BISMARCK, N.D. (AP) — Organizers expect about 2,800 people to attend a three-day event in Bismarck highlighting the state's oil patch.
The Williston Basin Petroleum Conference and Expo starts Tuesday at the Bismarck Civic Center.
The North Dakota Petroleum Council says people come from about 40 states and a few foreign countries.
The event brings together engineers, geologists, investors, CEOs and government officials.
The attendance is expected to be down from a record 4,300 two years ago. At that time, oil was about $90 a barrel and nearly 190 drill rigs were active in western North Dakota's oil patch. North Dakota oil is now fetching less than half that, and the number of drill rigs has slipped to 25, the lowest in about a decade.
