Evaluating the Hydrocarbon Sealing Potential of Faults and Caprocks

Review Abstracts


This Hedberg conference brought together workers from various disciplines (geology, geophysics, engineering, petrophysics) to discuss state-of-the-art concepts, methodologies and case histories relating to top, intraformational and fault seals.


  • Petrophysical Characterization of Seals
  • Sedimentology/Sequence Stratigraphy of Seal Rocks
  • Seismic Characterization of Top and Fault Seals
  • Seals, Migration and Fluid Flow
  • Regional Stress/Geomechanics
  • Faults: Sealing or Non-sealing?
  • Reservoir Compartmentalization: Seals, Baffles or Barriers?
  • Reservoir Simulation with Internal Seals
  • Paleo Columns and Seals

Specific discussions focused on:

  • Determining characteristics of fault zone seals;
  • Evaluation of stratigraphic (capillary) traps/lateral seals;
  • Geochemical characteristics of seal lithologies;
  • Wireline log evaluation of seals and internal reservoir baffles;
  • Petrophysical/petrographic properties of seals;
  • Seismic detection of seals;
  • Effect of seal geometries (thickness, lateral extent) on seal potential;
  • "Engineering" aspects of seals; Case histories of expected vs. actual seal capacity;
  • Examples of multi-institutional, multi-disciplinary studies of the issues of top, intra-formational and fault seal integrity within key basin systems are especially welcome.
