I had read that the initial depleted frack only retrieves less than 10% of the available hydrocarbons. So I am not surprised that they are ramping this number in already drilled pathways. Marginal costs must be much lower.
Keeps out guys working, and OPEC fretting. It’s only a matter of time China learns this technology and exploits their hydrocarbons and others. The balance of power shifts.
Does China have big shale deposits? I didn’t know that. I thought it was mostly an American thing.
