Abstract

Seismic data from the onshore area of Iran over the Darquain structure is used to investigate stratigraphic and structural seismic anomalies inside the Fahliyan formation (Neocomian). The data consists of a 3D grid seismic cube, acquired in the late 1990's. An integrated seismic interpretation and inversion revealed an outstanding feature in the lower part of the Fahliyan formation. This anomaly has N-S trend, parallel to Darquain structure and the results of seismic studies predict high porosity for the observed anomaly in the lower part of Fahliyan as a major oil reservoir. Recent drillings based on the results of seismic interpretation proved its potential.
