A geochemical profile of Tunalik No. 1 well, National Petroleum Reserve in Alaska
Arthur C. Banet Jr.
1983, Open-File Report 83-627
Plotting recently released organic geochemical data against depth shows that the sedimentary section penetrated at the Tunalik No. 1 well is prone to generate gas. Treatment of fifteen geochemical parameters illustrates the organic quality, quantity, and thermal maturity of well cuttings and core samples. Major maturity indicators suggest that the...
