In more detail, IAE paid $38.5 million for 3.4 million barrels 2p (immediate production) and INA paid $176 million for 6 million barrels 2p (will produce shortly. So INA paid about twice as much per 2p barrel.
Per flowing barrel, IAE paid around $35000, whereas INA paid around $29000.
So the bottom line is that IAE paid half as much for their asset purchase, although it will take them slightly longer to get all their oil out of the ground.
