Over a 56 day period of continuous flow the well has yielded just under 1bn cubic feet of gas, the company said.
That figure is made all the more impressive given that the gas flow was constrained in test conditions, at a maximum of 40% drawdown, in order to protect the integrity of the well completion to date. Gas flow averaged 28mln cubic feet per day whilst it flowed on a 44/64 inch choke, 22mln cubic feet under 36/64 inch choke and 15mln on 28/64 inch.
Sound Energy told investors that no formation water was produced during testing – which is what the company expected – and there were no indications of barriers.
It says that the results confirm a “significant connected volume” of gas is present at Tendrara.
“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,” Sound Energy said in a statement.
“The results of the extended well test will now be analysed and utilized to finalise field development planning.”
At the same time, Sound Energy is now preparing the next well at Tendrara.
The TE-8 well will be a ‘step out’ appraisal that aims to confirm the continuation of the large gas project some 12 kilometres to the northeast of the TE-7 well site.
This morning the company confirmed that civil works are now underway at the TE-8 well site and it expects drilling work to begin in February.
