Baku, Azerbaijan, June 5
By Fatih Karimov – Trend:
The output capacity of Azar oilfield, in western Iran, has reached 30,000 barrels per day, Nureddin Shahnazizadeh, managing director of Iran's Petroleum Engineering and Development Company (PEDEC), said.
Iran will start early production at the oilfield, which is shared with Iraq, in the coming days, Shahnazizadeh said, IRNA news agency reported June 5.
At least 25,000 barrels per day of the production capacity will become operational this month, he said, adding that eight wells are drilled and ready for early production in the oilfield.
Azar is a specific oilfield and the most challenging field in terms of drilling, Shahnazizadeh said.
He added that the field’s oil contains a high amount of H2S which leads to corrosion in equipment and pipelines.
The Azar oilfield spans an overall area of 482 square kilometers in southeast of Mehran town in the western Iranian province of Ilam. The field is estimated to hold 2.5 billion barrels of oil in place. The volume of possible oil reserves to be excavated from Azar field is estimate to be around 400 million barrels.
Last year, Iran for the first time implemented acid fracturing operation in the field in order to increase its oil recovery rate.
Acid fracturing is a production stimulation technique that has been widely used by the oil industry. In such a treatment, acid or a fluid used in a pad ahead of the acid, is injected down the well casing or tubing at rates greater than the rate at which the fluid can flow into the reservoir matrix.
