Workshop 17
Evolving Geohazards Assessment for Modern Offshore Drilling Methods Friday, June 12th|
Convenors
- Alistair Robertshaw (BP)
- Eric Cauquil (Total Energies)
- Oyvind Ruden (Shell)
- Tommaso Ciccarone (ENI)
Description
The Geophysical Site Survey industry established itself as a critical safety component in planning offshore drilling operations as Oil and Gas exploration and development accelerated through the 1970s and 80s. As a consequence, the number of incidents saw a rapid decline. Today, drilling activity continues to move into new basins, geologies, and water depths, with changing risk profiles, pushing boundaries in drilling technology. Meanwhile, the Geohazards Assessment process has remained fundamentally the same. This workshop aims to explore how operators, survey companies and regulators are evolving their data, analysis, and assessment practices to meet today’s challenges and ensure appropriate, industry-wide risk management and the safety of top-hole drilling operations.
The workshop will ask important questions, such as:
- How do industry guidelines and regulations align with top-hole drilling risk identification and management practices to deliver increasingly complex wells?
- What techniques could support a more predictive, quantitative, and integrated geohazards analysis to reduce the assessment uncertainty?
- How can technical advancement in geophysical data be further leveraged to enable this?
Sub-Topics that will be covered in the workshop:
- Industry guidelines and practices
- Offshore drilling technical developments and challenges
- Risks and Opportunities for Safe Well Delivery
- Top-hole / Shallow Hazards Assessment practices and requirements
- Evolutions in Geophysical technology and hazard analysis
