Course Overview

This program trains participants in the unique challenges and techniques of applying EOR methods to naturally fractured reservoirs. It covers fundamentals of NFR behavior, screening EOR processes, modeling dual-porosity systems, field implementation strategies, and performance monitoring of EOR projects in fractured reservoirs.

Day-by-Day Outline

Day 1 – Fundamentals of Naturally Fractured Reservoirs

Types of fractures and fracture networks
Dual-porosity and dual-permeability systems
Flow dynamics: matrix-fracture interaction
Primary and secondary recovery in NFRs
Exercise: Analyze core and well data for fracture characterization

Day 2 – Screening EOR Methods for NFRs

EOR techniques overview: gas injection, WAG, foam, polymer gels, thermal
Selection criteria for fractured reservoirs
Challenges of matrix block size, wettability, and capillary forces
Field examples of successful and failed EOR pilots
Workshop: Screen EOR options for different fractured reservoir scenarios

Day 3 – Gas and Miscible Flooding in NFRs

CO₂ injection mechanisms in NFRs
Immiscible vs. miscible gas flooding
Gravity drainage and gas-oil gravity drainage (GOGD)
Monitoring and controlling gas conformance
Exercise: Calculate incremental recovery for CO₂ flooding in an NFR

Day 4 – Thermal and Chemical EOR in NFRs

Thermal EOR processes: steam flooding, cyclic steam, in-situ combustion
Feasibility of thermal methods in fractured carbonates
Polymer and surfactant methods in fractured systems
Challenges of sweep efficiency and fracture conformance
Workshop: Evaluate thermal and chemical EOR case studies in NFRs
