Latham & Watkins and Texas law firm Gardere Wynne Sewell (GWS) have secured the top roles on BP’s $5.5bn (£3.5bn) sale of several of its oil and gas fields in the Gulf of Mexico to Houston-based Plains Exploration & Production (PXP).

A GWS team led by Houston corporate partners Douglas Eyberg and Timothy Spear represented BP on the sale, while Latham took the lead for PXP.
