Sequence Stratigraphy and sedimentology GEO550

This course is designed to understand and interpret the depositional reservoir architectures of clastic and carbonate sedimentary depositional systems, the resultant stratal geometries and their evolution through time. The course aim is to give the student knowledge of depositional systems, within a chronostratigraphic sequence stratigraphic context, in order to understand and be able to predict the sedimentary elements (source rocks, reservoirs and seals) of the petroleum system. Knowledge of important stratigraphic trapping mechanisms associated with eustatic sea level lowstand conditions, proven by global analogues, will allow the student to identify and explore for previously unexplored unconventional trap types.

Learning outcome

Knowledge:

  • Relate sequence stratigraphy and sedimentary depositional response to  changes in base level cycles and basin architecture, 
  • Understand the changes in the basin response and reservoir deposition styles during the course of a single eustatic cycle,
  • Identify sequences and system tracts on seismic data and well logs for creating paleogeographic facies maps, in order to predict reservoir, source and seals,
  • Identify lowstand stratigraphic trapping mechanisms in different basins,
  • Understand post-depositional, deep burial-related, reservoir alteration processes.

Skills:

  • Use of sequence stratigraphic concepts for predicting all elements of the petroleum system,
  • Perform predictive sequence stratigraphic interpretations using various methodologies, relative sea-level changes, sequence boundaries, maximum flooding surfaces, systems tracts etc. in both clastic and carbonate systems,
  • Assemble chronostratigraphic charts to describe stratigraphic evolution, making use of concepts and techniques, which utilise marine/coastal onlap patterns and the recognition/prediction of reservoir and source rock depositional facies changes.

General competence:

Sequence stratigraphy is a predictive methodology, based on sedimentary response to changes in relative sea level, which gives the student an integrated approach to regional basin analysis, shelf to basin correlation and an understanding of reservoir heterogeneity. The framework of sequence stratigraphy allows the geoscientist to predict the presence of reservoir and source rocks, which have yet to be found, in unconventional stratigraphic trap types that have yet to be explored.
