The number of oil rigs, an indicator of short-term production in the country, rose by one to reach 683 for the week ending March 13, from 682 the previous week.
This marked the second week in a row that the oil rig count in the U.S. showed an increase.
However, the number of oil rigs in the country is still 18%, or 150, less than the same time a year ago when it stood at 853.
At Friday's close, international benchmark Brent crude stood at $34.72 per barrel with a 4.5% daily gain, while American benchmark West Texas Intermediate ended the day at $32.97 a barrel with a 4.6% increase.
