Another deal in the Williston Basin was out a few days ago with very positive implications for ZAR's North Dakota asset.
NOG paid US$52 million (US$40 million in cash and 6 million in shares valued at US$2 per share) and acquired 1,380 boepd production including 1,319 net acres.
This is NON-operated production which is a big minus versus ZAR's operated production in North Dakota.
NOG's deal translates into US$37,700/boepd or CAD$48,200/boepd for a NON-operated asset. Actually, NOG bought many small working interests in many wells, so we talk about small working interests here and there without any control on these wells:
"On April 26, 2018 Northern announced that it had entered into a definitive agreement to acquire producing assets and acreage in the core of the Williston Basin in North Dakota for total consideration of $40 million in cash (subject to adjustments) and 6 million shares of Northern common stock. The assets, which are expected to generate approximately $19 million of cash flow from operations in 2018, had estimated February production of 1,380 Boe per day and included 1,319 net acres that are 100% held by production with an average net revenue interest of 86%.
