In 2012, we embarked upon a frontier exploration drilling programme focused on the Atlantic Margin as part of the company's exploration strategy to focus on frontier and emerging basin acreage. Along the Atlantic Margin, we also hold acreage offshore Western Sahara and the Republic of Ireland.

In 2013, we farmed-in, as operator, to frontier acreage offshore Senegal, acquiring a 65% interest in three blocks with a combined area of 7,000km2. Cairn was the first to drill in deepwater offshore Senegal which remains relatively underexplored.

In 2014, we made two basin opening discoveries in the first 12 months of operation. One of these discoveries, the SNE field, was the largest global oil discovery of 2014.

In 2015, we acquired 3D seismic and recommenced drilling. In 2016 four wells were completed ahead of schedule and under budget. Cairn completed the drilling of a further four, successful wells. With two drilling programmes now completed in Senegal, a third is underway which commenced in 2017 and which is focused on additional exploration and appraisal activity to further increase this already significant resource base.

Current 2C in place resources are estimated at more than 2.7 billion barrels and the ongoing exploration and appraisal programme will further define the recovery potential of the SNE field. Multiple exploration prospects have been identified and we estimate further block wide exploration potential of ~500 million barrels of oil gross mean risked resource.

We operate and have a 40% Working Interest (WI) in the three blocks offshore Senegal (Sangomar Deep, Sangomar Offshore, Rufisque Offshore) alongside our Joint Venture (JV) partners Woodside 35% WI, Far Ltd 15% WI and the Senegal National Oil Company, Petrosen 10% WI.

With our JV partners, we submitted a three-year evaluation work plan to the Government of Senegal in 2015. As part of this plan, we expect to submit an outline timetable for development and an Exploitation Plan in 2018, a Final Investment Decision within twelve months thereafter and first oil in the period 2021-2023.
