Woodbine Formation, East Texas Basin

Comments on Geologic Parameters

7 Top Seal Thickness:

The Eagle Ford shale is the low-permeability unit immediately on top of the Woodbine. A thickness map was digitized from Surles (1986) and gridded (c7woodbineg). More regional-scale stratigraphic and facies information is available from this source. The Eagle Ford has been eroded over the Sabine Uplift in the eastern part of the study area; however, the low-transmissivity Austin Chalk extends over this area.
