ONLINE LIVE STREAMING COURSE
5 Sessions in real time (approx 4 hrs/session): May 8th to 12th , 2023
WHO SHOULD ATTEND: Geologists, geophysicists and reservoir engineers who want to learn how to analyse traps and seals for oil and gas exploration.
This workshop presents the concepts and theories of trap and seal analysis from a pragmatic explorer’s point of view. Both top- and fault-seals are discussed. The effect of seal quality on gas-oil mix in trapped HC accumulations will be illustrated with examples from different petroleum provinces, and participants will be provided access to a computer tool (Ariane) to model how oil-gas mix is impacted by seal capacity for traps/prospects in their own prospects. All concepts are illustrated with examples and exercises from different basin types and settings.
- You will learn how to identify prospects with their spill and potential leak-points.
- You will learn the main theoretical aspects of subsurface sealing for permeability and hydraulic seals.
- You will be able to calculate Shale Gouge ratio and Clay Smear Potential.
- You will be able to make fault juxtaposition diagrams (Allen diagrams).
- You will be able to carry out geological mapping for such purposes.
- You will learn how to treat trap and seal risk and uncertainty in a realistic manner in probabilistic risk and volume assessments
- Identification of traps and their spill- and leak-points
- Unusual traps such as stratigraphic traps, hydrodynamic traps, basement traps, HCs trapped by tar
- Sealing lithologies and seal theory
- Top and fault seals, including SGR and CSP assessment
- Traps with multiple reservoir-seal pairs
- Characteristics of faults to assist fault mapping
- Differential retention for oil and gas
- Impact of seal quality on gas-oil mix, including access to a computer tool to model this
- How to deal with traps and seals in probabilistic Risk and Volume assessment of undrilled prospects
