Shell has concluded another drilling campaign in Brazil. The drilling activities led by semi-submersible rig Noble Developer and supported by PSVs Tantalus Tide, UP Rubi and Vega Challenger at the CM-659 block have officially ended, with all units now being demobilized from their respective Shell contracts. The CM-659 block was acquired by Shell (40%) in partnership with Chevron (35%) and QPI (25%) on the 16th bidding round from ANP. The block is located in the pre-salt area of Campos Basin and Shell had licensed to drill up to 6 wells at the location.
