The North Dakota Industrial Commission of the Department of Mineral Resources said 9,322 wells were in production in July, an all-time high, and nearly all were targeting the Bakken and Three Forks formations.
Lynn Helms, director of the NDIC, said the rig count decreased from June to July but the number of wells completed increased from 102 to 251, leading to an increase in oil production in the state.
The NDIC said July oil production was 27,108,258 barrels for the month, a record. A record for natural gas production was set at 970 million cubic feet per day.
The U.S. Geological Survey estimates parts of North Dakota may contain as much as 7.4 billion barrels of oil and 6.7 trillion cubic feet of natural gas. The state is in the No. 2 spot behind Texas in terms of production of natural resources in the United States.
