And if in some of such districts, like the Urals and Pennsylvania, petroleum is met, its distribution in the vertical direction is traced much lower than the layers rich in organic substances, and, consequently, must have another source. THE VERTICAL RANGE OF HYDROCARBON MIGRATION The vertical distribution of petroleum and gas also indicates a much wider range of hydrocarbon migration than accepted in different variations of the. Fig. I. An example of the connections between oil deposits and dislocations of the basement and sedimentary cover of the tectonic platform: oil field of El Dorado, Kansas, Vertical section: the vertical scale is considerably more than the horizontal (cited by Moore from Ver Viebe, 1950). 1—drill holes; 2—Pennsylvanian rocks (C3); 3—Mississippian sediments (limestone Ci); 4—Ordovician sediments (S); 5—granites of the pre-Cambrian crystalUne basement; 6—Stapleton oil zone in the lower Palaeozoic rocks. organic theory. The secondary nature of oil pools usually does not raise any doubt. I. O. Brod pointed out that 'if we are to understand as primary deposits those which originated in situ, then we must state that such deposits do not exist at air [18]. Obvious structural geological and hthological evidence is always found to show that these hydrocarbons came to the reservoir rocks not only after the formation of the rocks bearing them, but after the rocks have undergone the action of tectonic forces (fractured, flexed and folded).
