Abstract

This paper pertains to the 3D area of Kaza-Nandigama area falling in West Godavari Sub Basin . 3D seismic data of KazaNandigama area was acquired , processed and interpreted by ONGC. Authors have mapped 9 horizons from Lower Cretaceous to Oligocene top in the entire volume to decipher the structural configurations and for extracting the stratigraphic information in all sequences with an emphasis on rift fill sequences. The presence of hydrocarbons have been established in this area by wells on Kaza Horst and Bantumili Graben which produced gas from Upper and Lower Cretaceous sequences respectively. The rift fill sequences of Nimmakuru area are seen extending up to Kaza Horst.
