Coal Seam & Shale Gas
GasClam® enables continuous monitoring of active and non-active coal seam gas (coal bed methane) and shale gas mines.
The GasClam® collects continuous ground gas, water table and barometric pressure data, which supports and facilitates:
- A best practice approach to ground gas migration monitoring and reporting based on continuous and extensive site data
- Improved risk management and understanding of site conditions
- Early warning of ground gas migration issues
- Proactive site monitoring for fugitive emissions enabling transparent reporting to government and the public
- Demonstration of regulatory compliance
GasClam® is optimally deployed to characterise background gas levels during resource pre-drilling, as an ongoing continuous monitoring regime during site operation and, ideally, as a permanent post-operation installation.
Installing GasClams® in monitoring wells prior to drilling establishes the background concentration of ground gases, such as methane and carbon dioxide. This provides unique benchmarking data for impact assessments and ground gas level comparisons during the mining life-cycle.
The use of GasClams® have been investigated to commercially capture more comprehensive data sets around well programs, ensuring drilling programs and their interpretation is more targeted and efficient for relevant stakeholders.
GasClam® is battery powered for stand-alone site perimeter deployment, fits in a 50mm borehole and headwork for site security. The telemetry incorporated in the device facilitates remote access, setting of alerts and data upload.
GasClam® currently has a wide range of applications where continuous gas monitoring is advantageous including:
- Greenhouse and fugitive gas emission monitoring
- Leakage around solvent storage
- Petrol stations (VOC monitoring)
- Carbon dioxide sequestration
- Below-ground carbon capture and storage
- Refineries and long-term chemical pollution
The continuous ground gas data collected using the GasClam® provides landowners, developers and consultants with a detailed understanding of the ground gas regime on their sites.
Sites that show significant gas emissions can be monitored over the long-term to ensure risks are fully understood before and after remedial action is undertaken.
This detailed understanding can be used to:
- Design effective remediation measures that reduce risk to future site users
- Ensure timely discharge of planning conditions
- Reduce overall remediation costs
GasClam® provides in-situ continuous monitoring of ground gas on landfill sites, typically utilising existing (50mm) boreholes.
GasClam® monitors a wide range of ground gas parameters applicable to landfill sites such as:
- Carbon dioxide
- Carbon monoxide
- Hydrogen sulphide
- Volatile organic compounds
In addition, the GasClam® continuously monitors atmospheric pressure and temperature with the option of borehole water level.
Continuous monitoring with GasClam® enables site operators to:
- Make accurate risk assessments, based upon long-term data, linking ground gas information with environmental drivers such as barometric pressure
- Complete asset characterisation as opposed to the incomplete and misleading data sets provided by spot sampling
- Provide comprehensive asset reports to regulators
- Design and implement effective site management strategies
GasClam® is battery powered for stand-alone site deployment, and is telemetry enabled to allow remote operation, setting of alerts and data upload.
