2015 Makassar Strait Program
In 2015, EMGS will acquire 2 surveys in open blocks in
Makassar Strait, Indonesia. The OTI survey will be 1,250
km2 and ex-Papalang survey will be 1,200 km2 of full
azimuth 3D CSEM data using a 2.5 x 2.5 km receiver grid
to simultaneously acquire both inline and azimuthal data.
Recent reprocessing of 2D CSEM lines revealed several
untested anomalies and the integrated interpretation
of the newly acquired 3D CSEM and seismic data will
improve volume estimation and reduce drilling risk.
Prospectivity
The Kutei Basin is the most prolific petroleum basin in
Indonesia and the significant gas discoveries of Gehem
and Ranggas are just East of the OTI multi-client survey
area.
Deepwater exploration in the area has focused on
Pliocene and Miocene age reservoirs of coarse-grained
turbidities in slope channels and basin floor fan deposits.
However, basin floor fans can be difficult to map using
seismic data alone despite being associated with seismic
amplitude events. If these deposits are highly saturated
with commercial volumes of hydrocarbons, they would be
resistive anomalies.
Recent reprocessing of other CSEM data in the area
reveals several untested anomalies.
OTI survey
The Hiu Aman-01 well encountered 13-meters pay
approximately 2100 meters below mud line. Recently
reprocessed 2D CSEM data acquired over the well
indicates a deeper resistive anomaly below the well
coincident with a faulted structure. The survey will image
this interesting feature and provide valuable insight into
seal and charge risking along and can provide volume
estimations of additional leads.
Ex-Papalang survey
The Pananda-1 well situated 40 Km South-East of the
Gehem field, encountered a 24 m of gas interval in the
Middle Miocene section which confirmed the presence
of hydrocarbon in previously untested Mid-Miocene
turbidite play. With several other anomalies defined by
2D CSEM lines, the survey will help to create better
exploration outcomes with improved constraint on
Probability of success (PoS) and Volumetrics.
Deliverables include:
• Unconstrained 3D CSEM inversion data delivered
in SEG-Y
- Vertical and Horizontal Resistivity
•Anisotropy
• Raw data available upon request.
