MEO confirms Heron-2 gas shows

CORE samples have confirmed that the Heron-2 well, in the Timor Sea, has encountered the same gas-bearing zones seen in the Darwin Formation as the original discovery well, according to operator MEO Australia, an LNG hopeful.

In addition, preliminary analysis of log suites also indicated the Facies 2 zone to be gas-bearing in Heron-2, MEO said.

But MEO and partner Petrofac Energy Developments have yet to decide whether to flow-test these zones.

“Until the hydrocarbons are recovered and analysed, MEO is unable to confirm gas quality or that a recoverable resource is present in Epenarra,” the company said.

“Production testing of Epenarra can only be undertaken after the drilling – and if warranted flow testing – of the underlying Heron North structure.”

MEO said the West Atlas jack-up rig was currently running 9 5/8-inch casing to the 3360m section depth, after which drilling will restart in an 8 ½-inch hole into the Heron North/Plover formation.

Following Heron-2, the rig will move to the Heron-3 well, aimed at testing the commercial viability of hydrocarbons in a 500-metre horizontal section through the Darwin Formation, the reservoir section of the large Epenarra structure.

The Heron-2 and Heron-3 wells are targeting the two gas-bearing horizons in the Darwin formation and the deeper Elang-Plover Formation, observed in the Heron-1 well.

The two-well campaign will be funded 75% by MEO and 25% by farminee Petrofac, in return for a 10% stake in the permit.

Petrofac has an option to increase this stake to 15% by funding 37.5% of the well costs.
