Enhanced Oil Recovery with Gas Injection (EORG)
Duration: 5 Days
Target Audience: Reservoir Engineers, EOR Specialists, Production Engineers, Development Planners
Delivery Mode: Classroom / Virtual with Practical Design Exercises and Case Studies
Level: Intermediate to Advanced
Course Overview
This program focuses on advanced techniques of gas-based enhanced oil recovery (EOR), including miscible and immiscible processes using CO₂, hydrocarbon gases, or nitrogen. Participants will learn about displacement mechanisms, screening criteria, injection design, monitoring, and performance evaluation of gas injection projects.
Day-by-Day Outline
Day 1 – Fundamentals of Gas-Based EOR
- Principles of miscible and immiscible gas flooding
- Minimum miscibility pressure (MMP) and its determination
- Vaporizing and condensing gas drive mechanisms
- CO₂, hydrocarbon gas, and N₂ injection processes overview
- Exercise: Analyze phase diagrams to determine miscibility conditions
Day 2 – Screening and Feasibility Analysis
- Reservoir and fluid properties favoring gas EOR
- Screening criteria for miscible and immiscible injection
- Reservoir heterogeneity and conformance considerations
- Economic and environmental feasibility analysis
- Workshop: Screen candidate reservoirs for gas injection projects
Day 3 – Design of Gas Injection Projects
- Injection schemes: continuous gas injection, water-alternating-gas (WAG), simultaneous injection
- Determining injection rates and patterns
- Compositional simulation of gas injection displacement
- Surface facilities for gas compression and recycling
- Exercise: Design a gas injection schedule for a target reservoir
Day 4 – Monitoring, Surveillance, and Optimization
- Monitoring tools: pressure, tracers, time-lapse (4D) seismic
- Analyzing gas breakthrough and sweep efficiency
- Managing gas cycling and conformance issues
- Surveillance planning and decision-making workflows
- Workshop: Interpret surveillance data to optimize gas EOR performance
Day 5 – Case Studies and Risk Management
- Field case studies of successful and challenging gas injection projects
- Risk assessment in gas EOR implementation
- Safety and environmental considerations of gas injection
- Integrating gas EOR into field development plans
- Capstone Project: Develop a comprehensive gas EOR proposal for a candidate reservoir
