The complexity of tectonic

history lead to the complex

structural configuration.

Structural restoration method is

very important to understand the

Banda Arc is a unique places for hydrocarbon

exploration with its complexity of geological condition

Eastern Indonesia “A big risk with a big gain…”

INPEX has a long history of exploration commitment in

Indonesia with its successful discovery in ABADI Gas

Field.

Back to basic geology and advance geosciences

method play as the main role to understand the Banda

Arc geology to unlock the hydrocarbon potential.
