Announcements by the Directorate General of Oil and Gas (MIGAS) for new Production Sharing Contracts (PSCs) in Indonesia has manifest a sense of urgency to evaluate potential acreage in the Makassar Straight. Hydrocarbon shows in the new Blocks are limited, but the geology of the Makassar Strait suggests that a petroleum system is actively charging reservoirs in the region. Confirmation of a working petroleum system however, is essential prior to acquiring or drilling this acreage. Such confirmation can be cost effectively derived, pre-drill, from seabed geochemical coring, heat-flow probe measurements and paleontologically dated seafloor cores.

Makassar Strait Study Area


TDI-Brooks Int’l Inc.
is negotiating with the Directorate General of Oil and Gas (MIGAS) of the Indonesian Department of Energy and Mineral Resources to conduct topical seabed studies to assess the presence and adequacy of the Petroleum System in the Makassar Strait. TDI-Brooks is pleased to offer the following non-exclusive programs. Acquisition is scheduled to commence in April 2002 using our research vessel R/V GeoExplorer. This vessel will be mobilizing for several projects in NW Australia from mid-December 2001.



The following programs are available for subscription either in total or by block:

Surface Geochemical Exploration (SGE) Study:
– Acquisition of approximately 150 seabed piston cores to locate and sample naturally occurring hydrocarbon seepage.
– Correlation of seepage occurrences with deep sub-surface tectono-stratigraphic patterns.
– Analysis of percolating hydrocarbons for correlation to probable source intervals at depth.
– Biomarker analysis for selected samples.Seabed Heat Flow Study:
– Acquisition of approximately 12 multi-thermistor probe measurements of the regional seabed to estimate basal heat flow.
– Acquisition of approximately 3 multi-thermistor probe measurement of at SGE core sites to estimate upward fluid movement.

Acoustic Profiling:
– Sub-bottom Chirp II acoustic profile records over all core and heat flow probe locations.

Select Paleontological Sampling:
– Acquisition of selected subcrop samples for paleontological analysis is available at additional costs/participant (TBD).

Pre-acquisition subscription cost per participant for SGE program: USD $185,000.
Estimated post-acquisition subscription cost per participant for SGE program: USD $235,000.
