The Mass Spectrometer for Wellsite Gas Analysis.

Spec

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
