Cover Story: Although the photoelectric Factor (PEF) log is a powerful tool for distinguishing between siliciclastic and carbonate lithofacies in well-log analysis and 2D correlations, its application in complex reservoirs faces some challenges due to well spacing. We present a workflow to extend its capabilities into a 3D space to identify the productive zones within the Pennsylvanian Strawn and Canyon reef complex in the Salt Creek field, West Texas. The most productive zones are the oolitic grainstones and the skeletal packstones, but they are difficult to identify. Because these zones on the PEF log are characterized by values ranging from 4.26‒4.78 B/E, we used a machine learning procedure involving testing and validation processes to generate a PEF volume that facilitated their identification in a 3D sense. View this paper

We propose the hypothesis that dune gullies and seasonal “meteorological” appearances observed on the same dunes (e.g., frosting) may have a common origin. These gullies are difficult to explain through the action of liquid flow. The occu...
