Baghdad (IraqiNews.com) – The state-owned Iraqi Drilling Company (IDC) started on Thursday a major maintenance operation on well ZB-510 in the Zubair oilfield in the southern province of Basra.
The company said in a statement that it used the IDC-47 workover rig to resume repair operations on oil well ZB-510 after a suspension that lasted four months, the state-run Iraqi News Agency (INA) reported.
Workover operations are specialized technical processes designed to address the specific needs of a well. These operations focus on rehabilitating the well based on its technical condition and the approved program, aiming to restore it to operational status.
In July, Iraq’s IDC completed drilling a new deviated oil well in the Zubair oilfield as part of the Ministry of Oil’s efforts to increase output and enhance operational efficiency.
To boost the development of the Zubair oilfield, the new well was drilled to a depth of 3,846 meters with a 20-degree inclination.
The new well is part of a string of wells designed to keep production levels stable and improve the Zubair oilfield’s capabilities in the next phase.
The field has large reserves, officially estimated at over four billion barrels of recoverable crude oil. According to unofficial estimates, modern extraction technologies might increase these reserves to roughly five billion barrels.
As part of the Ministry of Oil’s attempts to prevent gas flaring and generate electricity, the oilfield has seen achievements in the recovery of associated gas, with a rate reaching 147 million cubic feet per day.
The Zubair oilfield is located onshore in Iraq and is operated by Italy’s Eni. Economic calculations indicate that production will continue until the field reaches its economic limit in 2047.
Eni and its partners are aiming to raise the oilfield’s output capacity to 700,000 barrels per day, with a long-term government objective of 850,000 barrels per day.
With a daily output capacity of around 450,000 barrels, the oilfield presently accounts for around nine percent of the country’s oil production.
