BISMARCK, N.D. (AP) _ The number of oil drilling rigs at work in North Dakota is leveling off, and a state regulator says that's a good thing.
State Department of Mineral Resources director Lynn Helms says the number of rigs working in western North Dakota has ranged between 205 to 215 during April, May and June.
Helms said it ``appears the rig count ... has leveled off'' in the low 200s.
And Helms says that's OK, because the pause ``will allow infrastructure and various other things to catch up.'' North Dakota's oil boom has put a lot of strain on local road and bridge networks.
Oil production is still rising. Companies produced an average of almost 640,000 barrels a day in May, and there are close to 7,000 producing wells.
