WHO SHOULD ATTEND

The material should be of interest to exploration and development geologists, reservoir geologists, reservoir engineers, petrophysicists, log analysts, geophysicists and managers of all these disciplines.

COURSE OBJECTIVES

The workshop provides attendees with knowledge and a thorough coverage of the basic and advanced principles, practices and applications of Clastic Sequence Stratigraphy. The lectures and practical covered in this course should help earth scientists of all branches develop more sound models for the stratigraphic correlation, prediction of the presence, architecture, continuity and trend of the reservoir, establish basics for reservoir modeling and help managers make educated decisions when faced with proposals from their development and exploration geologists concerning such reservoir aspects. Similar knowledge is gained concerning source and seal rocks through principles discussed in the class. By the conclusion of the course it is expected that all participants should:

At least have acquired working knowledge of basic principles and practices of clastic sequence stratigraphy
With individual wireline logs, and with help from sedimentological core descriptions, recognize facies tracts, Para sequences and their stacking patterns
Correlate stratigraphic cross sections based on sound sequence stratigraphic practice. This in addition to utilizing sedimentological core descriptions, you should be able to recognize sequence boundaries, flooding surfaces and the various systems tracts. When correlating these entities from well to well a clear logical picture should emerge concerning the depositional history of the area concerned
Be able to breakdown a complex stratigraphy into its genetically packaged units. The sequences
Map the spatial distribution of the genetic units and understand their temporal succession
Predict distribution of source, seal and reservoir rocks from above maps
Understand the architecture and plumbing of the reservoir rocks from following sound concepts of sequence stratigraphy
