Sound Energy has completed its seismic shoot in eastern Morocco, revealing a new large Palaeozoic structure. This, the UK-listed minnow said, “could be the largest prospect within the entire basin”. As a result, the company said on August 21, this prospect could be tested with a third exploration well, TE-11.
Sound acquired 2,850 line km of 2D seismic under its programme, which was completed on budget and with no lost time incidents. As a result of this seismic, and basin modelling, Sound believes that the area’s gas charge comes from Devonian-age marine source rocks. The costs for the seismic were covered by Schlumberger, which has taken a stake in Sound’s Moroccan operations.
The company also said it had finalised the specific location for the TE-10 exploration well, which will target the North East Lakbir prospect. This will be drilled immediately after TE-9.
The TE-10 will target a high-impact TAGI structural stratigraphic play, with estimated mid-case volumes of 2.6 tcf (73.6 bcm) of gas originally in place, with an upside case of 5 tcf (141.6 bcm). This well will test both the TAGI section and the underlying Palaeozoic.
The prospect identified by the new seismic comes in addition to the Palaeozoic targeted in the TE-10. The new structure is to the northwest of the structural-stratigraphic play.
Sound announced the mobilisation of the 1,500 HP National 110 IE rig, owned by Saipem, to the TE-9 well pad, on the Tendrara licence, on August 13.
In June, the company announced a new basin model suggesting the existence of an oil play in its Anoual permit. This is another candidate for the TE-11 well. The model was based on a full tensor gravity gradiometry (FTG) survey and data from the TE-6, -7 and -8 wells.
