MEO Australia Limited (ASX: MEO; OTCQX: MEOAY) provides the following update in relation to Heron South-1 being drilled in NT/P68, operated by Eni Australia Ltd (Eni).
Since the last report the first of the two planned production test programs has been completed.
Drill Stem Test (DST) #1 of the Elang-Plover reservoir was performed through a 114mm (4½") slotted liner. The flow rate was too low to be measured accurately, however gas was flared at the surface. Gas composition was analysed using a gas chromatograph and assessed to contain approximately 35% CO2.
DST#1 has confirmed gas in the Elang-Plover reservoir however the reservoir permeability appears very low.
Eni is currently preparing to undertake the second production test over the Frigate formation. The Frigate formation will be perforated using tubing conveyed perforating (TCP) guns through the cemented 178mm (7") liner.
The information from both DST’s together with the observations made whilst drilling the well will be reviewed to determine the forward plans for the Heron gas discovery.
In accordance with pre-drilling plans, the well will be plugged and abandoned at the conclusion of production testing.
Eni has 60 days from the completion date of the well to elect to drill a second Heron well to complete the farm-in to the Heron gas discovery.
