Methane Emission and Climate-Change
In the context of fugitive methane emissions associated with development of natural gas, whether the huge variation between conventional gas (just 0.01 % of the life-time production of a well, because, the emissions remain to be lower for conventional gas wells during completion as they have no flow-back and no drill out) and shale gas (around 2%) associated with the emissions during well completion – would remain to be a serious cause of concern in the long run – under the umbrella of climate change?
Whether, additional venting associated with liquid-unloading (of course, can be mitigated with plunger lifts) should also be considered for unconventional wells?
Assuming around 10% of the total production of the well remain to be emitted to the atmosphere as methane, during the life cycle of an average shale-gas well; would it still influence any climate-change (as it effects attenuates more rapidly due to the relatively shorter residence time in the atmosphere)?
And, how does it matter, whether, we are concerned about 20-year horizon or 100-year horizon in such cases?
