October 25,. 1985 Reservoir/Petrographic Geology / Services Michael Minder Alaska Oil and Gas Conservation Commission 3001 Porcupine Drive Anchorage, Alaska 99501-3192 Dear Mr. Minder, Enclosed are four scanning electron microscopy photomicrographs of one sample from the Toolik Federal No. 2 well (5530-5600 feet) and one sample from the Toolik Federal No. 3 Well (2850-3300 feet), as well as labeled X-ray diffraction peaks for the seven samples analysed by XRD. Most of the samples originally borrowed from the library were not analyzed because of their paucity of magnetic material. Again, thank you for the use of the library; we hope that this study will be a significant contribution. If you have any .further questions, please feel free to contact me. 'Sincerely, CORE LABORATORIES, INC. Susan P. Grief Petrologist REC' VED · ,,,~: N,u 0 5 . Alaska Oil & Gas Cons· ConJ,-ntss~,,,, Anchorage Toolik Federal No. :2 Well Depth: 5530-5600 Feet Plate lA An anhedral grain of magnetite (F8) is shown here. This sample is probably detrital in origin. Plate 1 B This photomicrograph .displays a moderately crystalline, cubic magnetite crystal (E-F5). The euhedrai crystal morphology suggests that the magnetite may be authigenic. 6 ¸ 7 8 g 10 11 12 13 A I 2 3 4 ~; 6 7 8 9 10' 11 12 13 G B ,g 5 6 7 8 9 'tO 11 12 13 CORE LABORATORIES, INC.

The grain at E7 is likely detrital, while that at D-E7.5 may be authigenic. Plate 2 B This photomicrograph shows a magnified view of an anhedral ulvospinel grain (E7). The grain is probably detrital. 5 6 7 8 9 10 ~ 12 15 ~ 6 7 8 9 10 11 12 13 A 5 6 7 8 9 ~0 11 12 13 B CORE lABORATORIES, INC.
