(Corrects paragraph 1 to show Eni (not Eni and Essar) is expected to drill at block 115/09 after clarification from PetroVietnam)

HANOI, March 1 (Reuters) - Eni Vietnam B.V., a unit of Italian energy group Eni, is expected to start drilling at the Dan Tranh-1X well in Vietnam's offshore oil block 115/09 from late this month, state oil firm PetroVietnam said on Tuesday.

PetroVietnam will invite Essar to bid for Vietnam's other offshore blocks late this year or early next year, the company said in a statement, following a meeting in Hanoi between executives of the two companies. (Reporting by Khanh Vu; Editing by Martin Petty)
