An exclusive three-day live masterclass designed for practicing petroleum engineers and reservoir specialists who want to go beyond textbook theory. Covering commercial maturity of reservoirs, environmental economics in oil & gas, and polymer flood diagnostics, this masterclass brings four decades of real field experience into your screen — in just 90 focused minutes a day. Available only to PEA Members.

Workshop Objectives

By the end of this three-day masterclass, participants will be able to:


Understand why technically sound reservoirs fail to achieve commercial reserve status — and what engineers can do about it


Evaluate the economic and regulatory implications of carbon externalities and carbon tax on oil & gas operations


Identify key field indicators to assess whether a polymer flood is performing as designed


Apply lessons from real-world case studies to their own reservoir and production challenges


Engage directly with an industry veteran with 40+ years of hands-on experience across major operators

About the Presenter

Mr. Biswajit Choudhury is a seasoned Reservoir Engineering Consultant with over 40 years of experience across some of the world's most respected oil and gas organizations, including Shell International, PDO (Petroleum Development Oman), BG Group, and Oil India Limited. A graduate of IIT (ISM) Dhanbad, he has authored 12 peer-reviewed journal publications and has worked across exploration, development, and production phases in multiple global basins.


His career spans reservoir characterization, field development planning, enhanced oil recovery, and reserve estimation — giving him a uniquely integrated perspective that bridges technical rigor with commercial reality. Mr. Choudhury brings that depth directly into the classroom, making complex reservoir concepts accessible, practical, and immediately applicable.

Material Balance Modeling
November 28, 2026 - November 29, 2026
Material Balance Modeling

Material balance is one of the most direct methods available to a reservoir engineer for estimating hydrocarbons in place, identifying the drive mechanism and forecasting reservoir performance. It requires far less data than a full numerical model, and when it is set up correctly it produces results that can be defended in technical reviews and reserve audits.This workshop covers the complete material balance workflow as it is applied on producing assets. It begins by placing the reservoir within the integrated production system, then moves through data preparation and quality control, tank model construction, drive mechanism identification, and the use of analytical and graphical diagnostic tools. Participants work through the classical diagnostic plots, including Dake and Campbell, and learn how to read what each plot indicates about depletion, gas cap expansion and water influx.The second part of the workshop addresses history matching using both analytical and graphical techniques, determination of STOIIP, aquifer identification and sizing, and running prediction cases to generate production forecasts and recovery estimates. Results are compared against volumetric and simulation-based estimates so that participants understand where material balance is reliable and where a numerical model becomes necessary.The workshop is delivered at an advanced level and is intended for engineers who already work with production and pressure data and want a structured, repeatable method for in-place volumes, drive mechanism evaluation and performance prediction.
