CSL'S Field Seminars

The CSL - Center for Carbonate Research and Education offers field seminars to introduce geologists and geophysicists to the facies and lateral changes in the modern and ancient carbonates. The seminars to some of the classic field locations illustrate in a unique way the size, facies, and heterogeneities of the carbonate environments, which are potential hydrocarbon reservoirs. The observed facies relationships and stratigraphic successions are used to critically evaluate the concepts of cyclostratigraphy for reservoir characterization and to compare depositional and diagenetic aspects of the various environments with subsurface examples.

Drift Delta Maiella Mountains

July 2019

Goal: To illustrate the geometry and facies distribution in a carbonate drift delta with discussions on sedimentary processes

Rationale: The recognition of the coarse-grained bioclastic wedge of the Orfento Formation as a drift delta prompts the re-examination of sea-level controlled deposition in carbonates. Current control is likely more important than previously thought.

Vaca Muerta Field Seminar

2019 TBA or upon request

Goal: To demonstrate how the detailed outcrop analysis can be a guide for interpreting subsurface data and potentially help to solve questions for well placement and production.

Objectives:

  • Illustrate the facies of Vaca Muerta – Quintuco system along a proximal to distal transect and the lateral distribution and vertical variability of TOC in the basin.
  • Relate the facies and geometries to the seismic facies and correlate changes in lithology and the diagenesis to chemical and petrophysical signatures measured with logging tools.
  • Discuss the outcrop-subsurface correlation based on calibration of outcrop geometry and lithology logs to subsurface logs and synthetic seismic sections.

Facies Successions on Great Bahama Bank - Implications for Exploration and Reservoir Characterization

2019 TBA or upon request

This seminar explores the vertical and lateral facies successions and heterogeneities of Great Bahama Bank. The seismic and core workshop on day 1 illustrates the architecture of the prograding western margin of Great Bahama Bank. Cores across the platform margin provide a unique opportunity to examine the sequence stratigraphic distribution of facies and diagenetic modification in platform carbonate reservoirs. Log and laboratory data from these cores provide insights into porosity/velocity relationships and permeability distribution in platform carbonates.

As modern analogs, the facies belts on Great Bahama Bank display the depositional heterogeneities that may 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. Field stops include the leeward platform margin (Cat Cay Ooid Shoal), the platform interior, the tidal flats of Andros, the ooid shoals of Joulters Cay, patch reefs, and the Andros Island barrier reef. Pleistocene outcrops on Bahamian islands show how these facies are preserved in the ancient rock record.

Ooid Sands and Microbialites Along the Exumas Margin - Depositional Models, Stratigraphic Framework and Reservoirs

2019 TBA or upon request

The seminar will illustrate the relationships and dimensions in an ooid-dominated, high-energy platform margin as well as the relationship of stromatolites and associated facies. This windward margin is a complicated arrangement of sedimentary bodies that are produced by physical and biological processes and influenced by Pleistocene and Holocene islands. In particular, we will focus on various sub-environments with differing grain-composition and different environments of stromatolite occurrence with various growth forms. Pleistocene island outcrops will illustrate the influence of meteoric diagenesis and also serve as overview points for viewing the dimensions of the various environments, further illustrating the heterogeneity of the margin.
