Abstract
The study areas have five locations consisting of Amphoe Lom Sak (ALS), Amphoe Nam Nao (ANN), Grand Canyon Nam Nao (GCNN), Amphoe Mueang Loei (AML) and Amphoe Pak Chom (APC). This study focuses on Huai Hin Lat Formation, Wang Saphung Formation and Nong Dok Bua Formation. Lithology in the study areas consists of calcareous mudstone, argillaceous mudstone, coal-shale, calcilutite, calcarenite and argillaceous shale. A total of eighteen samples for geochemical analysis included quantity, quality, and maturity are useful for identifying and interpreting petroleum source rock and depositional environment. The Total Organic Carbon (TOC) ranges from 0.03 - 20.17 wt.% which is poor to excellent capacity for petroleum potential. Extractable Organic Matter (EOM) ranges are 60 - 4127 ppm (poor-excellent). Type of kerogen is type III (gas prone) and someplace found in type-IV (inert/dry gas) since the components value of Oxygen Index (OI) is higher than Hydrogen Index (HI). Maturity levels of the rock samples in the study area are in immature to over mature stages. The stratigraphic section shows the depositional environment in Amphoe Nam Nao (ANN) and Grand Canyon Nam Nao (GCNN) part of Huai Hin Lat Formation is lacustrine-floodplain or levees and the Amphue Mueang Loei (AML) part of Wang Saphung Formation deposited in foreslope-backreef or lagoon.
