| Summary: | Biogenic gas is an alternative energy in the future which is not optimally explored yet. Discovery of
biogenic gas found in offshore Madura in the Madura Straight even in Northern Madura.
Characteristic of biogenic gas source, which is different with usual hydrocarbon development
process will give a big new exploration opportunity in another area of Indonesia. Another reason of
it, because the biogenic gas develop in shallow burial deposit (less than 1000m). So in the near
future it could be explore in the top priority.
The research area geologically is part of the back-arc basin system with tectonostratigrafically
started from rifting phase which is deposited Palaeogene sediments (Ngimbang Formation, Kujung
III,II Formation), followed by sagging phase which is deposited Neogene sediments Kujung I
Formation, Tuban Formation, OK Formation), ended by compression tectonic phase which is
produce several litostratigraphy with different naming as Wonocolo Formation., Cepu Formation,
Tawun Formation, Ngrayong Formation, Mundu Formation, Paciran Formation, and Lidah
Formation). Geological Structure in this area relatively NE-SW, E-W (associated with left strike
slip fault from RMKS major fault)
Result of the research showing a different of sedimentation deposit history, although locally will be
affected to the gas type which is trapped. This issue founded on the OGX structure as the producer
of mixed gas (biogenic and thermogenic gas). In the MLX structure only produce a biogenic gas.
Biogenic gas is predicted mainly from Plio-plistosen formation age (Equivalent of Cepu and Mundu
Formation), and the thermogenic hydrocarbon source come from older formation (Equivalent to
Kujung Formation.)
Application of biogenic gas modelling will be easier if the paleo-geographic, sedimentation system
and petroleum system of the area will be explore combined with the general condition of biogenic
gas generation. |
