CEO) has entered into two major joint venture deals with natural gas company Chesapeake ( CHK - Get Report) in the Niobrara and Eagle Ford shale formations, paying more than $3 billion for the assets, and Chinese mega-cap Sinopec ( SNP - Get Report) recently followed suit, buying half of Chesapeake's Mississippi Lime assets for $1.02B in cash.
