Key facts

Location: Gulf of Mexico, USA
Depth: 914 metres (3,000 feet)
Interests:   Shell (71.5% & operator) and BP (28.5%)
Field: Mars
Design capacity: 100,000 bbl/d

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. This  should extend the life of the greater Mars basin to 2050 or beyond.

First oil production from Mars B began in February 2014 through Olympus, Shell’s seventh, and largest, floating deep-water platform in the Gulf of Mexico.

In addition to the Olympus drilling and production platform, the Shell Mars B development includes subsea wells at the West Boreas and South Deimos fields, export pipelines, and a shallow-water platform located near the Louisiana coast. 

Olympus is located in about 945 metres (3,100 feet) of water.  

The Mars field has been one of Shell’s most important fields over the past 20 years. When we discovered the field in 1989, we estimated that it would have nearly 700 million boe of resources. To date the field has produced more than 850 million boe.

Environment and society

During the project’s development and operations, Mars B will generate opportunities for the Gulf of Mexico region through the creation of jobs, revenues and better infrastructure.

Shell is also investing $5m in community and environmental initiatives, partnering with groups that include The Nature Conservancy, Barataria-Terrebonne National Estuary Program, and LA-1 Coalition.
