BELL Urbana, Illinois ABSTRACT During the 4 years, 1944 to 1947, sixteen oil test wells were drilled in Illinois to the St. Peter sandstone, of which thirteen penetrated to various formations below the St. Peter, two reaching the basement rocks. Isopach maps of various formations between the St. Peter sandstone and the basement rocks, supplemented with cross sections, show the influence of the Ozark and Wisconsin positive structural areas. Notable variations in the stratigraphic sequence are the disappearance of the Galesville sand- stone and the introduction of an oolitic limestone in the Cambrian strata in central Illinois. Maps show the structure of the Illinois basin on the top of the St. Peter sandstone and the general configuration of the basement surface so far as known. Isocons on the St. Peter map show the total mineral content of water in the St. Peter sandstone. Some of the geological factors that should be considered in prospecting for oil in these deep strata are discussed. The geological situation with regard to the possibilities of obtaining oil by deeper drilling in Illinois was reviewed by the Illinois Geological Survey in an article published in the early part of 1044. 3 Since that time 16 wells have been drilled in Illinois to test for oil in the St. Peter or deeper formations. Thirteen of these wells tested below the St. Peter and two reached the basement rocks. These tests were at scattered locations along the west side of Illinois from Madi- son to Hancock counties and in central to northern Illinois from Douglas to Lee counties. No oil was obtained but it may be of value to summarize for the benefit of further prospecting the geologic information now available. Figure 1 shows the locations of two geologic cross sections, AB and CD 7 drawn through 15 wells. One extends north-northwestward from St. Louis to southern Hancock County, thence northeastward to northeastern DeKalb County. The other extends northeastward from southwestern Jersey County to Kankakee County, excepting that well 12 is a little more than 40 miles south- east of the general line of section. The top of the Glenwood-St. Peter sandstones is the datum from which the succession of strata are shown to extend downward in the cross sections. MT. SIMON-FOND DU LAC (?) SANDSTONES The Fond du Lac (?) is an incoherent sandstone at the base of the sedimentary series in Illinois. It consists of very fine- to very coarse-grained, pink, yellow, and white sand grains that are somewhat rounded. The Fond du Lac (?) constitutes most of the Mt. Simon-Fond du Lac (?) succession, and is very difficult to sepa- 1 Read at the Eastern Interior regional meeting at St. Louis, January 15, 1948.

Simon, which is white and somewhat finer in texture. There are here and there thin beds of red, greenish gray, and dark gray shale in the Fond du Lac (?). In the wells of northern Illinois that reach or ap- proach the basement granite, 70-440 feet of arkosic sandstone is present in the basal Fond du Lac (?). The Lamotte sandstone of Missouri is equivalent to one or both of these sandstones, and the name Lamotte is commonly applied to the basal sand in near-by Illinois.
