The number of drilling rigs operating in U.S. oil fields continues to rise, increasing by six this week. 

The total rig count is now at 556, 244 more than a year earlier, according to oilfield services giant Baker Hughes. 

Drillers this week added one rig in the Permian Basin for a total of 272, with 118 rigs added since last year in the nation’s most prolific oil field. Drillers also added one rig in the Eagle Ford of South Texas, bringing the total number to 41. There are 46 rigs operating in the Haynesville shale of east Texas.

Oil production in the U.S. for the week ending Nov. 5 remained flat at 11.5 million barrels per day, according to the Energy Department.
