8. CNOOC ( CEO), an investment holding company engaged in the exploration, development, production, and commercialization of crude oil, natural gas, and other petroleum products, increased 11% during the past one month.

Developments: CNOOC, with a combined market value $100 billion on the NYSE and the Hang Seng, recorded a 48% year-over-year increase in third quarter net oil and gas production.

CNOOC has estimated its full-year production target in the range of 319-329 million barrels of oil equivalent.
