Crude oil output rose 26,000 barrels per day (bpd) to reach 10.43 million bpd for the week ending March 23, the EIA data showed.
"There was another climb in U.S. oil production," Thomas Pugh, a commodities economist at London-based Capital Economics, said in a note.
"Since the start of the year, U.S. output has risen by about 650,000 bpd, most of which has been exported," he added.
The U.S.' commercial crude oil inventories rose 1.6 million barrels, or 0.4 percent, to 429.9 million barrels for the week ending March 23, according to the EIA.
The market expectation was a decline of 0.3 million barrels in commercial crude stocks.
"Inventories of crude oil rose last week as imports rebounded and production grew again," Pugh said in the note.
The U.S.' crude oil imports increased 1.07 million bpd to 8.15 million bpd for the week ending March 23, while crude exports rose slightly by 5,000 bpd to 1.58 million bpd.
