South Yaran to Commence Early Production

South Yaran is one of jointly owned oil fields in the West Karoun area in southwestern Iran. It has not been talked about too much.

However, its development and operation are among priorities of the Iranian Ministry of Petroleum with regard to developing hydrocarbon fields shared with neighboring countries. North Yaran field has already started production and countdown has started for the development of the southern stretch of Yaran.

Yaran was divided into two sections, North and South, due to financial restrictions following the imposition of tough sanctions on Iran. North Yaran was awarded to Persia Oil and Gas Industries Development Company under a buyback deal in 2011. It recently became operational along with the first phase of North Azadegan and Yadavaran fields. However, pursuant to a decision by National Iranian Oil Company (NIOC), the field was assigned for development to Petroleum Engineering and Development Company (PEDEC) in 2013. It is to be noted that PEDEC runs all fields located in West Karoun.

Primarily, the objective behind the development of South Yaran was to recover 50,000 to 60,000 b/d of oil and 60 mcm/d of gas after drilling 30 wells. The recovery rate was announced at 13.5%. However, Homayoun Kazemeini, who manages the development of South Yaran, said when PEDEC started developing this field it had no idea about its reservoir; therefore, an appraisal well, which was similar to exploration well, was first spudded.

The data gathered from drilling in 2015 showed that the Fahlyan layer of South Yaran had no production capacity. Therefore, the target envisaged for production from South Yaran was reduced to 25,000 b/d.

Kazemeini said new data caused changes in the plans devised for the development of the field because all plans had been worked out for 50,000 to 60,000 b/d output. Now according to new data, 21,000 b/d is expected to be extracted from Sarvak layer and 4,000 b/d from Gadvan layer.
