Continental Resources first well flowed at an average rate of 693 barrels of crude oil equivalent per day in its initial week of production in May.
The second well, Mathistad 1-35H, began production on July 4 and flowed at an average rate of 1,095 barrels of crude oil equivalent per day, with 90 percent of production being crude oil and 10 percent natural gas.
Natixis Bleichroeder analyst Curtis Trimble said the latest results from the Three Forks/Sanish formation increased the productive profile of the Bakken Shale area.
"Future wells will be closer to the 600 to 1000 barrel a day level versus previous wells that were averaging about 450 barrels a day," Trimble said.
Continental is the largest leaseholder in the Bakken Shale play with about 500,000 acres in North Dakota and Montana.
