On 10 November 2019, the Iranian Government announced that Iran had made a new discovery named "Namavaran" in Khuzestan Province, south-west Iran. The find, at this time, is presumed to be oil in the Oligo-Miocene Gachsaran or Asmari formations with a thickness of ~80 m which encompass parts of existing fields including Mansuri, Sepehr, Susangerd and Ab-E-Teimur. The new reservoir is understood to have been first encountered by the Ab-E-Teimur 35 outpost well which was drilled in 2016/2017 and then has been subsequently appraised by the recently drilled Mansuri West 1, Sepehr East 1 and Susangerd East 1 exploration wells. Iran has announced additional "reserves" of 22.2 billion barrels of oil, this is believed to be an in-place figure and recovery factors are expected to be low at ~10%.
Press has been rife with reports of a super-discovery in Khuzestan, designated Namavaran and assumed made by NIOC. The fields reservoir reportedly sits at a depth of 3100m with an average thickness of approximately 80m. The massive reserves quoted (53 Bbo) are thought to be attributable to parts of the Mansuri, Sepehr, Susangerd and Ab-E-Teimur fields, in the Oligo-Miocene Gachsaran or Asmari Fm's. The new reservoir would feature an already-respectable 22.2 Bbo of additional reserves, assumed to be in-place, possibly ~10% recovery factor.
