Monitoring CO₂ Storage Integrity with InSAR: 2025 Safety – Redefining Compliance and Safety in Mining

Meta Description: Monitoring CO₂ Storage Integrity with InSAR for Compliance and Safety in Mining. Discover how this technology secures mining CCS and ensures regulatory compliance in 2025.

Introduction

As global efforts intensify to mitigate climate change, the focus on reducing atmospheric CO₂ levels has only grown. Carbon capture and storage (CCS) has emerged as a critical technology, helping sectors like mining reduce emissions by securely containing carbon dioxide underground.

However, the integrity of these storage sites is paramount. Even the smallest leakage or fault in the geological system can release greenhouse gases back into the atmosphere, risking operational compliance and public safety. It is here that Interferometric Synthetic Aperture Radar (InSAR) has gained prominence for its advanced, remote sensing capabilities.

This blog will explore how Monitoring CO₂ Storage Integrity with InSAR for Compliance and Safety is revolutionizing mining CCS by providing real-time, precise data for integrity, early warning for leakage, and continuous regulatory compliance—especially in 2025 and beyond.

Monitoring CO₂ Storage Integrity with InSAR for Compliance and Safety: The 2025 Imperative

Monitoring CO₂ Storage Integrity with InSAR for Compliance and Safety has become indispensable for mining in 2025. With CO₂ storage operations often located in depleted mines, saline aquifers, and other subsurface formations, the paramount challenge is ensuring these underground reservoirs remain impermeable.

When compressed CO₂ is injected underground, it can cause minor shifts in the surrounding rock strata or caprock. These changes—sometimes just a few millimeters—can be the first sign of increased reservoir pressure, fractures, or potential leakage. Detecting and responding to such subtle movements is now possible thanks to InSAR.

Enabled by modern satellite constellations and advanced processing algorithms, InSAR allows operators and regulators to detect ground deformations and failures early, reducing both environmental and operational risk.

Why CO₂ Storage Integrity in Mining Matters

Mining generates vast quantities of CO₂. With many operations located in regions with complex geology and extensive underground formations, ensuring storage integrity is both operationally challenging and environmentally essential.

Key reasons for focusing on storage integrity include:

• Preventing Leakage: Stop CO₂ from escaping into the atmosphere or seeping into groundwater and soil.
• Safety: Early warning of subsidence or structural hazards protects people and infrastructure.
• Regulatory Compliance: Compliance with environmental rules and eligibility for carbon credit schemes requires high-integrity storage.
• Reputation and Social License: Demonstrating compliance and safety builds public trust and supports continued operations.

Traditional monitoring methods—like borehole sensors, manual inspections, and ground-based seismic arrays—are limited in spatial coverage, often expensive, and sometimes miss subtle deformation patterns that signal warning.

Technology Basics: What is InSAR?

Interferometric Synthetic Aperture Radar (InSAR) is an advanced remote sensing technique that utilizes satellite radar signals to monitor ground surface displacements over time. It leverages differences in phase between successive radar images of the same area to map deformation patterns with precision down to just 1 millimeter.

The synthetic aperture radar (SAR) sensor on board satellites emits microwave signals to the Earth’s surface, which then bounce back and are recorded. By comparing successive images of a storage site, InSAR can detect ground level shifts caused by underground activities—including CO₂ injection, rising reservoir pressure, or even the opening of fractures and faults in geological formations.

Key Features of InSAR:

• High sensitivity for minor ground movements (detects as small as 1 millimeter).
• Wide-area surveillance—covers large mining areas and multiple storage sites simultaneously.
• Frequent revisit intervals allow for near-real-time monitoring.
• Non-invasive and does not require additional ground installation.
• Operates through clouds and day/night cycles, unlike optical satellites.

How InSAR Works for CO₂ Storage Monitoring

When CO₂ is injected into depleted mines or saline aquifers, tiny ground displacements may occur. InSAR monitoring detects and measures these deformations, enabling mining operators to:

1. Identify Early Ground Movement: Surface movement—even down to millimeters—can indicate pressure changes or faults forming in the subsurface.
2. Monitor Caprock Integrity: Subtle subsidence or uplift might signal fractures, leakage paths, or caprock failures.
3. Map Deformation Patterns: Systematically compare successive radar images to distinguish between safe and at-risk zones.
4. Integrate with Other Data: Combine with geological models and borehole sensors for all-round surveillance.

By monitoring ground deformation continuously, potential integrity breaches are detected early, allowing operators to respond proactively—adjusting injection rates, implementing repairs, or initiating evacuation if necessary.

Recent Advancements in InSAR Monitoring – 2025 and Beyond

The capability of Monitoring CO₂ Storage Integrity with InSAR for Compliance and Safety has accelerated in 2025 due to major advances in:

• Satellite Constellations: More satellites in orbit from both public and private actors mean more frequent, higher-resolution updates of storage sites.
• Data Processing Algorithms: Cloud-based and on-premises software use AI and machine learning to analyze huge volumes of raw radar data—delivering actionable, site-specific alerts for integrity failures and hazards.
• Pattern Recognition: Algorithms now identify fractures, faults, and leakage signs much earlier, even amidst noisy or complex geological backgrounds.
• System Integration: InSAR platforms now routinely combine radar imagery with ground-based sensors, environmental impact models, and resource planning dashboards.

Such advances ensure up-to-the-minute integrity monitoring of CO₂ storage sites—offering a quantum leap over traditional surveys and periodic manual checks.

Farmonaut, for example, leverages AI-driven tools and real-time intelligence to enable continuous asset tracking across mining and infrastructure sites globally.

Role of InSAR in Regulatory Compliance and Safety

Compliance with environmental regulations is non-negotiable for modern mining operators. Many countries and regions require CO₂ storage operators to demonstrate that injected carbon is being safely and permanently contained underground.

InSAR monitoring addresses key compliance questions:

• Is there any detectable deformation on the ground surface that may indicate leakage risk?
• Are reservoirs remaining impermeable over time?
• Is there evidence of structural failures or fractures in the storage system?
• Can the operator verify that storage integrity is being monitored continuously?

By providing continuous, high-sensitivity coverage (even over wide, remote mining areas), InSAR data helps operators secure permits, claim carbon credits, and satisfy third-party audits.

Early Leakage Detection and Data-Driven Risk Management

A leak or pressure spike, if undetected, could risk groundwater contamination, cause sudden ground subsidence (damaging roads, pipelines, or buildings), or jeopardize local ecosystems.

InSAR enables early detection of:

• Subtle surface displacements linked to underground leaks or migration paths
• Pressure build-ups in storage sites threatening caprock integrity
• Formation of new faults or fractures in underground rock

With this actionable intelligence, operators can swiftly implement mitigation plans—such as adjusting injection protocols, inserting sealants, or, if necessary, safely halting operations before catastrophic failure occurs.
