The Meade and Kaolak test wells were drilled in 1950 and 1951 as part of the petroleum exploration program carried on by the U. S. Navy in Naval Petroleum Reserve No. 4, northern Alaska. The wells tested Cretaceous rocks on anticlines defined by seismograph surveys in the western part of the Arctic coastal plain, in areas hitherto little known geologically. Both were abandoned as dry holes, although Meade test well 1 produced a small amount of gas. Both tests penetrated beds of the Nanushuk group. In Meade test well 1 the Nanushuk group includes both marine and nonmarine sandstone and shale, and some coal. In Kaolak test well 1 the Nanushuk group consists of an almost completely nonmarine sequence which contains abundant coal. The sequence underlying the Nanushuk group in both wells is composed primarily of marine shale assigned to the Topagoruk formation in the Meade well and tentatively so correlated in the Kaolak well.This report contains. lithologic, paleontologic, logistic, and engineering information, obtained in drilling the tests; much of the data are presented graphically, j 164 148* PETROLEUM \''m-:-.RESERVE NO 41S t SOUTH BARROW TEST WELL t 2 SOUTH BAR ROW TEST WELL 2
The Titaluk and Knifeblade test wells were drilled in 1951 as a part of the exploration program of Naval Petroleum Reserve No. 4 in northern Alaska. Titaluk test well 1, which is 62 miles west of Umiat, was drilled to a depth of 4,020 feet. Knifeblade teat wells 1, 2, and 2A, which are about 68 miles westsouthwest of Umiat, were drilled to depths of 1,805, 373, and 1,805 feet, respectively. These wells were drilled on two different anticlines to test sandstone of the Grandstand formation of Cretaceous age (the principal oil and gas producing strata in the Umiat field, Alaska). Except for the few minor shows of gas and oil, the tests were dry.This report includes lithologic descriptions, paleontologic determinations, and engineering and logistic information obtained in the drilling of these tests. Some of the data are presented graphically.
