Course Description
Business Impact: This course provides participants with the skills and knowledge to characterise fault-related fluid flow during all stages of the E&P cycle in structurally complex fields. Faults have the potential to act as significant seals in hydrocarbon reservoirs, withholding large fluid volumes over geological and production timescales. This course focuses on fundamental structural concepts that can be easily applied to most datasets, to generate an estimation of the seal capacity, and understand the risks associated with faulted reservoirs both in exploration and development settings.
This course builds upon understanding the basic concepts and application of fault seal analysis using worked examples through a series of classroom based lectures and exercises. Participants will be introduced to the fundamental concepts of structural geology and fault seal analysis, before learning in detail how simplistic methods can be employed to gain a comprehensive understanding of fault sealing behaviour and risk.
The Training Course Will Highlight ?
Training Objective
Target Audience
This training course is suitable to a wide range of professionals but will greatly benefit:
- Petrophysicists
- Geo-Modelers
- Geologists (Exploration and Development)
- Sedimentologists
- Seismic Interpreters
- Drilling Engineers
- Reservoir Engineers
- Technical Support Personnel
Training Methods
The course will not only be presented by showing and interpreting the material in detail, but also the participants will work together using real data to apply all the workflow and to project their previous knowledge and experience onto the course, they also encouraged to bring their own data so that real working examples can be reviewed and interpreted.
