Pore Pressure Analysis
Duration: 5 Days
Target Audience: Drilling Engineers, Well Planners, Geologists, Geophysicists, Mud Loggers, Pore Pressure Specialists
Delivery Mode: Classroom / Virtual with Practical Exercises and Real Data Interpretation
Level: Intermediate
Course Overview
This hands-on course trains participants to predict, detect, and interpret pore pressure in the subsurface, which is critical for safe and cost-effective drilling. It covers pressure mechanisms, wellbore stability, detection methods, and integration of seismic and well data for accurate pore pressure prediction and management.
Day-by-Day Outline
Day 1 – Fundamentals of Pore Pressure
- Concepts of overburden stress, pore pressure, effective stress
- Causes of abnormal pressure: undercompaction, fluid expansion, tectonic effects
- Pressure regimes: normal, subnormal, overpressured
- Introduction to fracture gradients
- Exercise: Calculate overburden and effective stress profiles
Day 2 – Pore Pressure Prediction from Well Logs
- Resistivity, sonic, and density log responses to pressure changes
- Eaton’s and Bowers’ methods for pressure estimation
- Identifying pressure transition zones on logs
- Case examples of log-based pressure detection
- Workshop: Apply Eaton’s method to a real well log dataset
Day 3 – Seismic-Based Pore Pressure Prediction
- Velocity analysis for pore pressure prediction
- Deriving interval velocities from seismic stacking velocities
- Calibrating seismic velocity models with well data
- Limitations of seismic-based methods
- Exercise: Build a velocity-to-pressure model from synthetic seismic data
Day 4 – Real-Time Pressure Detection While Drilling
- Surface and downhole indicators of abnormal pressure
- Gas readings, cuttings analysis, pit gains/losses
- Equivalent circulating density (ECD) monitoring
- Kick detection and well control basics
- Workshop: Interpret mud logging data for pressure warning signs
Day 5 – Integrating Pore Pressure into Well Planning
- Building a comprehensive pore pressure and fracture gradient model
- Mud weight program design
- Wellbore stability considerations
- Pressure prediction uncertainty and risk assessment
- Capstone Project: Create a pore pressure prediction report with recommended mud weights for a planned well
