Wireline logging at the ConocoPhillips operated Poseidon-1 exploration well off Western Australia has shored up the presence of a gas column in the target Middle Jurassic Plover formation.
‘During the wireline logging a tool became stuck and partner Karoon Gas said that fishing operations are being carried out on the tool before completing logging and conducting production testing designed at flowing gas from the reservoir and determining reservoir characteristics. Three gross sand intervals have been penetrated, with thicknesses of 10 metres, 67 metres and 139 metres. The wireline logging operations have acquired reservoir pressure data across a 56 metre interval within the upper part of the lower 139 metre gross sand interval which confirms the existence of a gas column before the tool became stuck, said Karoon. Poseidon-1 is the first of a six-well drilling program being carried out by the operator ConocoPhillips and Karoon Gas in Browse basin permits WA-314-P, WA-315-P and WA-398-P.
