An essential part of an ongoing seismic interpretation, whether 2D or 3D of a faulted reservoir is a structural analysis of the faults. Uncertainties in fault interpretation can be reduced, and a more robust reservoir model therefore built. Important issues of fault continuity, how and where faults join, the juxtaposition or separation of reservoir across faults, and the overall geometry of the reservoir can be addressed. Resolving these uncertanties is essential prior to building a full reservoir model, and has a direct bearing on key isues such as reservoir volumes and well planning. The process is relatively straightforward, and once learned, can be implemented into the overall project workflow. The value of incorporating such procedures is soon realised. The approach is practical, and will use the various software tools that ABAL have developed.

• Analysis of normal faults
• Displacement gradients
• Fault plane diagrams
• Fault relay zones
• Fault population analysis
• Applications of displacement analysis
• Overprinting of fault inversion movements on normal faults.

Length: 1 day (maybe 2 if more practical examples can be built in)
Outline: A practical introduction to structural geology and the techniques for validating a fault interpretation. The course will be based around class based teaching and practical hands on exercises including use of ABAL's software.
Benefits: This course will teach you practical methods of validating a fault interpretation, how to spot errors and uncertainties and how they may be resolved.
Requirements: Access to suitable PC's for the practical part of the course.

2. Fault seal and reservoir characterisation

This course follows on logically from the above, and knowledge of fault analysis techniques is important. In this course we address issues of fault seal and reservoir compartmentalisation, and the way that risks to drilling, reservoir volumes and reservoir production may be tackled in terms of structural geology.

Topics include:

• Reservoir scale structural geology
• Factors contributing to fault seal
• Determining fault seal using fault seal algorithms
• Applications of fault seal analysis
• Assessing compartmentalisation and migration.

Length: 2 days
Outline: A practical introduction to structural features which can affect reservoir quality and permeability. Fault seal algorithms and methodologies are described in detail and demonstrated in practical exercises using ABAL's software. This course gives an introduction to the techniques available and the choice of the most appropriate methodologies to address fault seal uncertainty. This course is best run after the "General structural QA: Fault analysis" course with participants learning the broadest range of practical techniques.
Benefits: From this course you will learn what fault seal techniques are, how to apply fault seal techniques to solve practical problems relating to hydrocarbon migration and accumulation, and dynamic production including the importance of compartmentalisation.
Requirements: Access to suitable PC's for the practical part of the course.
