Acknowledgments

I thank the U.S. Geological Survey (USGS) Southwestern Wyoming Province Assessment Team for the comprehensive geologic analysis that went into assessing undiscovered oil and gas resources of this area. I relied on geologic information provided in U.S. Geological Survey Southwestern Wyoming Province Assessment Team, 2005 to analyze oil and gas exploration and production activity. I also thank Robert Meyer, Wyoming Oil and Gas Conservation Commission (WOGCC), for performing database retrievals that were needed over and above what is available by default at the WOGCC website. Steve Casenave (ATA contractor for the USGS) assisted by assembling the video clip of historical drilling activity, and I thank him for his technical skills. Thanks also go to Greg Gunther (USGS) for managing the Energy Resources Science Center map serving hardware and software that allows us to publish interactive internet GIS services. Also appreciated is Greg's development of the Energy Resources Science Center WLCI website and the map viewer for ArcGIS Server (ESRI, 2008b). This manuscript benefited from the thoughtful reviews of Tom Finn (USGS) and Robert Waltermire (USGS); their efforts in this regard are much appreciated. Lisa Binder (USGS) is gratefully acknowledged for editorial review, and Tracy Pinto and Loretta Ulibarri (USGS) for final document design.
