$this->bbcode_second_pass_quote('', 'I') am somewhat surprised they are still at it, considering A) the US is still drilling like crazy and B)calculations such as those above showing the validity of the method in general.
just so it is understood by all and sundry, the oil industry does not give two hoots about EROEI as it doesn't instruct on whether a project can be profitable or not. The numbers they are interested in are capital costs (wells and facilities), operating costs (fixed and variable), commodity price, tarriffs, royalties and taxes. Cashflow profiles can be built for the life of a particular well/field and NPV discounted at an appropriate value (usually 10 or 15%) along with IRR and other measures such as discounted profit to investment ratio are calculated. Companies I've worked for usually look for something that will generate a minimum of $1 NPV/boe, 20% IRR and discounted profit to investment ratios greater than 0.4
At current gas prices new dry gas shale projects in some areas (eg. Quebec, BC Montney and Horn River) are uneconomic, needing prices closer to $5/Mcf. The liquid rich gas shale projects such as the Eagleford are quite profitable at current gas prices with breakeven prices just north of $2/Mcf.
