Abstract
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 section is thermally mature for oil from approximately 3,300 feet to 10,500 feet (1,006 to. 3,200 m). Kerogen types are predominantly herbaceous and humic and, consequently, yield mainly gas. Additional gas is generated from the thermal degradation of hydro- carbons buried beyond maturity.
