May Talk: Seeing the Forest for the Trees Across North America’s Cordilleran Foreland Megasequence by Erik Hulm, TeoGeo Consulting
Seeing the Forest for the Trees Across North America’s Cordilleran Foreland Megasequence by Mr. Erik Hulm, TeoGeo Consulting ABSTRACT: The North American Cordilleran foreland basin once formed a contiguous succession of sedimentary rocks that extended from the Gulf of Mexico to the Arctic Ocean. Much has been published on the structural character and evolution of the Cordilleran but little on the full breadth of the foreland sedimentary fill and hydrocarbon endowment. This is largely due to post-Cretaceous structural modification and…

October Meeting: An Eocene “Source-to-Sink” Example in Piggyback Basins, Pyrenean Fold and Thrust Belt, Spain – Jeff Geslin, PhD (Pictured Cliffs Geoscience LLC)
An Eocene "Source-to-Sink" Example in Piggyback Basins, Pyrenean Fold and Thrust Belt, Spain Abstract" A well-exposed example of a source-to-sink depositional system was evaluated using Middle Eocene (Lutetian) strata contained in piggyback basins of the Pyrenean Fold and Thrust Belt (PFTB). The purpose of this study was to: 1) refine sequence stratigraphic models linking continental, shelf and deepwater settings; 2) understand external controls on sediment flux; 3) evaluate the effect of multiple sediment entry points in a basin; and 4)…

December Meeting: Unconventional petroleum systems in the Western US – Dr. Ron Hill (EOG Chief Geoscientist)
Main talk - Ron Hill Abstract: The Unconventional Bakken Petroleum System: What Geochemistry Indicates about Petroleum System Processes The Bakken Formation has been the target of intense petroleum exploration activity over the last fifteen years, and is widely considered an unconventional resource or a ‘tight oil play’. The ‘tight oil play’ designation has evolved in part because the Bakken Formation, a world class source rock, is the drilling target. However, the primary reservoir objective within the Bakken formation is not…
