Those calculations should take all of ten minutes using the sophistication of a laptop computer to determine those numbers. Not sure if you are being thrown under a bus or just trying to figure it all out using your own logic. These multi-billion dollar companies have the technology or can hire the technology to get those stats in a few weeks at most.
My advise is to STOP being an apologist for the oil companies involved and start viewing other alternatives. My take is that they are negotiating with the indies to determine buy out pricing and those negotiations are complex. Nothing to do with the geology at this point.
