Proven Exploration Outcomes. Strategic, Safe, Sustainable.
We convert subsurface insight into measurable value discovery-led exploration assurance, portfolio optimization, and ESG-aligned transition planning that reduces risk and accelerates decisions.
Deepwater Delta Field – Exploration Optimization Success
We were engaged to assess two undeveloped oil and gas discoveries in a complex deepwater deltaic environment. The client sought a technical and strategic review to optimize exploration potential and identify infield opportunities.
Our Approach
Our team applied a regional depositional model integrated with seismic interpretation and well correlation to build a robust exploration framework. By harmonizing subsurface models with regional stratigraphy, we established new hydrocarbon-bearing equivalents and generated fresh exploration leads within the block.
Key Steps
1. Performed regional correlation and depositional modeling using multiple seismic vintages.
2. Conducted reservoir quality evaluation and hydrocarbon system validation.
3. Applied environment of deposition modeling to confirm lead maturity and optimize future drilling campaigns.
Results
1. dentification of over 200 million barrels of recoverable oil and 1.5 trillion cubic feet of natural gas equivalents.
2. Development of a new exploration assurance workflow that increased discovery confidence.
3. Enhanced understanding of reservoir continuity and new step-out opportunities across the block.
Salt Basin Carbonate Play – Pressure and Risk Management
In a high-pressure carbonate play within a salt-bounded basin, the client faced operational uncertainty due to overpressure risks and poor seismic imaging. We were tasked to lead exploration assurance and risk management.
Our Approach
We developed a pressure prediction model integrating regional geological data, seismic velocity models, and well calibration to mitigate drilling risks. A focus was placed on maintaining well integrity, optimizing drilling design, and improving data reliability through rigorous QA/QC protocols.
Key Insights
1. Detailed risk bubble mapping covering technical, economic, and organizational risks.
2. Pressure prediction and modeling to guide mud weight design and prevent well control incidents.
3. Seismic reinterpretation to reduce depth uncertainty and define target zones more accurately.
Results
1. Successful discovery of a major gas-condensate field, with over 400 billion cubic feet of gas reserves and significant condensate yield.
2. Established a best-practice framework for exploration assurance, now used in subsequent basin developments.
3. Demonstrated the value of integrating subsurface, HSE, and governance insights for safer, more profitable exploration.
