The number of oil rigs in the U.S. increased for the 10th time in the past 12 weeks, according to oilfield services company Baker Hughes data released on Friday.
The oil rig count in the country rose by seven for the week ending April 13, the company said.
With the latest increase, the number of oil rigs, which indicates the short-term change in the U.S.' oil industry, is now at 815.
The current level also shows around 19 percent increase in the oil rig count, which stood at 683 in the same period last year.
Despite the increase in the number of oil rigs, crude oil prices did not lose much of their daily gains on Friday.
International benchmark Brent crude traded at $72.73 per barrel with a 1 percent daily gain at 1330 EST (1730 GMT).
American benchmark West Texas Intermediate (WTI) was at $67.53 a barrel at that time with a 0.7 percent gain.
