HOUSTON, July 27 (Xinhua) -- The number of active drilling rigs in the United States increased by two this week to 1,048, or 90 more than that this time last year, showed weekly data released by Baker Hughes on Friday.

Meanwhile, the number of gas rigs dipped by one, hitting 186 and the number of miscellaneous rigs remained one this week, it said.
