U.S. oil company Chevron Corp. announced it has detected a small crude leak at the same field off Brazil’s coast where another spill occurred last November.

Company spokespersons said they detected a “small new seep” at the Frade field, located 120 kilometers (75 miles) off the coast of Rio de Janeiro state in the Campos basin, Brazil’s largest oil region.

Chevron said it immediately acted to recover the leaked crude, which seeped out of a new crack in the ocean floor, about three kilometers (1.85 miles) from the site of the November spill.
