Petrobras Requests Authorization to Include Constellation Drilling Rig in Exploration of the Foz do Amazonas Basin

May 1 – Petrobras has requested authorization from IBAMA (Brazilian Institute of Environment and Renewable Natural Resources) to use the Amaralina Star (NS-43) drillship, owned by Constellation, in exploratory activities in block FZA-M-59, in the Foz do Amazonas Basin. This measure aims to increase operational flexibility in the Equatorial Margin, allowing for optimized resource allocation in the region’s exploration campaign.

As a reminder, in December 2024, Petrobras contracted the Amaralina Star drilling rig in an agreement worth approximately US$528 million. The contract came into effect in March of this year and will last for three years, with an option for extension for up to 315 days, subject to mutual agreement.

The Amaralina Star is a 6th generation dynamically positioned drillship, designed to operate in water depths of up to 10,000 feet and drill at depths of up to 40,000 feet. Currently, Petrobras is drilling the Morpho pioneer well in the block, using the ODN-II rig from Foresea.
