BGS-AAPG Spring 2012 Field Trip
Facies and Applied Analog Significance of the Edwards Limestone and Eagle Ford Shale, Central Texas
April 14, 2012 from 8am to 4pm (lunch in the field)
Please email: Stacy_Atchley@baylor.edu
Stop 1: The Walnut-Comanche Peak-Edwards facies model based upon outcrops near Oglesby, Texas
Stop 2: Geochemical and depositional attributes of the Eagle Ford Shale (South Bosque Formation) near Woodway, Texas
Stop 3: Patch reefs and grainstone shoals within the Edwards Limestone near Crawford, Texas
Stop 4: Circular Edward's patch reefs along Childress Creek, northeast of Valley Mills, Texas
Stop 5: Facies variability within Edward's Limestone at Soldier's Bluff State Park, Lake Whitney, Texas
|Discussion Topics in the Field:|
1. The Edward's Limestone as an outcrop analog to subsurface counterparts.
2. The spatial distribution of rudist patch reefs and its implications on subsurface reservoir volumetric calculations.
3. Source rock geochemistry of the Eagle Ford Shale (South Bosque Formation) and a comparison to other noteworthy source rocks within North America.
