Sounde Energy, the Moroccan focused upstream gas company, announced December 27 the preliminary results of intermediate wireline logs at TE-10, which indicate the presence of gas bearing sands in the TAGI.
James Parsons, Chief Executive Officer of Sound Energy, commented:
‘These positive initial results underscore our confidence in the exploration potential across the broader basin. We will now finalise the logging, drill to TD and then test the well to better understand the scale of the discovery and seek to confirm commercial flow rates.’
The TE-10 well is testing the North East Lakbir prospect in the Company’s Greater Tendrara permit. The Company is part way through its three well exploration programme in the Tendrara area designed to explore three geologically-independent plays and to establish the potential of the basin. TE-10, the second well in the programme, was designed to target both a material TAGI stratigraphic trap and a smaller TAGI structural closure in the Company’s Greater Tendrara permit. The well is located approx. 25 kms to the northeast of the recently awarded Tendrara production concession, which contains the TE-5 Horst discovery unlocked by Sound Energy in 2016-17.
The TE-10 well has, so far, been drilled to 2,098.5m total measured depth, penetrating the top of the TAGI sand sequence at a measured depth (‘MD’) of approx.1,892m.
Based on cuttings and the results of preliminary wireline interpretation, there is a potential gross reservoir interval from 1,899m MD to 2,009m MD. Gas shows greater than background levels were observed from 1,908m to approx. 2,030m MD and included a range of C1 to C5 hydrocarbons. Preliminary interpretation of the intermediate wireline log data currently acquired indicates thinly bedded gas bearing intervals within the gross section, with initial estimates of net pay (based on various conservative assumptions) of up to 10.5m and an average porosity of 8% (a similar porosity to previous productive wells in the Company’s existing discovery). Wireline logging is ongoing, including the planned acquisition of side wall cores and the use of a modular formation dynamics tester system (MDT) to gather samples (rock and fluid) and pressure data which will assist in potentially increasing the net pay estimate.
After completion of the intermediate logging programme, the Company plans to drill the remaining TAGI section to total depth just beneath the Hercynian Unconformity and then perform a well test, including possible mechanical stimulation. The Company will also initiate seismic analysis to establish the Company’s internal estimated gas resources of the structural closure and the upside potential of the North East Lakbir stratigraphic trap.
Ground works for the drilling of TE-11, the third well in the exploration programme, are expected to commence after the TE-10 well test.
The Company remains well funded with unaudited cash balances as at 14 December 2018 of US$27 million.
