Who Should Attend

Petroleum geologists, geophysicists and reservoir engineers who are working in carbonates and need to understand facies heterogeneities and porosity distribution on exploration and production scales.

Objectives and Content

This seminar consists of a core workshop (1 day) combined with the examination of modern and Pleistocene deposits on Great Bahama Bank (5 days). This combination of subsurface data and modern and ancient deposits helps to illustrate the vertical and horizontal variability of facies and rock properties in carbonate platform reservoirs. Cores from a seven hole transect from Great Bahama Bank to the deep-water areas in the Straits of Florida (Bahamas Transect) provide a unique opportunity to assess the sequence stratigraphic distribution of facies and diagenetic modification in platform carbonate reservoirs. Log and laboratory data from these wells calibrate the rock properties and provide insights into porosity/velocity relationships and permeability in platform carbonates.

As modern analogs, the facies belts on Great Bahama Bank display the depositional heterogeneities that could occur in ancient hydrocarbon reservoirs. We explore the spatial heterogeneity within a carbonate platform, a facies belt or individual facies bodies, while simultaneously exploring the fundamental controlling processes. In particular, sedimentary structures, dimensions and lateral variability of classic reservoir facies are examined during the seminar. Pleistocene outcrops on Bahamian islands show how these facies are preserved in the ancient rock record. The goals of the seminar are (1) to illustrate the processes that produce heterogeneities in carbonates, (2) to improve the interpretation of subsurface data sets of carbonate systems and (3) to outline solutions for the construction of carbonate reservoir models.

Principle Objectives of Seismic and Core Workshop

  • To examine the facies, diagenesis and petrophysical properties of the seven transect holes that provide a ground truth for the seismic sequences of Great Bahama Bank for a comparison with existing sequence stratigraphic models
  • To relate facies and diagenesis to the rock properties and log and seismic signatures for a better understanding of the geophysical expression of reservoir facies in platform margins
  • To examine the porosity and permeability distribution along the Bahamas transect for an assessment of reservoir compartmentalization and fluid flow pathways from the source to the reservoir

Principle Objectives of Field Seminar

  • To observe the size, facies, and heterogeneities of the following modern carbonate environments, which are potential hydrocarbon reservoirs in the ancient: ooid shoals, platform interior facies, patch reefs, and tidal flats
  • To critically evaluate the concepts of cyclostratigraphy for reservoir characterization, using the modern depositional patterns as a starting point
  • To compare depositional and diagenetic aspects of the various modern environments with Pleistocene outcrops and subsurface examples
