Deciphering Reservoir Dynamics: Well Test Design and Analysis Training Course

Introduction

Well testing is a fundamental and powerful diagnostic tool in petroleum engineering, providing crucial insights into reservoir properties, well performance, and connectivity. By systematically varying production or injection rates and observing the resulting pressure responses, engineers can infer critical parameters such as permeability, skin factor, reservoir boundaries, and fluid contacts. Accurate well test design and rigorous analysis are indispensable for making informed decisions throughout the exploration, appraisal, and development phases of an oil and gas field.

This intensive training course is meticulously designed to equip participants with a comprehensive and practical understanding of well test design and analysis. From exploring the fundamental principles of fluid flow in porous media and various well test types to mastering pressure transient analysis techniques, interpreting diagnostic plots, and utilizing industry-standard software, you will gain the expertise to effectively characterize reservoirs. This empowers you to optimize well performance, predict future production, manage reservoir uncertainties, and strategically contribute to maximizing hydrocarbon recovery.
