Seismic Stratigraphy
Consultant/Trainer: Maarten Wiemer/Mark Bouman
In this Petrogenium (in collaboration with EPTS) Seismic Stratigraphy participants in a seismic stratigraphy course gain advanced skills for hydrocarbon prospectivity evaluation, focusing on interpreting seismic data to understand sedimentary basin geology and predict reservoir, seal, and source rock distribution away from well control. They learn to integrate seismic, well log, and other geological data for improved subsurface predictions, which helps reduce exploration risk and increases the success rate of identifying hydrocarbon plays.
Participants
This Petrogenium course aims at Petroleum geologists and seismic interpreters involved with exploration and development of oil and gas fields.
Learning Objectives
At the end of this course participants will be able to recognize and map seismic facies belts, sediment distribution systems and litho-facies belts, and use this data for prospectivity assessment. The course spends at least 50% of the time on seismic interpretation exercises, based on data from a wide variety of geological settings. Lectures on theory and background alternate with exercises.
