Abstract :
Identification of key sequence stratigraphic surfaces is an essential task in geological evaluation of hydrocarbon reservoirs. The Sarvak Formation with Late Albian-Early Turonian age constitute the important reservoir unit in the Abadan Plain region, SW Iran. This study investigates the application of Normalized Cumulative Gamma Deviation Log (NCGDC) to discriminate and correlate key sequence stratigraphic surfaces in six wells in a giant oil field in the Abadan Plain. To achieve this goal, identified key stratigraphic surfaces from core and thin sections were compared with interpretation of NCGDC method. From sequence stratigraphic point of view and based on the results from geological studies, the Sarvak Formation has been sub-divided into four third-order sequences which are described and interpreted. Two main disconformity surfaces, considered as sequence boundaries, are characterized by features of karstification, dissolution-collapse brecciation, and development of paleosol horizons. Generally, positive surfaces correspond to maximum flooding surfaces and negative surfaces occur at sequence boundary. Comparison of the results shows that, the identified sequence by NCGDC method can be effectively used for discrimination and correlation of sequences in different carbonate and siliciclastic reservoirs in the field scale.
