Exploratory studies on 660,000 sqkms of oil, gas fields in Iran complete

Tehran, Aug 18, IRNA -- Exploratory studies have been completed on 660,000 square kilometers out of 1,150,000 square kilometers of the oil and gas rich sedimentary zones in central, southern, southwestern and southeastern parts of Iran.

Director of the Exploration Affairs Department at National Iranian Oil Company (NIOC) Seyed Mahmoud Mohaddes told a press conference on the eve of the Government Week (August 23-29) that the study had started from the middle of the Second Five-Year Economic Development Plan (1995-2000).

Mohaddes said the feasibility project had covered the shelf and sedimentary zones in Zagros, the Persian Gulf and Oman sea shelf zones, central Iran, as well as in the environs of Kopah Dagh (Old Mount) and Dasht-e Moghan.

He said the maps of the exploratory project will be posted on the NIOC website ( for use and study by those interested.

He added that his company had entered a deal with a foreign company for joint seismographic studies on an area of more than 112,000 square kilometers in the Persian Gulf and Oman Sea.

The official said two-dimensional seismographic studies had been completed on a zone in the Oman Sea, stretching from Pakistani border to the Persian Gulf head, yielding good results which are in interpretation phase.

He said his department had completed two-dimensional seismographic operations on 13,500 square kilometers of land -- partly in Zagros and central Iran -- over the past seven years.

He added that an area of about 5,600 square kilometers which includes Darkhoein, Khangiran, Shadegan, Karanj, Ab Teimur, and Parsi gas fields, had undergone three-dimensional seismographic studies since 1997.

The NIOC official said three-dimensional studies have been completed on Azadegan oil field and the interpreted results would be available for the team in charge of the marathon project's implementation.

Mohaddes said elsewhere in the interview that 92 percent of Yadavaran oil field is covered by three-dimensional seismographic operations, due to be completed within the next 45 days.

He said 31 exploratory wells and eight detailed wells had been drilled, 23 of which proved to contain oil and gas.

He added that as a result, 15 oil and gas fields were discovered, 28 layers of which contained oil and gas.

He said contracts had been signed with foreign companies for exploration of an area of 23,000 square kilometers, including six blocks, including Anaran, Monir, Mehr, Fars, Towsan and Zavareh in Kashan, Isfahan.

He added that 6,280 square kilometers had undergone two-dimensional and about 400 square kilometers three-dimensional seismographic operations.

Mohaddes said 19 exploratory wells will be drilled in the blocks.

He said four out of the 19 wells have been successfully drilled and the operations are underway on Monir, Anaran, Mehr and Zavareh.

He put the cost of drilling operation in the six blocks at about dlrs 330 million, saying 12 foreign companies are partners in the projects.

Furthermore, he said 13 contracts have been signed with the 12 companies for implementation of the project in cooperation with domestic experts on 389,000 square kilometers of lands.

He said winners of a bid, held late last year on development of 16 exploratory blocks, would have to offer their economic and technical proposals by September 1, 2004.

He expressed hope that the exploration operations will be completed by the next 10-15 years.

Concluding his remarks, Mohaddes said the time span for drilling exploratory wells have been cut since 1997.
