Hendijan is a shallow water oil field located in the north-western portion of the Persian Gulf, approximately 15km away from the Iranian shoreline. It is believed to contain one of the richest natural oil reservoirs in Iran.
Owned and operated by Iranian Offshore Oil Company (IOOC), a subsidiary of National Iranian Oil Company (NIOC), the Hendijan field currently produces approximately 30,000 barrels of oil per day (bopd).
IOOC plans to increase the field’s output to 50,000bopd through additional wells and platforms.
Hendijan oil field location and development background
Hendijan is one of the oil fields in the Bahregan area of Iran that also hosts the Bharegansar, Nowruz, and Sorush oil fields. The Hendijan oil field is located 10km north-east of the Bahregansar platform.
Oil production from the Bharegan area was started in the late-1950s, while the Hendijan oil field commenced production in 1970 under the operatorship of Société Irano-Italienne des Pétroles (SRIP), a joint venture (JV) between National Iranian Oil Company (NIOC) and Agip (now Eni), an oil company based in Italy. IOOC became the operator of the field in 1980.
The offshore facilities in the Bharegan area were severely damaged during the Iraq-Iran war, which began in September 1980.
In the post-war period, oil production was resumed from the Nahr-Umr formation of the Hendijan field and later from the Ghar/Asmari and Sarvak formations.
Hendijan oil field development details
The Hendijan offshore field is developed with nine production wells and the Central Hendijan production platform (CHP).
Crude oil and associate gas extracted from the field is transferred via a 10km-long and 12in-diameter subsea pipelines to the Bahregansar offshore complex. Oil from the Hendijan as well as the Bahregansar field undergoes preliminary treatment at the Bahregansar central platform, before being pumped onshore via a 16in subsea pipeline to Bahregan for further treatment and storage.
IOOC has been expanding the field as part of the Hendijan master development plan, which was prepared following a full field simulation study in 2005.
Early production from Northern Hendijan oil field (HD6 Onshore project)
Early production from the Northern Hendijan oil field, which is also known as the HD6 onshore project, was initiated in 2012.
The project involved the installation of an unmanned new oil gathering platform, which was bridge-connected with the CHP, as well as the HD6 onshore wellhead for three new development wells.
The HD6 onshore wellhead area is connected with the new oil gathering platform located at a distance of 7.5km through two 8in-diameter pipelines and one 6in-diameter pipeline.
Power for the HD6 wellhead area is supplied through local diesel generators, while the new oil gathering platform is electrified through a subsea electrical cabling from the Bahregansar production platform via the CHP.
Details of Hendijan platforms seven and eight
Two new wellhead platforms named Hendijan-7 and Hendijan-8 are being installed to increase the field’s production capacity to 50,000bopd.
Construction of the topside of both the platforms was nearing completion at the Bandar Abbas Yard of Iran Ship Building & Offshore Industries Complex (ISOICO) in the Hormozgan Province, as of mid-2019. The installation of new platform structures includes approximately 4.5km of 12in-diameter sea flow lines and 26km of seabed cables.
ISOICO was awarded the engineering, procurement, and construction (EPC) contract for the new Hendijan platforms, while Jamm Design and Development (JDD) was responsible for detailed engineering of the platforms.
JDD engaged Aker Engineering Malaysia and Rahbord Energy to provide design and engineering services.
The EPC contract for the HD6 Onshore project was awarded to a JV between Samandis Company and Hirgan Energy. Samandis was the main contractor, while Hirgan Energy served as the consultant.
Pegasus Qeshem and Petro Barasun International were engaged for the design and installation of subsea pipelines, while Pars Petro Zargos was contracted for the master development plan for the Hendijan oil field.
