This was achieved following the installation of the first sucker rod pump (SRP) in one of the wells of the oilfield, Mohammad-Ali Ajdari added, Shana reported.
He noted that following the installation of the first electrical submersible pump (ESP) in this field a year ago, the first SRP was also installed in a trial operation nearly one month ago.
“After assessing the performance of the pump based on the characteristics described by the manufacturer and in view of the production conditions of the reservoir and the well, the 72-hour test with a flow rate of 750 barrels per day was approved.”
Ajdari listed some of the advantages of these pumps as simplicity and ease of installation and extraction, durability and high energy efficiency at lower depths and flow rates, as well as low maintenance and capital costs compared to other methods of oil lifting.
This domestically-manufactured pump has helped increase production from the well No. 14 of the North Yaran oilfield by at least 500 bpd and plays an effective role in boosting the field’s overall production capacity by raising the well pressure, he added.
The first ESP was installed in well No. 4 of the oilfield in mid-August 2019, which increased the field’s output capacity by 1,000 bpd.
The development project of the North Yaran oilfield began in 2016 with a daily production of 30,000 bpd. However, after a while, the field’s production suffered a slight decline.
Yaran is one of the five oilfields located in the West Karoun region. Comprising two parts, namely North Yaran and South Yaran, the oilfield is located 120 kilometers west of Ahwaz, the capital city of the southwestern province of Khuzestan, in proximity to the common border with Iraq.
The field is adjacent to Azadegan oilfield in the east and Iraq’s Majnoon oilfield in the west.
The five oilfields located in the West Karoun region are North Azadegan, South Azadegan, North Yaran, South Yaran and Yadavaran.
