Most production engineering calculations don't need expensive software — they need Excel used well. This live 2-hour beginner workshop shows you how to build the core tools of well performance analysis directly in a spreadsheet. You'll create working models for inflow performance, nodal analysis, and decline curves from scratch, using nothing but Microsoft Excel — so you understand what's happening under the hood instead of treating commercial software as a black box.

Workshop Objectives

By the end of this workshop, you will be able to:


Build Inflow Performance Relationship (IPR) curves and understand what drives well deliverability


Set up nodal analysis to find a well's operating point and diagnose performance


Run decline curve analysis to forecast production and estimate recoverable reserves


Turn raw well data into clean, decision-ready charts and models in Excel

About the Presenter

Mostafa Keihani is a Production Engineer at Dana Energy, where he has spent the past four years across production engineering and field operations, including work as a Cementing and Stimulation Field Engineer. That mix gives him a practical, field-grounded view of well performance — not just the theory, but how it plays out on real wells.


He holds engineering degrees from Sharif University of Technology and Amirkabir University of Technology, and is the author and co-author of several peer-reviewed publications. His technical focus spans production optimization, enhanced oil recovery, well stimulation, and carbon capture (CCUS). He brings both hands-on field experience and a strong analytical background to this workshop, built for engineers who want to actually use what they learn.

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.
