'Exxon Mobil in advanced talks for $60 billion acquisition of Pioneer'

Exxon Mobil is in advanced talks to acquire Pioneer Natural Resources in a deal that could value the Permian shale basin producer at about $60 billion. The acquisition would be Exxon's biggest since its $81 billion deal for Mobil in 1998 and would expand its footprint in one of the most lucrative regions of the US oil patch.
