Sequence Stratigraphy applied to carbonates and siliciclastics

This case study aims to integrate the different models of sequence stratigraphy in siliciclastic and carbonate depositional environments, with a specific focus on application cases. This course is especially designed to give attendees a detailled and hands-on method to practice daily sequence stratigraphic concepts. It will accelerate their understanding of the exploration process and enhance their autonomy for hydrocarbon prediction.

1. Document geologists and geophysicists with robust methods in sequence stratigraphy ranging from continental, shelf and basin environments. 
2. Lead attendees to gain in efficiency for interpretation in facies sequences, well logs and seismic stratigraphy.
3. Help attendees to be further predictive in play elements of any depositional systems. 
    

This course is a case study necessitating an active participation of attendees with hands-on practical exercises. 
All the results are reported during the week on a summary document A0 called "Sequence Stratigraphy Summary" which allows a general synthesis of the work, effective for a final presentation exercise.

The work is done on paper (seismic, well, graphs). All documents are provided.

No specific requirement for this course that can take place in any meeting room with validated HSE characteristics, in your company premises or elsewhere. 

Three effective days to one week (35-40 hours) is the ideal time. The case can be shortened or lengthened according to the request.
