Farzad A and B joint gas fields are located in the Farsi block within the border of Iran and Saudi Arabia and at a distance of about 20 km on both sides of the Farsi Island. The distance of these fields from the nearest coast (Berikan) is about 100 km. The Iranian share in Farzad A is approximately 25% and in Farzad B is roughly 75%.
The gas is sour in the two offshore fields with high sulfur, carbon dioxide and nitrogen content. Farzad A Field is estimated to hold 12 trillion cubic feet of dry gas in its reserves while Farzad B is believed to have roughly 23 trillion cubic feet of gas and small amounts of gas condensate in its reserves.
Farzad B Gas Field Development Plan
Farzad B joint gas field is located in the Farsi block within the border of Iran and Saudi Arabia and at a distance of about 20 km on the east side of Farsi Island. The distance of the field from the nearest coast (Berikan) is about 100 km. The amount of gas in place in Farzad B field is estimated at 23 trillion cubic feet.
Farzad B gas has high levels of sulfur, carbon dioxide and nitrogen impurities, which are much higher than those in South Pars. Also, the amount of gas condensate is much less than South Pars.
Contract for Developing Farzad B Field:
The 60-month contract for the development of Farzad B Field was struck with Petropars Company in the form of the third generation of buyback contracts on May 17, 2021.
The project aims to produce 1 billion cubic feet of sour gas, 5,000 barrels of gas condensate and 1,400 tons of sulfur per day. The liquids produced from the field’s reservoir is sent to Tombak Coast and after separating the condensate, it is distributed between the five Pars 2 Kangan refineries to compensate for the feedstock shortage of the existing plants. The produced condensate is also sent to the two refineries of South Pars phases 12 and 19.
Offshore facilities include a main wellhead platform with liquid separation facilities, an ancillary wellhead platform with minimal facilities and a 3-kilometer 20-inch offshore pipeline to connect the ancillary platform to the main one, a 36-inch offshore pipeline of approximately 230 km length to transport sour gas to land and a 10-inch offshore pipeline that is approximately 230 km long to transport liquids to onshore facilities.
The onshore facilities include plants for receiving sour fluid from offshore platforms and condensate separation facilities along with the related ancillary facilities and onshore pipelines for transporting gas and condensate to refineries located in the Pars 2 region.
The following three management contracts (MC) were concluded and executed with Petropars Company:
-Conceptual studies of the project by an international consultant to prepare the field’s master development plant (MDP)
-Reservoir and drilling studies by international consultants to prepare the field’s MDP
-High-precision seismic survey by a domestic contractor for the first time in the country
Due to the unidentified state of the Farzad fields and the lack of information about them, as well as geological complexities, drilling challenges, reservoir temperature and high pressure and the problems caused by high levels of gas impurities in the fields and the possibility of elemental sulfur, appraisal well drilling to obtain information about Farzad B Field as well as conducting basic design studies are currently on the agenda of Petropars Company.
