Hydrocarbon Geochemistry Survey Data from WA-28-P Permit, 1990

October 22-28, 1990, a seismic survey collected 531 km of Direct Hydrocarbon Detection (DHD) data across 25 lines in the WA-28-P exploration permit area of the Dampier Sub-Basin, Australia. The data were acquired by the Marine Geoscience and Petroleum Geology Group (Australian Bureau Of Mineral Resources) in cooperation with Woodside Petroleum Pty Ltd. No significant hydrocarbon anomalies were detected, indicating well-sealed reservoirs in the surveyed region.

Use Cases

• Evaluate the effectiveness of Direct Hydrocarbon Detection (DHD) methods based on survey results over known accumulations.
• Analyze reservoir seal integrity based on the lack of detected anomalies despite traversing known oil and gas fields.
• Study background and minor hydrocarbon concentration variations based on reported ppm values at specific well locations.

Strengths

• Survey covers a specific geographic area (WA-28-P permit) and time period (October 22-28, 1990).
• Data acquisition involved 531 km of survey lines across 25 lines.
• Description includes specific quantitative observations, such as a THC increase from 16ppm to 22.8ppm at Montague 1.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic/temporal/source bias inherent to data_gov_au.
