2018 and beyond.

The Stampede field is one of the largest undeveloped sites in the Gulf of Mexico and is located in approximately 1000 metres (3,500 feet) of water. The facility’s gross production capacity is 80,000 boe/d and 40 million standard cubic feet of natural gas per day, amounting to approximately 300 million to 350 million boe in the project’s life span.

The Stampede field project is comprised of a storm-safe Tension Leg Platform (TLP), six production wells, four water injection wells and four power generators. Stampede’s first gas export is scheduled for Q2, while the first water injection is expected in Q3.

CNOOC International also holds a 21% non-operated working interest in Appomattox, a discovery located 129 kilometres (80 miles) off the coast of Louisiana in approximately 2,000 metres (7,000 feet) of water.

Operated by Shell Gulf of Mexico Inc., Appomattox is estimated to contain about 700 million barrels of oil equivalent of probable reserves. In May 2018, the Appomattox platform left Ingleside, Texas, for its final location off the coast of Louisiana, and production is expected to begin in 2019. The Appomattox field is complemented by our nearby non-operated Vicksburg, Gettysburg and Rydberg discoveries.
