The number of oil rigs in the U.S. decreased by 1 this week, from the previous week, according to data released by oilfield services company Baker Hughes on Friday.
The oil rig count in the U.S. reached 788 for the week ending June 14, from 789 the week before, the data showed.
International benchmark Brent crude was trading around $61.39 per barrel at 1150 GMT on Friday, while American benchmark West Texas Intermediate (WTI) was at $54.24 a barrel at the same time.
The EIA data also revealed that U.S. crude oil production remained near the record high level of 12.3 million bpd (mbpd) for the week ending June 7, signaling that glut of supply in the global oil market is to remain strong until the second half of 2019.
However, both Brent crude and WTI posted 2.23% increase on Thursday after two oil tankers were attacked in the Gulf of Oman.
The attacks, which came after a month when four tankers were attacked in the region, intensified worries amid secure supply of oil from the world's largest oil transport chokepoint -- the Strait of Hormuz.
