U.S. cash crude prices broadly fell on Friday, dealers said, as companies added more oil rigs, and offshore operators impacted by Hurricane Francine started to recover and ramp production back up.

U.S. energy firms this week added oil and natural gas rigs for the first time in five weeks in the biggest weekly rise in a year, energy services firm Baker Hughes said in its closely followed report on Friday.

Baker Hughes said oil rigs rose by five to 488 this week, while gas rigs rose by three to 97.

Meanwhile, U.S. Gulf of Mexico energy firms on Friday were lumbering back from hurricane disruptions as offshore oil and gas producers ramped up output, ports reopened, and onshore terminals accepted oil and liquefied natural gas (LNG) tankers.

Hurricane Francine shut in up to 42% of the region's offshore oil production.
