This introductory course is designed for early career geoscientists, technical assistants and petroleum engineers who wish to build a strong understanding of the fundamental elements of petroleum geology. It provides hands-on experience of typical oil industry data types and workflows for exploration and production, taught by a very experienced petroleum geoscientist.
The course starts by placing hydrocarbons in a global context; the philosophy and structure of the oil industry; energy trends, future resources. The petroleum environment is then reviewed: source rocks, reservoirs, traps, seals and the timing of generation relative to trap formation. The course then examines the subsurface environments, subsurface temperature and pressure and the impact on petroleum systems, the usage and display of typical subsurface geological data, and gives an introduction to seismic and wireline logs. This is then developed into a definition of petroleum systems and an introduction to play fairway definition and finally leads / prospects. The course concludes by introducing the assessment of subsurface resources by calculating in-place reserves using deterministic methods.
Course Level: Foundation Instructor: Jonathan Redfern
Designed for you, if you are...
A new hire graduate geologist, geophysicist or an engineer with limited experience of hydrocarbon exploration
Some basic geological knowledge is assumed, but no prior experience of oilfield data or techniques used to interpret these datasets.
How we build your confidence
The course will help you build a solid understanding of the elements of the petroleum systems, and introduce key data types and methods of analysis. You will understand key language used, worflows and the extensive practicals give you introductory experience of using and interpreting typical oilfield data. Examples are taken from global petroleum systems, drawing on the experience of the tutor.
