This training will provide the necessary technical know-how for the geoscientist to feel comfortable with the utilization and the integration of this data into their everyday workflows. This will aid their efforts in both the exploration for new hydrocarbons and in the development of existing fields. Participants will learn different biostratigraphical techniques, how to plan and optimize a biostratigraphical program, how to use biostratigraphical data in well to well correlations and in seismic interpretation. Also, participants will learn how to identify the pitfalls in the use of biostratigraphical data and therefore to optimize its use in sediments of different ages and in different paleoenvironments. Practical applications for the business will be the focus of the course, using biostratigraphical data to support exploration efforts, as well as for facies interpretations and reservoir correlations in appraisal and development situations.
