ONGC's Intrinsic Value Is . . .

ONGC’s management, in its recent analyst call, mentioned that they expect their oil and gas production to increase by 20% from 39.45 mmtoe (which is short for million metric tons of oil equivalent) to 47 mmtoe in the next 3 years. This is a 20% increase in terms of volume.

But how much increase does this imply in terms of revenue growth?
