Spread Creek anticline is a large, doubly-plunging, closed anticlinal structure in northeast Teton County, Wyoming. The area of closure is approximately 20 mi long and 2 mi wide. Closure based on surface geoloyy may exceed 2000 ft. No commercial guantities of hydrocarbons have been established by exploratory drilling. Eleven deep exploratory tests and four shallow core holes have been drilled on or adjacent to the fold, one of which reached strata of Cambrian age. The axis of the fold migrate to the northeast with depth. For part of the fold, there may be no dip reversal and therefore no closure at the level of the Permian Phosphoria Formation and the Pennsylvanian Tensleep Sandstone. Natural gas seeps are probably due to degassing of coal beds near the surface and do not reflect a deep trapped hydrocarbon accumulation.
