Production loss in most wells starts near the wellbore. Drilling fluids, completion fluids, fines migration and scale deposition all restrict flow long before the reservoir itself is depleted. This workshop explains how that damage forms, how to recognise it from well data, and what to do about it — covering the mechanisms behind well stimulation, the main treatment types and where each applies, how to select candidate wells, how formation damage shows up in the skin factor, and why scale deposits and how it is removed in the field. The session is built around field experience and real well cases rather than theory alone.

Workshop Objectives

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


Explain the objectives and physical mechanisms behind well stimulation treatments


Compare the main stimulation techniques and identify where each one is appropriate


Apply candidate selection criteria to decide which wells justify a stimulation treatment


Identify the causes and types of formation damage across drilling, completion, production and injection operations


Interpret skin factor and separate formation damage from mechanical and completion effects


Describe the conditions that drive scale deposition and recognise the common oilfield scale types


Assess the production impact of scale and select a suitable removal method


Apply field-proven scale removal procedures and understand their operational limits


Use case study evidence to support stimulation decisions in their own assets

About the Presenter

Peyman Daneshfar is an accomplished Well Stimulation Engineer with over 11 years of experience in the oil and gas industry.

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.
