Al-Omar field (Arabic: حقل العمر النفطي) is an oilfield in Deir ez-Zor Governorate, Syria.

It is located 10 kilometres (6.2 mi) north of Mayadin, east of the Euphrates river.

However, due to a lack of pressure support and overproduction in the early 1990s, the field was damaged, leading to a sharp decline in output to 16,000 b/d by 1991.

Water injection techniques were implemented from 1991 onwards, stabilizing production at a plateau of 60,000–70,000 b/d between 1994 and 1997.

It fell under the control of the al-Nusra Front and other Islamist rebels in November 2013,[3][4] then ISIS in July 2014 from Al-Shaitat clan, and ultimately the Syrian Democratic Forces (SDF) with support from the US-led Coalition in late October 2017 during the Eastern Syria campaign.
