Premier in bid for BP field

British oil firm Premier Oil has made an offer to buy BP’s stake in the Wytch Farm oil field in south west England, according to weekend reports. BP said in May it had agreed to sell its interests in Wytch Farm and surrounding oil fields in Dorset to privately-held Perenco in a $610m (£376m) deal, a sale which is subject to partner pre-emption rights. Premier is the second largest partner in Wytch Farm behind BP.
