Genel Slashes Reserves Estimate for Iraqi Kurdistan Field Again

Source: www.gulfoilandgas.com 3/28/2017, Location: Middle East

Gross 2P reserves for the Taq Taq field as of 28 February 2017 are estimated by McDaniel at 59 MMbbls, compared to 172 MMbbls at 31 December 2015. Cumulative oil production from the Taq Taq field to 28 February 2017 is 207.9 MMbbls.

The further reduction in reserve estimates for Taq Taq is a consequence of a reassessment of the gross rock volume above the oil water contact and fracture porosity in the undrained Cretaceous Shiranish reservoir. This follows an analysis of reservoir surveillance data and well performance in 2016 and the first two months of 2017.

The McDaniel CPR states that there is still significant uncertainty in Taq Taq oil reserves. In particular, reserves are dependent on the Shiranish formation fracture porosity in the un-swept portion of the reservoir, which remains very difficult to estimate.

The Taq Taq field is currently producing c.19,000 bopd, compared to c.36,000 bopd at the end of 2016. Recently, key producing wells have exhibited high rates of decline as a result of water breakthrough, exacerbating the decline rate across the field.

Given the ongoing uncertainties highlighted above, the previous guidance for 2017 Taq Taq gross average production of 24-31,000 bopd is now removed. The Company currently intends to announce Taq Taq field production on a monthly basis going forward.

As a result of the reserve downgrade announced today, Genel expects to record an impairment, subject to audit, of $181 million to the Taq Taq field carrying value in its 2016 accounts.

Further detail on the Taq Taq field and the near-term development plan will be given in the Company’s results forthe year ended 31 December 2016, which are to be announced on Thursday 30 March 2017.
