$this->bbcode_second_pass_quote('', 'Y')ou really are a shill aren't you. A barrel of unconventional oil IS NOT equivalent to a barrel of conventional oil in several respects.
Extraction rate, weight, amount of processing necessary, how much energy is required to extract and process compared to the amount of energy actually obtained, amount of water used in extraction, sulphur content, etc.
You are so full of it, seems no matter what subject you are talking about.
And by the way, this thread is about OPEC members lying about their reserves, and you keep trying to change the subject.
Ok, first of all we were discussing reserves. By definition reserves are "economically recoverable". The cost that it takes to produce a particular barrel of oil (Finding and development as well as operating cost) determines how economic it is. At current oil prices the majority of heavy oil around the world is economically recoverable which of course takes into account all of the costs incurred including upgrading, steam etc.. As price drops certain types of heavy oil that have higher extraction prices (eg. SAGD projects) and require higher cost upgrading are no longer economically recoverable and hence companies take reserve write-downs (this happened in 2008). That being said if the barrels are economic regardless of any other concern they are equal as far as the notion of how much "reserves" a particular country has which is exactly what the argument was about.
All hydrocarbons have different cost profiles. There are a number of lighter oils that cost more to find and produce than some of the shallow heavy oils (example would be the sub-salt fields in Brazil). There are heavy oils in places like Colombia that have low API but also low viscosity and thus flow without any energy assistance and hence are as cheap to find and produce as their higher API counterparts. There are probably no two oil fields in the world that have the exact same F&D and operating cost profile, it is more of a continuum than a two party grouping.
And I will point out once again the notion of EROEI has absolutely no place in the discussion of reserves. Petroleum economics work under the understanding of international standards of accounting practice and not on the basis of "energy balance" and it is petroleum economics that determine whether something is a reserve or not. You need to familiarize yourself with the technical terminology prior to pretending to be an expert.
It amazes me that you spout off with so much confidence when you have so little understanding of the subject matter.
And again, I was responding to something you posted....I didn't change the subject, you did.
