Abstract
ABSTRACT: Characterizing the Hydrocarbon Potential of a Paleo Stepped Slope Setting, Offshore Sabah
Talisman Energy USA Inc.
The exploration effort currently underway in Talisman Malaysia
on blocks in Eastern Malaysia, offshore Sabah, Borneo include
establishing a new play in this area. Historically, previous drilling in
the blocks has primarily tested the topset shelfal play system. Through
new 3D seismic volumes, reprocessed 2D lines, remaining potential
of the blocks are being identified. Initial evaluation of the Saracen 3D
seismic volume on the north eastern portion of block SB309 identified
the potential of a deep water reservoir play in the underexplored
deeper part of the stratigraphic section. Investigation of the Stage 4A
and 4B stratigraphy in the Saracen 3D seismic shows a number of
basins along a stepped slope profile that could hold turbiditic channel
and distributary systems. Seismic 
attribute
extractions of the fill of
these basins indicate patterns consistent with sediment distribution
from turbidites and other sediment gravity flows. Mitigation of the
main risks of reservoir quality and updip seal include detailed analysis
of the seismic data as well as incorporating global analogues
