The company serves government-owned energy firms, publicly listed integrated oil companies, and independent exploration and production entities, with primary revenue from Saudi Arabia and operations spanning the Middle East, North Africa, Mediterranean (MENAM), Southeast Asia, India, West Africa, and the North Sea. Incorporated in 2012 under Cayman Islands law with management headquartered in Dubai, United Arab Emirates, Shelf Drilling maintains a fit-for-purpose model focused on shallow-water jack-up services, safety, and long-term customer relationships. In September 2024, it announced an agreement to acquire Shelf Drilling (North Sea) Ltd, consolidating its jack-up fleet and addressing funding needs; subsequently in August 2025, ADES International Holding's subsidiary agreed to acquire Shelf Drilling for approximately SAR 1.4 billion (US$379 million) in cash, adding 33 rigs to create a combined fleet of 83 units and expanding market presence, with the merger completing in late November 2025 subject to shareholder and regulatory approvals.
