The Mass Spectrometer for Wellsite Gas Analysis.
Spec
Mud-gas analysis is the analysis of formation fluids entrained in the drilling mud while drilling. This is a key and cost-effective piece of information for formation evaluation.
Spec is a mass spectrometer specifically designed for wellsite mud-gas analysis in real-time. Spec is a fully automated continuous-flow gas analyzer. It collects comprehensive gas data and correlates it with drilling parameters received over WITS to create a real-time depth profile. It’s easy setup, standalone and robust design, and minimal oversight requirements make it the ideal choice for gas analysis.
Applications
· Exploration, Development, and Production
· Conventional and unconventional resources
· Petroleum type and quality, Geochemical fingerprinting

Capabilities
· Organic species: Total gas, C1-C10 hydrocarbons; Distinguishes alkanes, cycloalkanes, and aromatics; BTEX compounds and water-soluble organic acids: Benzene, toluene, ethylbenzene, xylene, acetic acid; Standard gas ratios: Pixler, wetness, balance, character
· Inorganic species: Hydrogen, helium, carbon dioxide, nitrogen, oxygen, argon; Sulfur species: SO/SO2, COS, CS2. H2S with external sensor.
· Compatible with oil-based mud (OBM), water-based mud (WBM), and air drilling; Distinguishes formation gas from mud additives.
· No chromatographic separation required.
· No carrier gases needed, no combustion during measurement – reduces costs and improves safety. Also eliminates carrier gas and HC/CO2 interference.
· No calibration gases needed. Semiquantitative calibration under atmospheric nitrogen. Minimal drift over months.
· Works with various types of gas extractors, including nitrogen purged. Evaluates extractor and sample line performance.
· Continuous self-diagnostics with visual and email/text alerts. Remote monitoring and operation over internet. Unmanned operation possible.
