Genel Energy: Taq Taq reserves update
Published by David Bizley,

Oilfield Technology,
Genel Energy issues the following announcement in respect of its reserves position at the Taq Taq field (Genel 44% working interest).
As previously stated, the Company commissioned an updated Competent Person's Report (‘CPR’) for the Taq Taq field from McDaniel and Associates.
The CPR has been completed and is available from the Company's website at www.genelenergy.com/investor-relations/results-reportspresentations.
Gross 2P reserves for the Taq Taq field as of 28 February 2017 are estimated by McDaniel at 59 million bbls, compared to 172 million bbls at 31 December 2015. A reconciliation from the reserves reported in the CPR released in April 2016 to the updated estimates in the CPR published earlier, is shown in the following table:
| Gross oil reserves (million bbls) | 1P | 2P | 3P |
| 31 December 2015 | 60.0 | 171.8 | 416.4 |
| Production | (23.8) | (23.8) | (23.8) |
| Technical revisions | (10.4) | (89.0) | (297.6) |
| 28 February 2017 | 25.8 | 59.1 | 95.0 |
| Some totals may not add due to rounding. |
Cumulative oil production from the Taq Taq field to 28 February 2017 is 207.9 million bbls. Of this figure, 1.8 million bbls has been produced in 2017. 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 bpd, compared to c.36 000 bpd 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 bpd 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 US$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 for the year ended 31 December 2016, which are to be announced on Thursday 30 March 2017.
