Sound Energy said its estimates for its second Tendara well are significantly higher than initial estimates.
The company previously announced it had drilled the TE-7 well to a total depth of 3,459metres.
The firm has now completed the work and performed an initial, unstimulated, open hole well test of the first 28% of the gross reservoir interval.
Sound Energy said it will now complete the planned mechanical stimulation and well test of the entire sub-horizontal section.
The post stimulation flow rate results are expected mid November.
