NEW YORK, Nov 8 (Reuters) - Oil and natural gas company Apache Corp has rejected a takeover approach from an unidentified party and is working with Goldman Sachs on a defense, according to a report by Bloomberg, which cited people familiar with the matter.

The potential buyer sent a letter to Apache in the "past few weeks," according to one source cited in the report. It was not clear if the talks would resume, the report said.
