From the Introduction
Cores in the Woodbine Group in East Texas field display a variety of deltaic and fluvial facies. This workshop presents cores from fluvial-dominated deltaic deposits in the central and south parts of the field (Shell No. 55 Watson, ARCO No. 21-X Kinney, and ARCO No. C-19 Pinkston wells) and coarse-grained incised-valley-fill fluvial deposits in the north part of the field (ARCO No. B142 King and Cities Service No. B2 Killingsworth wells) (Fig. 1).

Cores are useful in understanding reservoir architecture because they display a vertical profile of rock fabric, contacts between beds, and sedimentary structures. Vertical trends in lithology, grain size, and stratification record changes in sedimentary processes and depositional environments through time. Workshop participants will observe numerous examples of vertically superimposed sedimentary facies from deltaic, fluvial, and transgressive-shelf depositional systems.
