Kansas Geological Survey, Open-file Report 1997-15
KGS Open File Report 1997-15
The table included in this report represents a compilation of oil-gravity data in the Forest City basin in northeastern Kansas, southeastern Nebraska, and northwestern Missouri. Oil in the Forest City basin is mostly an Ordovician-type oil with a unique geochemical character (Longman and Palmer, 1987; Hatch and others, 1987; Newell and others, 1987; Hatch and Newell, in preparation). The unique geochemical characteristics of Ordovician-type oils are: a strong preference in odd-number normal alkanes from C11 to C19, low relative amounts of heavier normal alkanes, and relatively low amounts of steranes and hopanes including pristane and phytane (Martin and others, 1963; Reed and others, 1986). These oils have been attributed to the organic-walled microfossil Gloeocapsomorpha prisca (Reed and others, 1986; Fowler, 1992). Due to incomplete fill-up of structures and their location deep within the basin, the Ordovician-type oils in the Forest City basin were probably generated within the immediate drainage areas of the traps that hold them, and are not the product of long-distance migration (Jenden and others, 1988).
The source documents for subsea and subsurface production depths in the compilation of oil-gravity data (Table 1) are scout cards for producing wells, which are available at the Kansas Geological Survey. Oil gravities were also obtained from these cards and from other sources that are footnoted on the table. Information in the table is summarized in two figures showing the variation of oil gravity with subsea depth (Figure 1) and with the projected subsea depth of the Middle Ordovician Simpson Group at each oil field (Figure 2). In some localities the Ordovician-type oils have apparently leaked vertically upward into shallower reservoirs, such as into the Silurian-Devonian "Hunton" group along the axis of the basin, and even into Mississippian and Pennsylvanian pay zones at the complex of oil fields at Easton and McLouth on the eastern flank of the basin. The plotting of oil gravities according to the depth of the underlying Simpson Group is an attempt to plot the variations in oil-gravity vs. the approximate depth of their most-likely source rocks.
A general increase in oil gravity with increasing depth occurs within the Forest City basin (Figures 1, 2). The increase of oil gravity with depth appears more tightly constrained when plotted according to the depth of the Simpson Group (Figure 2). It is unclear whether the upward decrease in oil gravity is due to temperature of the locality where the oil was generated, effects of migration up through the stratigraphic column, or the physical conditions in the reservoir. Geochemistry may provide answers. Oil fields that are significantly off the oil gravity-depth trends in Figures 1 and 2 (e.g., Bosch, Mill Creek Southwest, and Alta Vista East fields) may contain geochemically separate types of oil.

Table 1—Oil gravities and production depths for oil field in the central part of the Forest City basin and adjacent areas. Depth to Simpson is estimated for each oil field. Data were compiled from scout cards available at the Kansas Geological Survey except where noted. Fields are arranged according to location from north to south in the basin.
