U.S. President Barack Obama ordered limited airstrikes against Sunni-led insurgents in the mountainous north of Iraq last week. In an address Saturday, the president said the strikes
"successfully destroyed arms and equipment" held by the militants.
The semiautonomous Kurdistan Regional Government last week said oil operations in the north deserved close monitoring, though were largely unaffected by the violence.
"TAQA has suspended its operations at the Atrush block as a result of recent developments and escalating instability around the Kurdistan Region of Iraq," it announced: Sunday.
Several other energy companies operating in the area have pulled non-essential staff out of the country as a security precaution.
TAQA has invested more than $300 million in a program to drill three production wells and build a central processing facility for the reserve area.
Discovered in 2011, TAQA said the block should start producing around 30,000 barrels of oil per day by next year.
