Abstract

Structural interpretation of 3D seismic data in Gandhar-Nada area has brought out imprints of compressional phase during Late Paleogene-Neogene period. The prominent Gandhar nosal feature is inferred to be evolved by structural inversion during Miocene whereas Nada structure is formed by compression in Eocene time. Structural readjustment during post-Miocene has resulted in the formation of Broach depression. Prior to these episodes of deformation, a large scale proto-Tankari depression is inferred to be existing in this area. The restructuring prior to hydrocarbon migration has played a major role in hydrocarbon accumulation
