Concepts, Models, and Case Studies of Dolomitization – with Applications to Hydrocarbon Exploration and Development

Despite intensive research, the origin of dolomite remains subject to considerable controversy. This is partly because some of the chemical and hydrological conditions of dolomite formation are poorly understood. This short course will help to provide an overview of dolomite research and highlight its major advances and controversies in recent years. This will be done by revisiting specific case studies and implementing newly developed concepts and models. The course will be taking place Saturday April 5th thru Sunday April 6th, 2014, in Houston Texas. * For more information on this course: Concepts, Models, and Case Studies of Dolomitization – with Applications to Hydrocarbon Exploration and Development

Who Should Attend

Petroleum geologists who work in any type of carbonate hydrocarbon reservoir, especially those in working in dolomitized reservoirs.

Attendees in this course will gain an understanding of:

  1. what creates dolomite in various geologic settings;
  2. the sizes and shapes that dolomitized reservoir bodies can attain;
  3. how and how much porosity and permeability can change via dolomitization.

Course Content

This course summarizes the major advances and current controversies in dolomite research. A major part of this course deals with the various dolomitization models, from early to late and from shallow to deep, from hypersaline reflux to hydrothermal dolomitization and MVT mineralization. These concepts will be applied to hydrocarbon exploration and development, with specific reference to the Devonian of Western Canada. Material will be presented through a combination of lectures, case studies and class exercises.

Topics will include:

  • Geochemical Constraints on Dolomitization
  • Textures
  • Petrophysics (porosity, permeability, capillary pressure, wire line logs)
  • Natural Environments and Models
    • Microbial-organogenic
    • Mixing zone
    • Reflux
    • Seawater dolomitization
    • Burial models
    • Fracture/Hydrothermal model
    • Dolomite, shales and mud rocks
  • Geochemical methods (trace elements, isotopes, fluid inclusions)
  • Case Studies
    • Permian Basin
    • West Carney Hunton
    • Smackover
    • Grosmont
    • Devonian
    • Albion-Scipio
    • Clarke Lake
