Reservoir Quality Analysis of Sandstone & Carbonate Rock Types

Introduction

This GLOMACS Reservoir Quality Analysis  of Sandstone & Carbonate Rock Types training program is designed to provide comprehensive guidance to geologists working in the oil industry on understanding the characteristics of sandstone and carbonate rocks relevant to reservoir quality. Through reservoir quality analysis, participants will learn to discern the primary factors influencing porosity and permeability evolution in sandstone and carbonate reservoirs, including depositional processes, provenance, and diagenetic changes (such as porosity evolution with burial depth, mineral composition, and diagenetic settings). Case studies from both sandstone and carbonate hydrocarbon reservoirs will be explored to enhance understanding.

This Reservoir Quality Analysis  of Sandstone & Carbonate Rock Types training course will highlight:

• Introduction to siliciclastic and carbonate reservoirs, focusing on factors influencing reservoir quality.
• Understand sandstone characteristics including composition, origin, diagenesis, and geological settings.
• Understand carbonate features such as constituent types, classification, and diagenetic processes.
• Conduct petrographic analyses (thin sections, scanning electron microscopy, cathodoluminescence), X-ray diffraction, QEMSCAN, and integrating results to assess reservoir quality.
• Classify porosity, examining its evolution relative to burial depth, stratigraphy, composition, authigenic elements, and diagenetic environments.
• Discussing the concept of rock typing, various schemes for categorizing rocks, and analyzing uncored reservoir sections.

Objectives

By the end of this Reservoir Quality Analysis  of Sandstone & Carbonate Rock Types training course, participants will:

• Gain insight into the diverse sandstone hydrocarbon reservoir types and their primary influences on reservoir quality.
• Acquire knowledge regarding the various types of carbonate reservoirs and the key factors affecting reservoir quality.
• Develop the ability to distinguish between depositional, provenance, and diagenetic indicators in analyzed sandstones and carbonates.
• Be capable of integrating and interpreting porosity-permeability data in relation to stratigraphy and regional geology.
• Comprehend the principal rock-based methodologies utilized in reservoir quality analyses.
• Familiarize with the concepts of rock typing and conducting petrophysical comparisons between cuttings and core samples.

Training Methodology

This training course is based in PowerPoint presentations, numerous real-world examples and practical sessions with exercises. Examples of thin sections, SEM and CL analyses are also presented to understand the workflow to integrate different methodologies used for reservoir quality evaluation. 

Clients are encouraged to provide examples of reservoirs their companies are working with so that the data is reviewed and potentially new methodologies and solutions to their reservoir problems can be discussed.
