The discovery of hydrocarbon accumulation in Deccan<br />
Traps has opened up a large area for further exploration<br />
of Basement in Kutch offshore. This will also augment gas<br />
reserve for development of GK-28/42 area.<br />

This discovery in NELP block, GK-OSN-2010/1 has established<br />
presence of <strong>Hydrocarbon</strong> in Early Eocene Jakhau Formation in<br />
the area <strong>and</strong> has opened up the area for exploration<br />
