From the latest Quarterly report, I'm calculating that the blended $/BOE price SEA received is $74.3/BOE.
I'd suggest that's advisable when doing any revenue projections, as opposed to using a ~$100/BOE figure like you're using, which is an exaggeration of the price of oil alone ($90/BO realised by SEA), let alone when you include the lesser valued gas.
Assuming that global market performance and oil prices remain consistent with today's levels, I do agree that SEA should look significantly undervalued in 6 months time, assuming the IPO is succesful.
