How to Make a Good Reservoir Model: It’s Not the Software, It’s the Design (G036)

Tutor(s)

Mark Bentley: TRACS International Consultancy and Langdale Geoscience.

Overview

How can you tell the difference between a ‘good’ reservoir model and a ‘bad’ one? This short, focused class is designed to draw out the common reasons for ‘good’ and ‘bad’ outcomes, under the premise that models add value only when they add clear value to business decisions. The theme throughout the event will be the overriding issue of model design and the five areas of common error: model purpose; selection of elements; use of determinism and probability; model scale; and uncertainty handling. Advice will be given on how to review models, what questions to ask the model builders, and how to determine whether the output from models can be relied upon and used to support decisions. The course will close with a set of questions to ask yourself and others, suitable for reference in peer reviews or assists.
