There’s an interesting bit in the table in David’s article above concerning ultimate production in Chinese fields. Dagang is shown as having an estimated URR as 1.5 Gb, but cumulative production by 2050 of 1.6 Gb. Similarly, Liaohe has an URR of 5.0 Gb, but a cumulative production by 2050 of 5.1 Gb, while Zhongyuan has an URR of 1.3 Gb, but a cumulative production by 2050 of 1.5 Gb. Can anybody explain why the cumulative production by 2050 for these fields will go beyond their URR? Dennis Coyne says: 09/20/2016 at 10:44 am An obvious suggestion is that the URR estimate is too low or the output assumptions for output from 2008 to 2050 are too high. Often a URR based on the HL method results in a […]
