SANDBOX MODEL RESULT
The complexity of tectonic
history lead to the complex
structural configuration.
Structural restoration method is
very important to understand the
structural evolution.

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.
