Sound Energy, the African and European focused upstream gas company, is pleased to confirm a successful extended well test at TE-7, the Company's second well at the Tendrara licence (onshore Morocco).
The Company has flowed just under 1.0 Bscf from TE-7 over a period of 56 days continuous flow and has now started a final pressure build-up phase. The overall extended test results are consistent with the Company's estimates and confirm the good deliverability of the TAGI reservoir, the horizontal well concept and the Company's view of the significant potential of the field.
Throughout the test the flow rate was limited by the Company at a maximum 40% drawdown to preserve completion integrity. The average constrained flow rates over the course of the extended well test were as follows:
Choke Size Average Rate
44/64 inch 28 mmscfd
36/64 inch 22 mmscfd
28/64 inch 15 mmscfd
The Company confirms that, as expected, no formation water was produced during the test and no indication of barriers were detected - confirming a significant connected volume. The pressure gauges at TE-5 and TE-6 will be monitored over the next month to further confirm the physical connectivity of the reservoir.
The results of the extended well test will now be analysed and utilized to finalise field development planning.
As announced on 15 December 2016, the reservoir pressure at TE-7 has been confirmed to correlate with the gas gradient recorded at all previous wells on the structure.
