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…

January Meeting: Wind-blown sands and how to recognize them in modern dunes, outcrops and subsurface – Dr. Christian Heine
Wind-blown sands and how to recognize them in modern dunes, outcrops and subsurface. In and around the 4-corners, we are blessed with an abundance of well preserved and exposed ancient dune deposits. Most of the spectacular outcrops in the Utah National Parks are ancient dune deposits. At Zion it’s the Navajo, at Arches it’s the Entrada, at Canyon De Chelle it’s the De Chelle Sandstone. The Canyon Lands area of Utah has the Page, Cedar Mesa, Wingate and White Rim…
