Termus shale of central Pahang, Malaysia: kerogen typing by palynofacies analysis

Palynofacies study has been done on selected samples fom the Late Jurassic - Early Cretaceous Termus Shale from Kuala Tahan, Jerantut-Jengka and Maran in Central Pahang to study its kerogen properties. Palynofacies study reveals distinct organic matter composition of different biological affinities from the samples where the organic matter composition were sorted into maceral groups and then by its distribution, to standard kerogen types. Three types of kerogens were interpreted: kerogen Type I, kerogen Type III and kerogen Type IV. Kerogen Type I and Type IV is interpreted in Kuala Tahan, Type III in Jerantut and kerogen Type III and Type IV are interpreted in the Maran area. The overall kerogen types correspond to different hydrocarbon potential ranging from high-low oil and gas potential. © Published under licence by IOP Publishing Ltd.
