Iraq and Iran dispute.
Iraq and Iran have been in dispute over the Fakkah oil field and other adjacent fields such as the Abu Ghurab, and Buzugan since 2003. In the past, Iraq has accused Iran of "horizontal drilling" in the Fakkah field. This would entail Iran drilling into Iraqi territory to search for oil. The two sides also dispute the precise location of the border. In 2009, Iran had begun to make incursions into a disputed area of the Fakkah field but were often turned away by Iraqi workers.
On December 18, 2009, about a dozen Iranian troops crossed three hundred yards into Iraq and seized oil well No. 4 in the Fakkah Field, raising the Iranian flag on site. The incident infuriated Iraq who demanded that Iran withdraw. While the Fakkah oil field is considered shared, Iraq considers well No. 4 as theirs. The well was drilled in 1979 and initially produced per day. However, production on the well ceased in 1980 due to the Iran–Iraq War. On December 21, after a series of political negotiations, Iran withdrew from oil well No. 4.
