Course Introduction

Reservoir characterization is a critical component to understanding the variety and causes of compartmentalization of structural or stratigraphically complex reservoirs. This 5 day course examines the various techniques for characterizing clastic reservoirs. Emphasis is placed on the variety of styles and causes of compartmentalization of reservoirs and associated development and production issues. Integrated characterization is emphasized. Topics include the measurement and analysis of static and dynamic reservoir properties, geologic controls on reservoir quality (porosity and permeability), flow unit characterization for upscaling, high-frequency sequence stratigraphy for characterization, styles of stratigraphic traps and compartments, structural compartmentalization, principles of geologic modeling for simulation and use of borehole image tools in the characterization of reservoirs. A case study approach is used throughout to explain the various topics. In-class exercises are completed to demonstrate and principles and techniques

Course Objective

• Understand the variety of clastic reservoir types and why they form different types of reservoirs.
• Achieve a general level of knowledge in recognizing the criteria (rock, log, seismic) which differentiate the variety of clastic reservoir rocks.
• Understand the controls on reservoir performance of these different heterogeneity.
• Learn the scales and types of heterogeneity that comprise clastic reservoirs
• Apply knowledge of clastic reservoir to reservoir management and well planning

Suitable For

Geologists and geophysicists who are beginning involvement in reservoir characterization or who want to broaden their experiences beyond exploration; petroleum engineers who want to improve their understanding of the geologic aspects of oil and gas reservoirs.

Training Methodology

A highly interactive combination of lecture and discussion sessions will be managed to maximize the amount and quality of information, knowledge and experience transfer. The sessions will start by raising the most relevant questions, and motivate everybody finding the right answers. The attendants will also be encouraged to raise more of their own questions and to share developing the right answers using their own analysis and experience.

All presentations are made in excellent colorful power point. Very useful Course Materials will be given.

• 30% Lectures
