Tendrara Volume Certification - Preliminary TE-5 Horst Results

Sound Energy, the African and European focused upstream gas company, is pleased to announce receipt of the preliminary results of the resources certification in relation to the TE-5 horst core volumes at the Company's Tendrara asset, onshore Morocco ("Certification").

The Certification, which will include a full technical review of the Tendrara project, is being conducted by RPS Energy Consultants Ltd ("RPS"). The Certification, which utilises the latest SPE Petroleum Resources Management System ("PRMS") approved definitions of Reserves and Resources, is a very important step towards concession application and a Final Investment Decision.

The preliminary results of the Certification (final results on the Tendrara area are expected to be available in early January 2017) provide volumetric estimates for the TAGI-1 and TAGI-2 reservoir units in the TE-5 Horst.

On 23 May 2017, the Company announced an internal preliminary mid case gross Gas Originally in Place ("GOIP") estimate for the TE-5 horst of 0.63 Tcf. 

Sound Energy is delighted to report that the preliminary results of the Certification validate this previous mid case GOIP (gross) estimate.   

Preliminary results of the RPS certification:

·      A mid case GOIP for the TE-5 horst alone of 0.65 Tcf

·      A 2C (mid case) recoverable, contingent resource for the TE-5 horst of 377 Bcf

The results of the Certification will be utilized for development planning and to advance development funding solutions, already under discussion.

The Certification was undertaken on an area of 250km², which equates to around 1% of the total Eastern Morocco permit area of approximately 23,500km². Planning for the Exploration drilling programme, announced on the 4 October 2017, continues in parallel with the development activity.  This programme is an important step in unlocking the Company's previously estimated unrisked GOIP potential across all the Eastern Moroccan acreage, of 17 Tcf mid case (31 Tcf upside case and 9 Tcf low case), as announced on the 1 February 2017.

The table below summarise the preliminary results of the Certification and present the discovered in-place plus Contingent Resources evaluated by RPS for the Tendrara TE-5 horst.
