Organic Maturity and Hydrocarbon Potential of Liassic Coals from the Eastern Pontides, NE Turkey

Abstract

Organic matter content, type of organic material, and thermal maturity of Lias-aged coals of the Gumushane and Bayburt areas were investigated. The total organic carbon contents of coals in the Gumushane area range from 0.39–35.46 wt%, and in the Bayburt area range from 0.02–50.64 wt%. The Gumushane (except Güvercinlik field) and Bayburt areas coals have low hydrogen index values. The coal samples contain a mixture of Type II and Type III kerogens. Based on average Tmax values Liassic coals in the Gumushane and Bayburt (except Cerci field) areas are mature, and potential yields are low.
