Oil and Gas

Participants will learn to:

1. Identify the key components of well planning, including pressure-depth plots, overburden, and fracture pressures.
2. Describe overpressure generating mechanisms and the relationship between shale and reservoir pressures.
3. Apply tools such as drilling data, logs, seismic velocities, and basin models for pore pressure prediction.
4. Explain the influence of geopressure on hydraulic seal failure, fault seal integrity, and reservoir quality.
5. Interpret overpressure mapping and hydrodynamics in relation to fill/spill dynamics and volumetrics.
6. Summarize the key factors affecting carbon storage capacity, including trapping criteria and pressure/temperature conditions in deep saline aquifers and depleted reservoirs.

This course is ideal for geoscientists, petroleum engineers, well planners, and drilling engineers involved in exploration, drilling, and reservoir management. It is also relevant for CCUS professionals working on carbon storage projects, reservoir and production engineers focused on performance optimization, and basin modelers integrating pressure data. Asset managers and decision-makers seeking to understand the impact of pressure data on oilfield development and carbon capture will also benefit.
