Shelf Drilling is working closely with Transocean under a transition services agreement to ensure a safe and seamless transition.

Shelf Drilling is headquartered in Dubai with locations in Southeast Asia, India, West Africa, Egypt, Saudi Arabia and Italy. With a sole focus on shallow water drilling, and many of the world's leading oil companies as customers, Shelf Drilling is positioned to become a significant player in the market from day one. Customers include Chevron, ExxonMobil, ONGC, Perenco, Petrofac, Saudi Aramco and Total.

Shelf Drilling has three core strategic priorities:


Shallow water drilling is Shelf Drilling's sole focus, with a flat, operationally- focused organization dedicated to outstanding customer service.


With safety at the forefront of everything we do, Shelf Drilling creates an incident-free environment where no one gets hurt. We deliver outstanding performance through continued investment in our people and maintaining our rigs to the highest reliability and quality levels.


Shelf Drilling's goal is to develop long-term and mutually beneficial relationships with customers and suppliers and to be the shallow water drilling contractor of choice.
