Abstract
This study investigates the hydrocarbon potential of the organic matter-rich Triassic rocks of the Newark basin in the USA. The development of anoxic conditions during the Late Triassic led to the accumulation and preservation of the organic matter during the deposition of the Lockatong formation in a lacustrine setting. The total organic carbon (TOC) values of the black shale samples from the Nursery and Titusville cores of this formation range from 0.50 to 2.72% (avg.=1.2%), indicating a fair to good source rock. On the Hydrogen Index (HI) vs the Oxygen Index (OI) diagram, the studied samples plot at the end of the evolutionary paths of kerogen types I, II, and III. This indicates that the organic matter is overmature and is in the dry gas window. This degree of maturity is also consistent with the Tmax values ranging from 506°C to 547°C and is confirmed by published vitrinite reflectance values (%Ro) which vary between 1.95 and 2.69%. This overmaturity is the result of an active subsidence during the Late Triassic-early Jurassic in relation with the reactivation with the deep-seated regional NE-SW-trending faults. Although the overmaturity of the organic matter renders the identification of the type of organic matter difficult, the organic matter is likely kerogen II-III type. On the basis of the available data, it is concluded that this formation has no generative liquid hydrocarbon potential.
