Studi Potensi Minyak Dangkal dengan Pendekatan Metode Statistik Berdasar Data Geologi Permukaan Di Cekungan Banyumas
Abstract: Banyumas basin is
part of South Java Fore Arc Basin. Tectonically, Banyumas basin also included
in South Central Java Region, where the main structure are trending Northwest –
Southeast and Northeast – Southwest. Stratigraphically, the formation sequence
from the oldest to the youngest are : Gabon Formation, Pemali Formation,
Kalipucang Formation, Rambatan Formation, Halang Formation, Tapak Formation and
Alluvium & Volcanic deposits. Banyumas basin and surrounding area have
several oil and gas seep. This seep indicating there are mature source rock
that had been migrate to the surface. The factor required for existing of
hydrocarbon is called petroleum systems, and the factor are : mature source rock,
reservoir rock, cap rock/seal rock, trap and proper timing of migration. The
study of shallow oil potential is a preliminary step to find the suitable
exploration concept for Banyumas basin. This step is used after the discovery
of shallow oil accidentally in about 90 meters depth in Tipar Village,
Ajibarang sub-district. This study using the surface geological data and
secondary data available and also scientific paper, related to Banyumas basin.
Statistical method approaching is using the assumption of minimum probability
(P10) to estimate the reserves potential of shallow oil that probably exist in
Banyumas basin, and the result is the reserves potential about 2,181,937
barrels oil.
