This course covers the concepts, methods and applications of modern stratigraphy, with respect to reservoir characterisation, facies model and applied sequence stratigraphy. It will particularly emphasise the integration of different disciplines in order to characterise the sedimentary basins and to reduce the uncertainties. The course is designed to describe and analyse both clastic and carbonate reservoirs, their internal facies architectures, using also case histories and exercises from field analogues. Well-log data and core example, well correlation and applied seismic stratigraphy will support the learning.
A geologist, geophysicist or reservoir engineer, keen to understand the methodology for applying sequence stratigraphy to correlation, facies analysis and delineation of stratigraphic traps
How we build your confidence
Overview of study principles and methodology
Discussions of recent developments and significant applications
Case histories that demonstrate the applications and efficacy of stratigraphic and related techniques
Application of sequence stratigraphy to carbonate and clastic settings, based on the description of outcrops and core logs that can be used to predict source rock, reservoir and seal distributions within a basin
Consideration of the diagenetic processes that affect carbonate and clastic sediments and how the integration of diagenesis and sequence stratigraphy can provide a better way of predicting reservoir quality
The benefits from attending
By the end of the course you will feel confident in your understanding of:
The concepts and practical applications of sequence stratigraphy for petroleum exploration
How to recognise facies assemblages from outcrops and core data and to reconstruct facies architecture
The limitations of litho-correlation and the benefits of chrono-correlation and integrated stratigraphic methods
Relative sea-level changes and their effect on the distribution of source, reservoirs and seal rocks
