LONDON, April 8 (Reuters) - Royal Dutch Shell Plc's agreed $70 billion takeover of rival BG Group could trigger pre-emption rights in key oil and gas fields that would erode the potential benefits of the deal for the Anglo-Dutch oil giant.
Shell said a main driver of its bid for BG Group was the gas-focused British group's position in Brazil. Two exploration blocks, named BM-S-9 and BM-S-11, account for almost all the value of BG's Brazil assets.
