Proposals for the survey have to be made by mid-October. The survey will cover the so-called offshore marine and transition zone, centring on the Hendijan-Bahregansar area, IOOC said.
Tender documents can be collected from IOOC's Tehran offices as of this weekend, after a second announcement by the state company.
Proposals, with bid bonds of $76,300, will have to be submitted two months after the second announcement.
