Identifying pay zones in FRB-2 well using well log data

In order to determine the porosity, reservoir characteristics and pay zones within the reservoir intervals. Two different porosity logs were used, they are density and neutron logs. According to the porosity logs density and neutron logs, the FRB-2 well has significantly divided to three major intervals, that are acting as a good to very good porosity or reservoirs, because their porosity values are ranging from 15% to 20% at the depths of 7592ft to 7840ft, 7860ft to 7880ft and 8104ft to 8200ft. Additionally, the combination of density and neutron logs are also used to acquire the better result of porosity data and then identify the porous and pay zones in a certain depth of the well. Then, the resistivity log is also used in order to obtain more data about the selected depth. This log shows that the well contains hydrocarbons in the reservoir intervals, this is identified based on the resistivity data. The value of 240 Ωm of resistivity log records at the depth of 7598ft. The resistivity is continuing as a high value to the depth of about 7740ft. The second zone’s resistivity value is also high; the range is between 400Ωm: and the highest value records at the depth of 8320ft.
