Reservoir management is the discipline that connects everything else. Individual studies, log interpretation, well tests, simulation runs, laboratory reports, only create value when they feed into a coherent plan for how a field is developed, operated and monitored over its life. Fields underperform far more often because of poor integration and weak surveillance than because of any single technical error.


This workshop covers the reservoir management cycle as it is practised on producing assets. It begins with oilfield development and data management: what data needs to be collected, how it is validated and stored, and how data quality affects every decision taken downstream. Formation evaluation and reservoir characterisation follow, covering the integration of petrophysical, core, geological and engineering data into a consistent reservoir description.


The workshop then addresses reserves estimation across the available methods, volumetric, decline curve analysis, material balance and simulation, including the conditions under which each is reliable, how the results should be reconciled, and the classification and reporting framework used for reserves.


Well testing is treated from the reservoir management perspective: what information a well test contributes to the field picture, how test results are used to update the reservoir description, and how a testing programme should be planned across an asset rather than well by well.


The final section covers waterflood management and surveillance. This includes the design of a surveillance plan, the routine data that should be collected, the diagnostic plots and monitoring tools used to judge performance, and the process for identifying underperformance and defining corrective action, whether that is infill drilling, recompletion, workover, water shut-off or stimulation.


The workshop is delivered at an advanced level and is intended for reservoir engineers, production engineers and asset team members responsible for field performance.

Workshop Objectives

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


Describe the reservoir management cycle and the role of each discipline within an integrated asset team


Define the data requirements for effective field development and apply data management and quality control standards


Integrate petrophysical, core, geological and production data into a consistent reservoir characterisation


Apply volumetric, decline curve, material balance and simulation methods for reserves estimation and reconcile the results


Classify and report reserves in line with recognised industry guidelines


Plan a well testing programme at asset level and apply test results to update the reservoir description


Design and implement a reservoir surveillance plan, including pressure surveys, production logging and well testing


Manage a waterflood using voidage replacement, injection allocation and injected water quality control


Apply standard diagnostic plots and monitoring tools to evaluate reservoir and well performance


Identify underperforming wells and reservoir zones and recommend appropriate remedial action, including infill drilling, recompletion, workover, water shut-off and stimulation


Track field performance against the development plan and revise the plan as new data becomes available

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.
