Eastern Morocco: Aerial Gradiometry Results

Sound Energy, the African and European focussed upstream gas company, is pleased to announce completion of the Airborne Full Tensor Gravity Gradiometry (FTG) and magnetic survey acquisition in Eastern Morocco.

The survey team, provided by AustinBridgeporth, flew a total of 26,700 survey line kilometres, across a total area of 22,800 square kilometres over the Tendrara, Matarka and Anoual licences in just less than twelve weeks. The survey, together with the new 2D seismic programme which is now underway, was commissioned to develop a better understanding of the subsurface structure and sedimentary succession.

The Company confirms receipt of a preliminary high resolution FTG and magnetic dataset, delivered on schedule and to budget, with highly encouraging results. Critically, these results include the delineation of previously unrecognised subsurface features and a clearer view of the deeper structure across the three licences. The preliminary data provides a far more detailed view of a deep, thick Paleozoic basin extending over the three permit areas, bounded by a series of NE-SW and NNE-SSW faults. The NNE-SSW fault trend is coincident with the Paleozoic anticline identified on 3D seismic beneath the TE-5 Horst (the possible third well location in the 2018 exploration programme). Other similar fault trends may indicate further Paleozoic potential. Following further data processing, likely mid-December, the Company expects to have an improved understanding of the exploration potential of the licence areas.
