Abstract:
Formation evaluation is a phrase used to describe the process that determines the viability of a formation to produce oil and other petroleum products. The petroleum exploration process of
formation evaluation actually includes several component procedures. Using geological
assessments, exploratory drilling, coring, and other procedures, petroleum drilling companies
are able to assess the value of a bore hole for production. Special core analysis (SCAL) is one
of the main sources of data available to guide the reservoir engineer in assessing the economic
potential of a hydrocarbon accumulations . The laboratory measurements subjected to water
saturation and permeability limitation. In this paper gamma-ray, Neutron-density and Archie
equation were used in a well called Hamara E-8 to determine shale volume, porosity and water
saturation. Zones were picked and the properties used to determine the types of reservoir and
then pay zones . Porosity and water saturation results were correlated with the special core data and we obtained a match in Zone-AD.
