Liquid natural gas is not oil. Moreover, liquid natural gas liquids tend to rise as a field ages so it is quite likely that crude oil production is significantly overstated by using all liquids as a proxy.Américain à Parishttps://www.blogger.com/profile/02166877752676343802noreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-31536885334293532552011-11-11T17:15:47.148-08:002011-11-11T17:15:47.148-08:00Scientist says, "Still not peak liquid fuels....Scientist says, "Still not peak liquid fuels."<br /><br />Used Car Salesmen says, "Still not peak oil (or at least not peak liquid fuels)"... and then runs quickly into his sales pitch.<br /><br />Stewart, you have a PhD.

In other words, the individual volumes of crude oil, condensate, natural gas liquids, liquid natural gas, ethanol, refinery gains, etc. that were produced in 2011.Frugalhttps://www.blogger.com/profile/02131888563915032794noreply@blogger.comtag:blogger.com,1999:blog-5235419263414453422.post-11603699060717792822011-11-11T09:55:53.096-08:002011-11-11T09:55:53.096-08:00As has been discussed earlier, while total liquids...As has been discussed earlier, while total liquids is an important parameter, perhaps more important is total net energy in the form of liquids. A recent study (Gagnon, N., C. Hall, and L. Brinker, 2009, A preliminary investigation of energy return on energy investment for global oil and gas production, Energies 2009, 2, 490-503) sheds some light on this. My interpretation of data in this article is that global EROI for oil and gas declined from ~35 in 1999 to ~18 in 2006. If this rate of decline is realistic for liquid fuels, and has continued, then the net energy of liquid fuels in 2011 could be comparable to or even less than the net energy of liquid fuels in 2008.Mike Aucotthttps://www.blogger.com/profile/05692592170835103639noreply@blogger.com
