INTRODUCTION

Clastic reservoirs represent some of the most important hydrocarbon-bearing systems in oil and gas fields worldwide. Their performance depends strongly on depositional facies, grain size, sorting, sedimentary structures, stratigraphic continuity, diagenesis, and reservoir architecture. Accurate facies interpretation is essential for predicting reservoir distribution, quality, connectivity, barriers, baffles, and flow units. This course introduces participants to practical methods for analyzing clastic reservoir facies and translating geological understanding into reservoir models. It explains how core observations, well logs, seismic data, production information, and depositional concepts are integrated to describe subsurface complexity. Participants examine clastic environments such as fluvial channels, delta systems, shoreface deposits, deepwater fans, and turbidite complexes. The program focuses on applied workflows that support static modeling, property population, uncertainty management, and reservoir development decisions. It also highlights collaboration between geology, petrophysics, geophysics, and reservoir engineering for stronger model reliability. This course provides a structured pathway for professionals seeking to improve reservoir characterization and modeling outcomes in clastic fields.
