GasClam Borehole Gas Monitor


The World’s first in-situ borehole gas monitor!

GasClam can be used below ground for up to three months to measure a variety of gases, with temperature, barometric and borehole pressure giving a true long term profile for the first time! It’s truly the definitive method of measurement for most below ground applications.

Key features:

  Easy installation in a secure 50mm or 2 inch borehole
  Three months continuous un-manned data collection
  Methane (CH4), oxygen (O2) and carbon dioxide (C02)
  Temperature, borehole and atmospheric pressure
  Optional CO or VOC plus water depth
  Runs on two standard D-cell batteries
  Explosion Proof
  Programmable borehole venting

TRADITIONAL METHODS

Using portable gas detection instruments to spot check boreholes from time to time is fraught with potential issues. Considerable published material exists that question whether the traditional method of collecting gas-data from boreholes is at all adequate.

The use of the numerous guidance notes from the legislators and enforcers would seem to indicate they too think the current methods are flawed. To evaluate boreholes effectively detailed and frequent measurements are required, particularly when events occur e.g. such as when the barometric pressure falls. Data collected on in periodic spot check basis does not give a complete picture so decisions are made reliant on historic set points rather than real trend information on the borehole being monitored.

Current issues:

1. Spot check data only available.
2. Major gas events are often missed.
3. Lack of real data leads to misleading conclusions.
4. Frequent expensive site visits to take only spot readings.
5. Independent borehole profiles are just not available.

All these uncertainties led Salamander to develop the unique and patent pending GasClam which is designed as the definitive solution.

Data Sheet
Manual

THE GASCLAM SOLUTION FOR:-

LANDFILL - Gas generation and migration are subject to operational control on landfill sites. GasClam data can be used as the feedback to ensure control is effective particularly where Biogas is used and greenhousegas emission levels measured. Below ground fires as a result of spontaneous combustion can be monitored using the optional CO sensor fitted to the GasClam. An accurate assessment can be made of severity and the extent of the landfill effected this is essential for full risk assessment.

BROWNFIELD AND DISUSED COAL MINES - With GasClam, periods of continuous monitoring can be practically and economically incorporated into site Investigations. With full data available, boreholes can be profiled and the optimum monitoring programme ascertained. A time saving tool whilst reducing risks at the same time. Where sites show significant gas present these can be long term monitored to ensure the risks are fully understood before remedial actions are recommended.

PETROLEUM STORAGE AND FILLING STATIONS - Below ground storage of petroleum is currently the norm when associated with filling stations. As tanks age and connections corrode the repair of the inevitable leak represents a significant environmental hazard. Used in some well placed boreholes the GasClam with optional VOC sensor fitted can monitor sites to ensure leakage is kept to a minimum or even indicate where repair may be necessary. After repairs or clean-up the GasClam can be used to validate the result for the local authorities or regulatory bodies. Long-term deployment produces data that can be used for management of operations and can be incorporated into risk assessments for storage facilities.

This method of leak detection is sure and certain.

CARBON CAPTURE AND STORAGE - With carbon trading a reality, carbon offsetting and storage has become a major commercial enterprise. However, it is limited at present because of disagreements and difficulties in verification of longevity of storage. The GasClam with its ability to continuously measure and the potential to use this data to calculate gas fluxes – is likely to be indispensible during the growth of this new business area.
