The Khursaniyah Gas Plant came on stream in April 2010. It was designed to process 1 billion standard cubic feet per day (scfd) of associated gas from the Abu Hadriya, Fadhili, Khursaniyah, Marjan, Safiniyah and Zuluf fields.

The plant is integrated with Khursaniyah Central Oil Processing Facilities to minimize required utilities and capture synergies.

Khursaniyah Gas Plant was expanded in order to process gas from the offshore Karan field. Karan is the first non-associated offshore gas field project developed by Saudi Aramco in the Kingdom.

The project is located about 140 kilometers north of Dhahran, and includes facilities to transport gas from the field via a 110-kilometer subsea pipeline to onshore processing facilities at the Khursaniyah Gas Plant.

Gas is processed through three trains, each with a capacity of 600 million scfd, at the Khursaniyah Gas Plant. The trains include facilities for gas sweetening, acid gas enrichment, gas dehydration, and supplementary propane refrigeration. In addition, the facilities include a cogeneration plant with boiler, sulfur recovery unit with storage tank, substations and a transmission pipeline linked to the Kingdom‘s Master Gas System.

In 2011, the Karan offshore platforms, power facilities, subsea pipelines, and gas processing facilities located at Khursaniyah Gas Plant achieved partial mechanical completion. This allowed for the production of 400 million scfd of gas by mid-year.

In early 2012, the successful start-up of Karan gas processing facilities at Khursaniyah, seven weeks ahead of schedule, increased processing capacity to 1 billion scfd.

Karan was completed in 2012 ahead of schedule and under budget, reaching a full peak production capacity of 1.8 billion scfd, all of which is processed through the new section of the plant that is dedicated to Karan.

At the same time, the original section of Khursaniyah was also expanded to include gas from Manifa so that today Khursaniyah can handle a total of 2.88 billion scfd.
