Progress in offshore development starts with early alignment and trusted ex*****on.

At Offshore Technology Conference Asia, discussions reinforced a shared priority: aligning on common objectives early to deliver stronger decisions and long-term value. Digital capabilities play a critical role in strengthening readiness and supporting disciplined ex*****on at scale.

Notable discussions and developments included:

• Customers underscored the importance of transparent communication to support consistent performance across offshore operations.

• Shannon Slocum, executive vice president and chief operating officer, shared leadership perspectives on decision-making in complex and demanding environments.

• A strategic collaboration was announced with PETRONAS and Valaris Limited to advance offshore development through integrated planning and high-quality ex*****on.

Additional momentum was reflected through industry recognition for advancements in drilling fluids and subsurface visualization. An MOU with Prime Energy further supports cost-effective deepwater exploration and development through delivery-focused collaboration.
