Who Hexed Hoodoo Hills?
A Case History of a Subthrust Mountain-front Test, Wind River Basin, Wyoming Charles A. Hinson El Paso Production, Houston, Texas Hoodoo Hills was an 18,600 test of a large structural prospect located beneath the Owl Creek Thrust, which forms the northern structural boundary of the Wind River Basin located in central Wyoming. The Hoodoo Hills structure is analogous to Madden Field, a structural culmination located six miles east of Hoodoo Hills. Both features are comprised of large folds formed by rollover into deep seated thrust faults. Prospective reservoirs were the tight gas sands of the Upper Cretaceous section, particularly the Shannon sands, which have produced over 250 BCF in Madden Field. The prospect concept was based on the idea of testing the Shannon Formation in a more structurally favorable location than the Moncrief Lysite Unit 12-1. The 12-1 well was drilled on the flank of the Hoodoo Hills structure, several thousand feet down dip from the Hoodoo Hills location, and it
