Description
Summary:Petro-physical properties are the most important factor that controls the quality of the reservoir. Porosity, permeability, and the grain size are the main parameters to measure the quality of the reservoir. Thin section analysis was used to identify the arrangement of the grains within the rock. The existence of trace fossil can change the condition of the parameters of the reservoir. Bioturbation trace in a rock which made by organism activity, Planolites, changes the quality of reservoir significantly. The porosity value in a bioturbated zone was around 80 % and in the non-bioturbated zone wais 5 %. It increased the permeability too. This was identified from the interconnected pores in the bioturbated section, it has 90 % of quartz mineral with the same grain size relatively in bioturbated section and non-bioturbated section. The existence of Planolites trace implied that the outcrop was deposited in the deep-marine environment.
