Upon receipt of the necessary regulatory approvals, Shell began drilling the first well of a two-well campaign in October, 2015. The Cheshire well is being drilled in a water depth of 2100 metres and is the first exploration well drilled offshore Nova Scotia in about a decade. Shell has contracted the Stena IceMAX drillship, a dynamically positioned mobile offshore drilling unit suited to the North Atlantic environment and deep water depths, to drill these wells.
