After discovering an additional 400 million barrels of oil at the field, BP aims to start its production of 8 new wells which will add 38,000 barrels per day to the company’s total output at the Atlantis field by 2020.

The oil giant also announced new discoveries at the Nearly Headless Nick prospect near the Na Kika platform located northeast of Thunder Horse, where the company holds a 20.25% working interest.
