Petroleum Geology of Henry Mountains Basin

C. D. Irwin, W. R. Clark, W. W. Peabody


The Henry Mountains basin is one of the few currently non-productive basins in the Rocky Mountain area.

Oil shows are common in Triassic and Permian beds and several large tar-sand deposits are present along the basin margins. The source of much of the oil is probably the Triassic Woodside Shale.

A few obvious structural features that could trap oil have been drilled. Deep canyons cut by the Colorado and San Juan rivers and their tributaries have lowered reservoir pressures around much of the basin perimeter. If commercial production does exist, it will be found in stratigraphic traps and inconspicuous structural traps formed prior to the Laramide orogeny.
