Analyzers for Oil and Gas Markets

Block Engineering's infrared laser-based analyzers offer fast, safe, affordable analysis of hydrocarbons and related gases. Unlike traditional gas chromatographs (GCs), our QCL instruments require no consumables or carrier gases, require no calibration, and afford significant cost savings with no maintenance and calibration labor. In contrast to GCs, analysis time is extremely rapid (less than 10 seconds) and readings are highly sensitive.

Block's systems are used by oil and gas well drillers to more efficiently find the deposits they are seeking. For example, in mudlogging applications our analyzers provide for accurate detection of C1-C5 hydrocarbons, including C4 and C5 isomers, enabling geoscientists in near real time to compute hydrocarbon ratios to identify important geological formations and strata.

We also offer analyzers that measure BTU, calorific value, and Wobbe index values with extreme precision while also speciating the individual hydrocarbons. In addition, Block's spectrometers can monitor perimeters, detecting chemical emission leaks from distances of up to 500 meters in seconds.

Mudlogging: Block's LaserSense-ML is a compact system designed for mudlogging applications. The LaserSense-ML is available in rack mount and pelican case configurations. With the ability to detect C1-C5 gases, plus isomers, in ppm to percent ranges, the LaserSense-ML offers a fast (10 second readouts), low-maintenance, accurate, and safer alternative to GC technology. Importantly, the fast readout enables geoscientists to more precisely map the drilling geology and avoid missed shows. Learn more

BTU/Wobbe Analysis: LaserSense-CV is a calorific value analyzer that measures the BTU and Wobbe Index of natural gas streams. Based around a widely tunable mid-infrared laser, the LaserSense-CV is far more sensitive and accurate than near-IR analyzers, lower maintenance and faster than a GC, and provides for speciation in contrast to residual O2 measurement analyzers and inferential/physical properties analyzers.

For further technical information, you are also invited to read our detailed application note:

Real Time Measurement of BTU, Calorific Value, and Wobbe Index including Hydrocarbon Speciation (Application Note AN-N06-01): Block Engineering's LaserSense-CV provides precise, continuous measurement of CV, BTU, and Wobbe Index. In this application note, we detail the differences between Gas Chromatography, Mass Spectrometry, and Quantum Cascade Laser techniques in the full analysis of natural gas.

Emissions Detection: Block's LaserWarn system is an open-path chemical detector that can be used for fugitive emissions monitoring, or any other application that requires rapid identification of gases. The eye-safe laser allows for extreme sensitivity in the ppm range. The system can be used in both indoor and outdoor applications. Learn more
