In January 2019, Oil Search Ltd agreed to pay USD 8-million to acquire a 50% working interest in 195,200 acres (789 sq km) on the North Slope from Armstrong subsidiary Lagniappe Alaska. The leases were acquired by Lagniappe in November 2016 from the NS2018W oil & gas lease sale. Lagniappe was founded by Armstrong Energy LLC owner Bill Armstrong for the sole purpose of participating anonymously in the 2018 lease sale. Oil Search had agreed to establishing an Area of Mutual Interest with Armstrong when it entered the state through the acquisition of the Pikka acreage located to the west. The AMI granted Oil Search an option to acquire a 50% working interest in acreage acquired by Armstrong.  In November 2018, Lagniappe Alaska LLC submitted high bids on 120 tracts and was preliminarily awarded the rights to the leases by the Alaska Division of Natural Resources (ADNR) at the North Slope Areawide Oil & Gas Lease Sale (NS2018W), held on 15 November 2018. The Lafayette, Louisiana-based company dominated this yearâs auction, bidding a total of USD 14,143,315.20 for the 120 tracts that cover 195,200 acres (789.94 sq km) for an average bid per acre of USD 72.45. Lagniappe Alaskaâs acreage position forms a contiguous block starting about 5 km (8 km) south of the Savant Alaska-operated Badami Unit and a little west of the Arctic National Wildlife Refuge. Lagniappe Alaska was by far the most active bidder of this sale that saw 147 bids on 133 tracts spanning 223,680 acres (905 sq km). The sum of the high bids accepted by the ADNR came to USD 27,313,721.60.
