Naturally Fractured Reservoirs (NFRs)

Duration: 5 Days
Target Audience: Geologists, Reservoir Engineers, Geophysicists, Petrophysicists, Production Engineers
Delivery Mode: Classroom / Virtual with Hands-On Exercises and Case Studies
Level: Intermediate

Course Overview

This course provides an integrated understanding of naturally fractured reservoirs, their characterization, modeling, and production behavior. Participants will learn how fractures impact reservoir performance, techniques to detect and quantify fractures from cores, logs, and seismic data, and methods for modeling and managing NFRs.

Day-by-Day Outline

Day 1 – Introduction to Naturally Fractured Reservoirs

Definition and types of fractures
Fracture genesis: tectonic, diagenetic, and stress-related
Key differences between matrix-dominated and fracture-dominated reservoirs
Rock mechanics concepts for fractures
Exercise: Identify fractures in core images and thin sections

Day 2 – Fracture Detection and Characterization

Fracture analysis from outcrops and cores
Borehole image logs: FMI/OBMI interpretation
Well log signatures of fractures (resistivity, sonic, density)
Core-log integration for fracture characterization
Workshop: Interpret fracture patterns from borehole images

Day 3 – Seismic and Geomechanical Methods

Seismic attributes for fracture detection
Azimuthal AVO and anisotropy for fracture orientation
Building geomechanical models for stress analysis
Natural fracture prediction from structural and mechanical properties
Exercise: Map fracture trends using seismic attributes

Day 4 – Flow Behavior and Modeling of NFRs

Dual-porosity and dual-permeability concepts
Transient flow regimes in fractured reservoirs
Matrix-fracture interaction and storage capacity
Upscaling fractures for reservoir simulation
Workshop: Build a simple dual-porosity model

Day 5 – Field Development Strategies and Case Studies

Well placement and completion strategies in NFRs
Stimulation techniques in tight and fractured formations
Production monitoring and decline analysis in NFRs
Case studies: carbonate and clastic fractured reservoirs
Capstone Project: Develop a field development plan for an NFR
