GHG & Surface Casing Vent Measurement

The Hawk Vent Gas Meter is designed to measure and digitally log low flow vent gas, such as methane, with high accuracy. Typical applications are surface casing vent, compressor seals, pneumatic control gas usage, and any vent gas where high accuracy measurement and audit trails are required. This is no lab grade toy. It is designed to be used unattended in the field where vent gas is not always clean and field conditions can be muddy.

Light weight, portable, hazardous location approved, designed and built in Canada for Canadian conditions. The Hawk is trusted by Industry, Governments and Academia across North America to provide accurate logged vent flow field data.

Thermal Surface Casing Vent Integrity Service

The Hawk SGA ( Steam Gas Analyzer ) is designed to measure and log steam and other gas from SAGD well surface casing leaks. Using a high performance radiator and cooling tower the SGA will knock off the steam and weigh it to measure the mass flow rate. The remaining gas flow rate can then be measured and a sampled for further analysis.

If H2S is detected a on board Cadmium Acetate bubble test can be preformed to determine if the H2S is biogenic or from a downhole formation which would indicated a well integrity issue..
