STI provided geographic information (GIS) mapping support for Shell Exploration and Production Company (Shell). Shell was interested in visually displaying air emissions from its oil and gas production facilities and identifying the surface meteorological patterns in Southwest Wyoming. The map products included emissions density maps and site-specific wind roses for the months of February and March, 2004 through 2007, both day and night, in the Pinedale Anticline for Shell’s oil and gas production region.
