Sedimentary facies and reservoir characteristics of limestone in Telong formation, Sungai Relai, Aring, Kelantan

Aring is located in Gua Musang, Kelantan. Aring consists of three formations that are Telong Formation, Koh Formation and Nilam Marble Formation. The age of the Telong Formation is Upper Permian-Upper Triassic. The Telong Formation in the study area consists of shale interbedded sandstone, claystone interbedded sandstone, shale interbedded sandstone and siltstone as well as limestone interbedded sandstone. The fossils that I found in the study area are Costaturia pahangensis, Neoschizodus ovatus and Anadonlophora sp. Castatoria pahangensis, Neoschizodus ovatus and Anadontophora sp. are classified as Phylum Mollusca which is bivalvia. The age of the fossils is Middle Triassic. The method of sampling is based on the facies. Facies analysis is carried out in order to determine the depositional environment. Three facies associations are found during the facies analysis that are facies association lower shoreface, facies association carbonate ramp and facies association intertidal flat. From the interpretation of facies, it is suggest that the deposition environment of the study area is shallow marine. To determine the reservoir characteristics of limestone, petrophysical analysis is carried out. The porosity and pore diameter of the limestones are identified.
