Shine a light on geothermal potential with low cost seismic solutions

Seismic data plays a crucial role in regional scouting for potential geothermal sites. By utilising 2D or 3D seismic data, it allows for the identification and grading of prospective geothermal locations. This process involves:

1. Identifying target horizons and structural elements: Analysing seismic data to assess the depth to the target horizon and key structural elements, such as faulting and fracturing, ensuring the presence of a viable geothermal system.
2. Determining aquifer volume and depth: Accurately identifying the volume and depth of aquifers, which is essential for estimating water temperatures. These temperature estimates are critical for designing efficient and effective geothermal facilities.

By providing detailed subsurface information, seismic technology significantly enhances the accuracy and efficiency of geothermal site selection and project planning.

De-risk pre-drill decision-making and assure compliance with high-definition seismic data:

1. Demonstrate safety and risk management: Provide regulators and stakeholders with detailed evidence that potential risks have been identified and a comprehensive mitigation plan is in place, ensuring the project's safety and regulatory compliance.
2. Optimise well placement: Accurately identify faults and optimise well placement to avoid potential loss zones, maximizing well recovery and reducing the overall well count, thus improving cost efficiency
3. Understand permeability networks: Gain a detailed understanding of permeability networks, which is crucial for achieving optimal flow rates and effective recharge of the aquifer, leading to sustainable and efficient geothermal energy production

Subsurface monitoring is essential for the ongoing management of geothermal wells, particularly during production. This involves:

1. Ensuring safety and compliance: Implementing a long-term seismic monitoring plan to verify that the geothermal project aligns with initial expectations and operates safely. Continuous monitoring helps in identifying any deviations or potential risks early on.
2. Adapting to regulatory and stakeholder requirements: Depending on local regulations and stakeholder needs, varying levels of seismic monitoring may be necessary. This can range from deploying several seismic receivers to hundreds, enabling precise detection and location of subsurface seismic activity.
