Course Overview

Day-by-Day Outline

Day 1 – Fundamentals of Well Siting

• Principles of well location selection
• Integrating subsurface data: seismic, logs, and maps
• Structure maps, isopach maps, and reservoir geometry
• Regulatory, surface, and environmental considerations
• Exercise: Select optimal well locations on a prospect map

Day 2 – Geological Well Planning

• Geological prognosis and well proposals
• Expected formations, tops, and thickness estimates
• Drilling hazards identification (overpressure zones, faults)
• Mudlogging and coring plan
• Workshop: Build a geological prognosis for a planned well

Day 3 – Operational Geology at the Wellsite

• Roles and responsibilities of a wellsite geologist
• Description and interpretation of cuttings and cores
• Lag time, lithology logs, and gas readings
• Real-time data monitoring and communication with drilling teams
• Exercise: Describe cutting samples and update lithology logs

Day 4 – Geosteering and Real-Time Decision Making

• Basics of directional drilling and horizontal wells
• Geosteering techniques using LWD/MWD data
• Adjusting well trajectory to stay in target zones
• Integrating gamma ray, resistivity, and images in geosteering
• Workshop: Interpret LWD data for real-time trajectory adjustment

Day 5 – Post-Well Analysis and Reporting

• Comparing geological prognosis vs. actual results
• Updating geological maps and reservoir models
• Lessons learned and operational improvements
• Final well report preparation and data archiving
• Capstone Project: Complete a well summary report including prognosis vs. outcome analysis

Expected Learning Outcomes

• Select optimal well locations integrating geological and operational factors
• Prepare detailed geological well prognoses
