LaserSense-ML™: Process Gas Analyzer for Mud-Logging
Block Engineering’s LaserSense-ML is a hydrocarbon (C1-C5) gas analyzer for mud-logging and related oil and gas applications. The Quantum Cascade Laser-based system measures hydrocarbon gases from ppm level to percent level, allowing for both sensitive detection and a large dynamic measurement range.
In mud-logging gas analysis, speed, accuracy, and uptime are critical. Drilling speeds have increased to the point that current Gas Chromatography (CG) analyses of the evolved gases have become a bottleneck for geologists. A driller could potentially miss an entire reservoir because the probing speed is now significantly faster than the analysis time.
The LaserSense-ML provides a clear alternative to traditional GC and GC/MS solutions, allowing for much quicker readings (10 seconds or faster), no costly consumables, and very little maintenance. When deployed directly at an oil drilling site, a QCL-based system allows critical decisions to be made faster and more reliably than ever before.
The LaserSense-ML is ruggedized such that measurements are not affected by vibration, allowing the unit to operate at 100% duty cycle. A pump and pressure sensor can be integrated to provide continuous monitoring in under- and over-pressure environments, and the entire gas handling path can be heated to reduce condensation of heavier hydrocarbons and water.
Lasers are eye-safe, and the unit is available in NEMA 4x and explosion-proof enclosures.
Advantages of the LaserSense-ML over Traditional GC
- Accurate detection of C1 through C5, including C4 and C5 Isomers
- Requires no carrier gases
- A truly continuous measurement (not a batch measurement)
- Fast response time of 10 seconds
- No consumables
- Small footprint
- Environmental/explosion proof packaging available
