Nicp, theres no simple answer for you on CO2. From what we know of Dongfang they have various natural gas compositions at different well sites and yet are extremely commercial.

Its likely our location has some advantages being nearer the originating source of hydrocarbons but we will probably see varying levels of CO2 in diferent wells. So if our exploration well has overly high levels of CO2 it won't be game over but it won't be great for the sp in the short term.

Typically most gas fields have a CO2 component. 3% is seen as quite acceptable, 10% is seen as a pain in the reservoir. What it comes down to is what seperation equipment is required on the production platform. Higher levels of CO2 mean more seperation cost but if a development plan is in place then its commercial feasibility will have been given the green light.
