The present study has been conducted to evaluate the petrophysical properties of Sylhet Gas Field based on different logs data such as gamma-ray, spontaneous potential, density, neutron, resistivity, caliper and sonic logs. Quantitative properties including shale volume, porosity, permeability, fluid saturation, HC movability index and bulk volume of water were carried out using the well logs. Fourteen permeable zones were identified where six zones were found gas-bearing, one was oil bearing and the rest were water bearing. Computed petrophysical parameters across the reservoir provided average porosity as ranging from 16 to 26%, the permeability values range from 52 to 349 mili Darcy (mD) and the average hydrocarbon saturations are 75%, 68%, 77%, 76%, 63%, 73%, and 63% for reservoir Zone 1, Zone 2, Zone 3, Zone 4, Zone 5, Zone 6 and Zone 7 respectively. Hydrocarbon was found moveable in the reservoir since all the hydrocarbon movability index value was less than 0.70. An average bulk volume of water ranged from 0.04 to 0.08. Analyzed data indicate that the reservoirs are sandstone dominating with minor amount of shale and are at irreducible water saturation. The petrophysical parameters supported a hydrocarbon reservoir with good to very good quality which provide satisfactory hydrocarbon production.
