Comparing Chesapeake with CNOOC is like comparing water and wine.
Chesapeake is an experienced gas operator. At the time CHK needed to find large quantities of oil fast, due to high debts. CHK was really operating on borrowed time, in the end they did a fire sale on assets to pay off debt. With tonnes of cash, CNOOC bought some of the distressed assets.

CNNOC's ambition is to learn & master shale oil extraction and hopefully one day bring the skills and technology back home to China. They have all the cash and time.
