Schlumberger, Interwell, Tendeka, TCO and Petroleum Technology Company (PTC) have all been handed four-year contracts for well completion equipment and services for the development.

The contracts, which are added to Halliburton’s four-year drilling services deal for six production wells and other wildcats and services, come with options for up to a further four years.

The Maria project is a complex tie-back with the wellstream going to Kristin and from there to Aasgard for storage and export, while Aasgard B provides gaslift and Heidrun supplies water for injection.
