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.
Sample topic from the class:
“Mudrock Sedimentology in Unconventional Shale Reservoirs: Suspension Settling, Gravity Flow, or Current Transport”
This three-day core workshop will comprise classroom sessions, core viewing and core descriptions exercises. The workshop will focus on rock-based interpretation of mudrocks incorporating class room lectures and core examinations. Participants will learn how to apply mudrock depositional, sedimentological, and sequence stratigraphic principles and become gain an overview of geochemical, petrophysical, geomechanical and fracture classification principles to exploration areas and production assets in shale basins. Subsurface data from a variety of oil and gas shale plays will be examined. Day 3 will consist of viewing selected intervals of cores from the Bureau of Economic Geology (ie., Eagle Ford, Haynesville, Bossier, Barnett, Wolfcamp).
PLEASE NOTE: Day 3 is optional for customized in-house training.
- Characterize mudrock facies and identify facies and sequences in cores and be able to tie those to well-log character.
- Assess controls on source rock deposition, reservoir heterogeneities, and determine frackable intervals.
