Operational Update : Eastern Morocco

Sound Energy ("the Company"), the Moroccan focused upstream gas company, provides an update on its on-going exploration progamme.

TE-10 Well Test: Gas to Surface Pre Stimulation

The Company previously announced a discovery, and a planned stimulated well test, at TE-10, the second well in Sound Energy's current three well exploration programme in the Greater Tendrara area, onshore Morocco. The test programme involves rig-less re-entry of the TE-10 well in the TAGI reservoir, and both unstimulated and stimulated flow tests on multiple intervals. 

The Company confirms that the initial phase of the test programme - the unstimulated test - has now been largely completed, over a gross interval of 158m between measured depths ("MD") of 1932 and 2090 metres MD in the TAGI. Interpretation of these tests is continuing.

The Company is delighted to report that it has secured hydrocarbon gas to surface (C1 to C5 composition) from within the primary shallow zone, a section of which was perforated from 1932 to 1938 metres MD.  This has been achieved without stimulation or artificial lift. 

The next step in the operation will be to mechanically stimulate the most prospective zones, in order to seek to establish potentially commercial flow rates of gas.  As previously communicated, based on the Company's assessment of the reservoir section, a stimulated flow rate of approximately 1.5 mmscf/d to 2mmscf/d, is likely to be commercial (as a tie-back development to the TE-5 Horst existing discovery). 

Award of Environmental Impact Assessment ("EIA")

The Company is pleased to confirm the successful conclusion and award by the Moroccan authorities of an EIA for future drilling activities. The EIA  covers approximately 9,400 square kilometres in the northern region of the Greater Tendrara permit and the majority of the Anoual permit. The relatively large size of this EIA is designed to give the Company maximum flexibility in selection of future wells in the acreage including the forthcoming TE-11 exploration well and further future drilling locations.
