A study of the Heath (Mississippian) and lower Tyler (Pennsylvanian) sediments of central Montana suggests a close relationship between the oil accumulations and the relative positions of the Heath limestone and the lower Tyler sandstones. Reconstruction of the pre-Amsden structure and the Tyler-Heath paleogeology shows that the oil accumulations at Sumatra, Stensvad, Ivanhoe, Keg Coulee, Bascom, Melstone, and Big Wall Fields occur where the paleostructural position of the lower Tyler sandstones is updip from, and in direct contact with, the Heath limestone. The foregoing relationships seem to be further supported by a study of Alice and Porcupine domes. These domes have barren sandstone reservoirs in excellent structural- stratigraphic traps. The peleostructural attitude in the area of the domes was flat and the Heath limestone apparently not well developed.
