Practical Reservoir Simulation
Premium Workshop
For PEA Members Only
A reservoir simulation model is only as useful as the decisions it supports. Many models are technically complete but never answer the question they were built for, either because the input data was not properly conditioned, the history match was forced rather than earned, or the prediction cases did not reflect real operating constraints.
This workshop takes participants through the practical construction and use of a dynamic simulation model, following the sequence an engineer actually works in. It begins with the structure of the simulation input deck and the role of each section, then covers fluid and rock physics modeling, model initialisation and the calculation of dynamic in-place volumes, including how these are checked against volumetric and material balance estimates.
The workshop then addresses static model review and quality control: assessing 3D grid geometry, property distributions and upscaling before the model is ever run, and using slicing, cross-sections, streamlines and bubble maps to understand what the model is actually representing. Well and completion modeling follows, covering well trajectories, completion definition, well controls and the construction of development schedules.
History matching is treated as a structured process rather than trial and error, covering pressure and production matching, the parameters that are legitimate to adjust, fine-tuning strategies and how to judge when a match is acceptable. Uncertainty and sensitivity analysis is then used to bracket the range of outcomes rather than relying on a single deterministic answer.
The final section covers prediction and optimisation: building and comparing development strategies, waterflooding development cases including drainage analysis and streamline interpretation, well placement optimisation, and determining the best trajectory for a horizontal well. The workshop is delivered at an advanced level and is intended for reservoir engineers who build, review or use dynamic simulation models.
Workshop Objectives
By the end of this workshop, participants will be able to:
Describe the structure of a simulation input deck and the function of each data section
Prepare and quality-control fluid property and rock physics data for use in a dynamic model
Initialise a simulation model and calculate dynamic in-place volumes, and reconcile them with volumetric and material balance estimates
Review and quality-control 3D static grid models for geometry, property distribution and upscaling before dynamic use
Apply analysis tools including slicing, cross-sections, streamlines and bubble maps to interpret model behaviour
Create and edit 3D properties and manage multiple model cases
Define well trajectories, completions and well controls, and build development schedules
Carry out structured history matching of pressure and production data and assess the quality of the match
Define and run uncertainty and sensitivity analyses to bracket the range of possible outcomes
Apply fine-tuning strategies to adjust a model without invalidating the underlying geology

Excel in Production Engineering
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.
