Jean Laherrere has posted the following charts and comments on Bakken and World oil reserves. EIA proved reserves on Bakken (ND +Montana) plus cumulative production have changed at end : -2012 3754 Mb -2013 5701 Mb -2014 7203 Mb -2015 6671 Mb As shown in this graph in red squares, together with HL ultimates, USGS estimates and cumulative production. ThisEIA CP+RR value (which is assumed to trend towards the oil ultimate) has increased sharply from 2012 to 2014 and has decreased in 2015 (this decrease may continue towards which value?). Proved reserves depend upon the oil price. Its variation indicates that its reliability is poor: No one knows how to estimate unconventional reserves as LTO because there is not enough historical series to verify if the method is right. EIA reports Bakken reserves only since 2011. Unconventional oil reserves are in unconventional reservoirs under unconventional trapping (no conventional water […]
