American Association of Petroleum Geologists

Evaluation of Tight-Shale Reservoirs: Sedimentologic, Stratigraphic, and Geochemical Tools to Identify Production Sweet Spots

28 September - 1 October 2020
Virtual Event


Who Should Attend

Geoscientists, reservoir engineers, and managers who desire to develop a better understanding of the geological, mechanical, and chemical character of mudrock systems and how mudrock attributes vary in the context of shale gas/oil reservoir exploitation.


Participants will learn to:

  • Learn how stratigraphic, geochemical and depositional processes influence regional correlations and facies variations of organic-rich mudrocks with respect to calcareous, siliceous and clay-rich shales.
  • Judge controls on source-rock deposition, reservoir heterogeneities and determine frackable intervals.
  • Assess and interpret geochemical data critical to understanding mudrock systems.
  • Recognize and quantify the rock properties that will have an impact on completion success.
Course Content

Course will be held via Zoom: 28 September1 October 2020, 8:00 am11:00 am (CDT)

This virtual short course focuses on methods and workflows for identifying, characterizing, and developing tight-shale reservoirs. Participants will learn how to apply mudrock depositional, sedimentological, sequence stratigraphic, and geochemical principles to exploration areas and production assets in shale basins. Subsurface data from a variety of oil and gas shale plays will be examined and in-class exercises will contribute to understanding on controls of sweet spots.

The on-line class will utilize lectures and exercises, to address the reservoir characterization, sedimentology, facies, sequence stratigraphy, and geochemistry of shale-gas/oil bearing mudrocks.

Module 1

Approaches to understanding the geology of shale-gas/oil plays

  • Overview of organic-rich mudrock systems
    • Carbonate-dominated systems
    • Clastic-dominated systems
    • Mud-dominated systems
  • Factors determining organic-rich deposits
    • Paleogeography
    • Ocean chemistry
    • Climate
    • Modern examples (Cariaco Basin)
Module 2

Stratigraphic and depositional processes in shale basins:

  • Stratigraphic framework
    • Regional correlations and variations
    • Sequence stratigraphy (shelf to basin correlations)
    • Exercise

Interpretation of depositional environments in shale basins:

  • Facies interpretations
    • Calcareous shales (Haynesville, Eagle Ford example)
    • Siliceous shales (Barnett example)
    • Clay-rich shales (Neal Shale; Tertiary Shale)
  • Mudrock sedimentology
    • Sedimentary structures and depositional processes
  • Exercise
Module 3

Geochemical Tools and Geochemistry Review

  • Overview of definitions in source rock evaluation
  • Lithology: XRD and XRF
  • Organic-matter type and richness: Kerogen / TOC
  • Maturity: Rock-eval

Interpretation of Geochemical results – incorporating data

  • XRD and exercise
  • XRF and exercise
  • TOC and exercise
  • Rock-eval and exercise
Module 4

Inter- and intrabasinal variations – examples from different shale basins (Haynesville, Barnett, Eagle Ford, Marcellus, Bakken, Wolfcamp)

Integration Exercise: evaluating and finding best shale reservoirs using learned skills
