Course Description
This course addresses the need for a systematic approach for quickly screening interpretations, maps, prospects and potential resources or reserves, and identifying fundamental interpretation, mapping and estimating errors. The reverse application of methods and techniques as presented in our courses such as Applied Subsurface Geological Mapping and Advance Structural Geology is the core of this course. The most common errors found on subsurface interpretations and maps are illustrated with numerous examples from around the world. The course begins with a review of examples of interpretation and mapping errors that led to poorly located wells that were uneconomic or dry, as well as inaccurate reserves or resource estimates. Methods used to address the risk factors that can cause dry holes are reviewed. Specific QLTs that can be used to identify critical interpretation or mapping errors are covered in the remainder of the course. The course manual is our textbook Quick Look Techniques for Prospect Evaluation. (Currently in preparation is the second edition “Quick Look Techniques From Prospect Evaluation to Reserves Estimation, planned for release in the Spring, 2007.)
Learning Outcomes:
- Develop an understanding of how to evaluate a variety of subsurface maps (fault, structure, isochore)
- Understand the types of questions to ask when reviewing interpretations and/or maps
- Evaluate the three-dimensional viability of an interpretation or map
- Evaluate whether the resources or reserves attributed to a completed interpretation or map are under or over estimated
- Determine whether an interpreter has applied sound, industry accepted geoscience principles and methods to generate a map
Offered as a Public or In-house course.
Who should attend
Prospect generators, property and prospect evaluators, supervisors, managers, bankers, investors and anyone involved in preparing, reviewing, or evaluating subsurface interpretations, prospects, fields and reserves or resources.
