Sirri A

Location

The Sirri A oil field is located in the Persian Gulf, offshore Iran. Specifically, it is situated near Sirri Island, which is 72 kilometers south of Bandar Lengeh and 40 kilometers west of Abu-Musa Island.

Operator and Ownership

The Sirri A oil field is operated by the Iranian Offshore Oil Company (IOOC), a subsidiary of the National Iranian Oil Company (NIOC).

Field Details

• Sirri A is part of the broader Sirri oil fields, which include several other fields such as Sirri C (Sivand), Sirri D (Dena), and Sirri E (Esfand).
• The field is located in shallow water and is classified as a conventional oil field.

Production

• Production from the Sirri A field, along with Sirri E, has been significant. The fields have recovered 61.69% of their total recoverable reserves as of the last available data. Peak production was achieved in 2003, and based on economic assumptions, production is expected to continue until the field reaches its economic limit in 2050.
• The current production from the Sirri region, including Sivand and Esfand fields, has increased by 20% to reach a capacity of 111,000 barrels per day.

Infrastructure

• The oil from the Sirri A field is gathered and processed along with other nearby fields. For instance, the oil from the Alvand field is transferred to the Nasr platform, and then to Sirri Island via a 16-inch pipeline.
• The Esfand (Sirri E) field, which is part of the same complex, has 5 offshore platforms including 3 well platforms, a production platform, and a flare platform.

Reserves

• While specific reserve figures for Sirri A alone are not detailed, the broader Sirri E field has significant reserves:
  • Original oil in place: 2,267 million barrels
  • Primary reserves: 176.8 million barrels
  • Secondary reserves: 739.9 million barrels
  • Recoverable reserves: 916.7 million barrels.

History

• The Sirri E field, which includes Sirri A, was discovered in 1972. The field started production in 1999.

Contractors and Projects

• The IOOC has collaborated with various contractors for development and enhancement projects. For example, a $120 million engineering, procurement, and drilling contract was signed in 2018 with PetroIran Development Company to enhance oil production in the Sivand and Esfand fields, which was completed in 2023.

Current Status

• The field is currently operating, with ongoing efforts to maintain and enhance production. The IOOC continues to manage the exploration, production, and development activities of the field.
