In this study, AVO/AVA Synthetics and petrophysical well log analysis was carried out to discriminate between the reservoir and non-productive lithology for two wells Naimat Basal 01 & Siraj South-01. Synthetic AVO/AVA traces of Naimat Basal 01 & Siraj South-01 were generated. The behavior of the theoretical and NMO corrected synthetics for Naimat Basal 01 has a weak response, while Siraj South-01 indicated a clear sharp anomaly. AVA synthetic created for well Naimat Basal-01 and Siraj South-01 using Zoeppritz equation clearly indicated amplitude variations. On the basis of AVO/AVA anomalies petrophysical well log analysis was carried out for Naimat Basal-01 from 2600-3550 m depth. The two zones interval 3395m- 3411m and 3480m-3497m were studies in detail which confirmed the results obtained from AVO/AVA synthetics and 3395-3411m and 3480-3497m may be good reservoir zone for the hydrocarbon accumulation.
