A STUDY ON OIL FIELD SANDSTONE THROUGH POROSITY AND PERMEABILITY PARAMETERS

Crude oil reservoirs have different formation types according to their environmental and geological conditions. Sandstone is one of the most common formations of crude oil reservoir, which has high oil bearing capacity than carbonate formation. In this research article, oil field sandstone was collected and analysed through porosity and permeability. The sandstone was visually observed for the classification of sandstone. The porosity of the sandstone was determined by porosimeter equipment and found to be 10.93 %. The permeability of sandstone was measured in the gas permeameter and found to be 0.084 mD. The core flooding operation gives an idea about the recovery efficiency of particular core and crude oil. The oil recovery efficiency of water flooding and chemical flooding was found to be 35 % and 42.23 %. The recovery of crude oil was slightly less in the water flooding mechanism due to the low porosity and permeability of sandstone. The determination of rock characterization in the initial stage helps in finding the better recovery technique, suitable for the oil production.
