A general examination of the stratigraphy of the South Pyramid Hills oil field demonstrates that oil occurs at depths varying from 1,100 to 3,200 feet, in beds of middle Miocene and upper Eocene age.
A detailed analysis of the stratigraphic and structural relationship indicates that the accumulation is effected by anticlinal folding in conjunction with faulting and unconformable overlap. These latter features, although responsible for the presence of the several producing zones, present difficult problems affecting the economic development of the field.
