Tange-Bijar & Kamankouh gas field is located in Zagros Mountains in west of Iran, 125 Km from Kermanshah, 60 Km from Ilam. This field is in production stage to supply required gas for some parts of western provinces of Iran. The produced gas from this field is sour and consists of high percentage of CO2 and H2S and also the formation water includes high amount of CL- ions. Tange-Bijar gas field has been developed in a wide area of Zagros highlands, which the distance of production wells are about 15 Km.
In phase 1 of Tange-Bijar gas field production, produced gas from 5 wells (well No. 3, 5, 8, 9 and 11), is entered to Tange-Bijar Central Facility (TCF) to separate gas, gas condensate and water in a slug catcher, separated gas is transferred to ISF facilities via a 18-inch pipeline. ISF facilities is located 40 Km away from TCF.
Separated gas condensate in slug catcher is sent to a three phase separator in order to separate remaining water. Produced gas condensate from three phase separator is pumped to ISF facilities by a transfer pump and via a 6-inch pipeline.
In order to separate probable associated liquid, submitted gas from TCF is entered to a slug catcher in ISF facilities. Gas from slug catcher is delivered to Ilam refinery.
Due to recent accidents and explosions at TCF, the intend of this project is to study, evaluate, trouble shoot and introduce solutions to the current situation in flow lines from wells to TCF, TCF facilities, gas transmission pipeline from TCF to ISF and ISF facilities with the normal operating capacity of 7 MMSCMD produced gas in ISF battery limit. With consideration of 3 additional production wells and increasing capacity to 10 MMSCMD of produced gas, the flow lines from wells to TCF, TCF facilities, gas/condensate transmission pipelines from TCF to ISF and ISF facilities will be re-studied and a basic engineering package will be provided in the next phase of the project.
