BISMARCK, N.D. (AP) _ Officials are expecting more than 4,000 people to attend a three-day event in Bismarck highlighting the state's booming oil patch.
The Williston Basin Petroleum Conference and Expo starts Tuesday at the Bismarck Civic Center.
North Dakota Petroleum Council President Ron Ness says people are coming in from more than 40 states and countries as far away as France, Norway and Nigeria.
The event brings together engineers, geologists, investors, CEOs and government officials.
Sheri Grossman with the Bismarck-Mandan Convention and Visitors Bureau says the expo is the biggest event ever scheduled in Bismarck should inject about $1.7 million into the area.
North Dakota passed Alaska in March to become the second-leading oil-producing state in the nation, trailing only Texas.
