Shell’s Mars B development is the first deep-water project in the US Gulf of Mexico to expand an existing offshore oil and gas field with significant new infrastructure, which should extend the life of the greater Mars basin to 2050 or beyond.

First oil production begun in February 2014 from the Mars B development through Olympus, Shell’s seventh, and largest, floating deep-water platform in the Gulf of Mexico. Combined production from Olympus and Shell’s original Mars platform is expected to deliver an estimated resource base of 1 billion barrels of oil equivalent (boe). 

The project is also directly investing $5 million dollars in community, social and environmental initiatives with the aim to benefit the communities of the US Gulf Coast, as well as in South Korea, where the hull of the Olympus platform was built.
