Production - Domestic - Oil and Gas Development in Illinois in 1936

The year 1936 in Illinois was marked by considerably increased activity in drilling, both wildcat and proved territory, in leasing, and in seismic and geologic exploration. Of the 92 oil and gas wells completed during 1936 in Illinois, 49 were oil wells, 3 were gas wells and 40 were dry holes. This compares with but 34 completions in 1935. The total of the daily initial productions of the new oil wells was 1755 bbl., or an average of 36 bbl. per well. One new field was discovered, the Bartelso field in Clinton County. The leasing of some large blocks of acreage in Clay, Marion, and other counties by the Carter Oil Co. in the late fall of 1935 was followed in 1936 by extensive leasing in southern Illinois by 10 major companies and many smaller companies and individuals. It is estimated that 2½ million acres were under lease by the end of 1936. Seismograph surveying has been carried on by about seven companies, and the number of seismograph parties operating in Illinois has varied from six to eight throughout most of 1936. It is estimated that approximately two million dollars has been spent in the state in seismic and geologic exploration and in leasing during the last quarter of 1935 and all of 1936. Production of crude oil in Illinois in 1936, according to the Bureau of Mines, was as follows: Barrels Barrels January...................... 325,000 July........................ 402,000 February..................... 294,000 August..................... 380,000 March....................... 396,000 September.................. 386,000 April......................... 347,000 October.................... 393,000 May......................... 389,000 November.................. 363,000 June......................... 383,000 December................... 387,000 4,445,000 This 4,445,000 bbl. was an increase of 3 per cent over 1935. Although this increase was due largely to the fact that production was not artificially curtailed, it also reflects some new production and some increases in production from repressuring and water-flooding, which offset the
