ConocoPhillips group makes Browse basin gas discovery

The ConocoPhillips-Karoon Gas Australia partnership has made a natural gas discovery with its latest Browse basin wildcat, Pharos-1, drilled in permit WA-398-P offshore Western Australia.

The group reported the presence of moveable hydrocarbons indicated by petrophysical log interpretation, formation pressure gradients, and downhole gas sampling.

Karoon’s assessment shows a 53-m gross gas interval with 34 m of net pay in the well, which was drilled to a total depth of 5,220 m.

Wireline logging operations are still under way; these will be followed by a full production test.

Pharos-1 is the sixth and final well in Phase 2 of the group’s Browse basin drilling campaign to evaluate the Greater Poseidon area.

Pharos prospect is 9 km northeast of Proteus-1 and was drilled as a further evaluation of the Proteus-Crown trend. The well targeted an extension of the Proteus discovery, which established good reservoir quality and condensate-bearing gas in the Montara formation.

Operator ConocoPhillips used the Transocean Legend semisubmersible for the Pharos well.

ConocoPhillips holds 60% interest and Karoon, 40%.
