Sound Energy PLC (LON:SOU) has announced that the TE-10 well, in Morocco, has higher exposure to net gas pay than previously estimated and, at the same time, has detailed the well is host to a significant amount of gas resources.
The company, in a statement, revealed that it had commissioned independent consultant ERCE which - using core samples and well log data – provide the basis of a new estimate that the TE-10 has 15.4 metres of net pay, up from 10.5 metres.
In the mid-case estimate, the well is viewed as having 13.1 metres of pay, while the low-case estimate put pay at 9.5 metres.

Sound also estimates that the North East Lakbir structural-stratigraphic closure, which is a feature in TE-10, has some 1.43 trillion cubic feet of gas originally in place (GOIP).
The upside case is stated at 3.4 trillion cubic feet, while the low case is made at 584bn cubic feet.
It cautioned, however, that a successful well test is always required to confirm reservoir deliverability and commerciality.
Plans are already in place for a test programme, due to get underway next month.
"We set out last year to deliver an ambitious three well exploration programme to further unlock the Tendrara Basin and our second well (TE-10) is a discovery,” said James Parsons, Sound Energy chief executive.
“Following our initial post drill technical analysis, we are delighted to materially upgrade our net pay and provide confirmation of the multi Tcf potential of this well.
“We now look forward to addressing reservoir deliverability and hence commerciality with the well test."
The test programme will start in mid-March with the initial tests measuring a series of unstimulated flow rates from multiple intervals to establish the presence of deepest moveable gas.
Subsequently, the plan is to conduct a number of stimulated production flow tests in late March.
