The objective of this GLOMACS Stratigraphy training seminar is to get more out of seismic and well data through the use of sequence and seismic stratigraphy and integrated stratigraphic analysis to further constrain geological models. Ultimately, it can be used to predict and discover more hydrocarbon plays, to improve the estimation of play and prospect risk and to determine what lithology is going to be drilled ahead of the drill bit.

This 5-day interactive GLOMACS Stratigraphy training seminar will deal with the fundamentals and practical applications of sequence and seismic stratigraphy. It will include exercises and case histories for some interpretation and workshop discussion.

This GLOMACS training seminar will feature:

• The History of Sequence Stratigraphy
• The Models and Principles of Seismic and Sequence Stratigraphy
• Controls on Basin Stratigraphy
• Sequence Definition from Wells and Seismic
• The Fundamentals of Sequence Stratigraphy in Carbonate Systems
• Relative Sea Level Lowstands and Reservoir Development
• Sequence Stratigraphy in Lacustrine Environments
• Integration of other Stratigraphic Information, Biostratigraphical, Radiometric Dating, Chemostratigraphical

By the end of this GLOMACS training seminar, participants will be able to:

• Understand the critical use of chronostratigraphy in providing a temporal and spatial display of depositional packages
• Have a full understanding of sedimentary basin types and their depositional patterns
• Identify the main sequences on seismic
• Integrate other geological data and then identify sequences and parasequences on well logs
• Have awareness with the terms and definitions used in sequence and seismic stratigraphy
• Use sequence and seismic stratigraphy towards new play definition and as an aid in play and prospect risking

This GLOMACS Stratigraphy training seminar will be based around PowerPoint presentations for each module followed by interactive and participative individual and team exercises. There will also be workshop sessions based around real exploration and development case studies to get participants to actively become aware of the predictive capabilities of applied sequence and seismic stratigraphy and how to integrate other stratigraphical data. Seminar participants are also encouraged to bring along stratigraphic data, logs and seismic where appropriate from their own companies so that real working examples can be reviewed and interpreted.

An understanding of the concepts and the application of sequence and seismic stratigraphy in identifying clastic and carbonate hydrocarbon reservoirs and predicting their distribution is critical in optimizing exploration efforts for a company and obtaining the most from seismic and well data that has already been acquired at huge expense. For the organisation, the benefits will include:

• Getting the most out of expensively acquired seismic and well data
• Prediction of play trends for new acreage acquisition
• More accurate assessments of geological risk for prospects
• Identification of new plays and new leads and prospects
• Development of staff with new oil finding skills that can be applied to ongoing exploration projects immediately
• More accurate assessment of the prediction of reservoir presence and effectiveness in both clastic and carbonate plays
• More accurate estimations of Expected Monetary Value (EMV) for prospect economic assessments

Developing key interpretation skills in exploration play, lead and prospect generation provides a real personal benefit. The individual will enhance his predictive skills to become the proven oil finder that organisations are looking for. They will also become better at estimating geological risk which is key for accurate prospect portfolio generation. Personal impact includes:

• The ability to recognize and integrate sequences identified both from well log and seismic data
• Identification of systems tracts, bounding stratal surfaces and key geometries in shelf to basin transects
• Upon understanding the above to be able to predict the presence and distribution of clastic and carbonate reservoirs and to identify new plays, leads and prospects
• Have improved skills in geological risk assessments
• Have improved oil finding skills and better company and professional recognition

This GLOMACS Stratigraphy training seminar is suitable for exploration and development geologists, seismic interpreters, sedimentologists, petrographers and other upstream subsurface professionals who are interested in optimally utilizing geological data as a predictive tool in sedimentary basins and for identifying hydrocarbon plays in active petroleum systems.
