Kerala-Konkan (KK) is a Category III basin with • Basin datasets and studies:
entirely undiscovered in-place, that calls for
intense exploration for a potential discovery. As of 31.03.2025, NDR has archived primary
datasets of 154,002 LKM 2D seismic, 13,717
Kerala-Konkan Basin is characterized by SKM 3D seismic and 20 conventional wells (all
carbonate-siliciclastic shallow to deepwater exploratory). Multiple flavours of reprocessed
sediments. The basin covers mainly the offshore seismic datasets are also archived whenever the
provinces with isolated fringes of Miocene and same are provided by E&P Operators.
younger sediments in coastal onland area.

Deepest play is the Early Cretaceous and
shallowest is the Oligo-Miocene.

Resources are entirely undiscovered and half
of total resources envisaged in Late Cretaceous
play below basalts.
Poor sub-basalt imaging can be addressed by
long-offset seismic survey, magneto-telluric,
controlled source electromagnetic surveys.
Shelfal areas around Cochin Low in Kerala sub-
