Shipwreck Trough Geological Carbon Sequestration Plays from Basin Modelling

A regional geological carbon storage screening study for the Shipwreck Trough offshore Otway Basin. The study employed 2D basin modelling along three seismic transects, integrating seismic interpretation, well data, and geochemical analyses to evaluate storage capacity and containment risks. It was published by Geoscience Australia Data.

Use Cases

• Evaluate CO2 storage capacity based on identified aquifer porosity and seal thickness.
• Assess containment risks based on analysis of fault reactivation and pressure regimes.
• Compare the suitability of different geological plays (Waarre-Belfast, Thylacine-Belfast, Nullawarre-Belfast) for regional-scale storage.
• Model hydrodynamic conditions based on well data for pressure, temperature, and water geochemistry.

Strengths

• Identifies specific promising plays (Waarre-Belfast/Skull Creek) with favorable porosities of 18–23%.
• Quantifies seal performance, predicting CO2 column height capacities exceeding 300 meters in favorable locations.
• Integrates multiple data sources including seismic interpretation, well data, and geochemical analyses.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect geographic bias inherent to the specific offshore Otway Basin study area.
