The Hendijan offshore field contains one of the richest oil field reservoirs in the country and is currently producing approximately 30,000 barrels of crude oil per day (bpd).
It is operated by Iranian Offshore Oil Company (IOOC), a subsidiary of National Iranian Oil Company (NIOC).
The oil field is located in shallow waters of the north-western part of the Persian Gulf, offshore Iran, approximately 10km north-east of the Bahregansar platform and 34km south-west of the Tangu field.
Hendijan oil field development details
The Hendijan oil field is operated through nine production wells drilled from an oil gathering platform and a central production wellhead platform weighing 3,600t. Both the platforms are unmanned and connected through a bridge. The first production from the field was achieved in 1970 from the Nahr-Umr formation. Production from the Ghar, Sarvak, and Asmari formations happened subsequently.
The subsea production system includes a manifold platform comprising two 12in risers, two 6in J tubes, pig launchers, shutdown valves, distribution manifold, and hydraulic power pack unit.
Hydrocarbons produced are transported to the Bahregansar field complex through 10km-long subsea pipelines with diameters of 10in and 12in, where crude oil and associated gas is separated. The treated hydrocarbons are transported to the onshore Bahregan Base, along with those produced in the Bahregansar field, for processing through a 16in subsea pipeline.
Details of the onshore early production system at Hendijan
As part of the project, an onshore early production system named HD6 has been installed 7.5km away from the oil gathering platform, the HD6 onshore wellhead facilities being powered by local diesel generators. This included the drilling of three development wells and the installation of two pipelines measuring 8in and 6in in diameter.
The hydrocarbons from HD6 onshore were transferred to the oil gathering platform through multi-phase flowlines and then on to the central production platform. The hydrocarbons for processing that originated from the central production platform were exported to the Bahregansar production platform through a 12in diameter pipeline.
IOOC awarded the engineering, procurement and construction (EPC) contract for the Hendijan oil field development to Iran Ship Building & Offshore Industries Complex (ISOICO).
ISOICO was the main contractor, while Jamm Design and Development Company (JDD) was subcontracted to carry out the detailed engineering.
JDD then subcontracted Aker Engineering Malaysia to provide the basic design, while Rahbord Energy was subcontracted to review the design and provide detailed engineering services.
A joint venture (JV) of Samadis Company and Hirgan Energy received an EPC contract from IOOC for the development of the HD6 onshore project. Shafagh Hormoz Mehr Gostaresh Industries Procurement and Construction Company (GIPC) procured and supplied various components.
Darya Fan Qeshm Industries Company (SADAF) received a contract for the renovation and painting of Hendijan platforms in November 2017. Work included repairing damaged steelwork, painting platforms, grit blasting and recoating of corroded areas. The platforms were constructed in the ISOICO yard at Bandar Abbas in Hormozgan Province.
Pars Petro Zagros was contracted for the master development plan for the field, while Pegasus Qeshm was responsible for the mechanical design of the crude pipeline.
Bahr Gostaresh Hormoz constructed and laid pipelines and risers.
Simeng, PetroBarasun International Company and Javidan Energy Kish were also involved in the development of the project.
