Westport ARMIS™: Methane Isotopes at the Speed of Light

Intertek provides Petroleum Wellsite Solutions in Real Time:

Intertek Westport’s Automated Real-time Methane Isotope System (ARMIS™) provides continuous real-time carbon and deuterium isotope measurement on methane in mudgas at the wellsite. The ARMIS device provides concentration data for methane and ethane. The isotope data ARMIS™ provides in seconds takes 4-6 weeks to obtain by conventional laboratory analysis. The methane isotope data are critical for wellsite evaluation of hydrocarbon shows and real-time decision making.

Hydrocarbon Show Assessment:

ARMIS™ data provide a basis for instant evaluation of hydrocarbon shows including:

• Biogenic vs. thermogenic origin
• Depth of thermogenic source
• Proportion thermogenic gas in mixtures
• Association of gas with hydrocarbon liquids

Real-time obtained information provides a sound basis for making drilling and testing decisions. Without ARMIS™, evaluations require weeks and are not available for wellsite decisions.

Extended Gas Evaluation:

Evaluation of ARMIS™ data with similar data from other wells provides rapid assessment of well and reservoir parameters including:

• Target interval penetration
• Stratigraphic correlation between wells
• Preliminary reservoir continuity assessment
• Real-time horizontal drilling position

Wellsite Sampling:

ARMIS™ can be integrated with Westport’s automated mudgas sampling system to provide automated, intelligent sampling of mudgas based on customer’s criteria. The system monitors the mudgas and recognizes gas to be sampled while skipping unimportant shows, such as biogenic gas. The containers are easily shipped and analyzed in detail at Westport.

Automated Real-time Methane Isotope Measurement System (ARMIS™):

• Provides real-time carbon and deuterium isotope analysis of methane in mudgas
• Provides real-time concentrations of methane and ethane in mudgas
• Operates continuously during drilling
• Provides data for immediate evaluation of shows for testing, well correlation, reservoir continuity, etc.

Engineered for Wellsite Operation:

ARMIS™ employs state-of-the-art laser spectroscopy in a rugged unit specifically engineered to operate under wellsite conditions. The automated system fits in an electronics rack and requires only electric power and a hydrocarbon stream to analyze. The data are available in real-time with basic interpretation performed by the software. More complex interpretation is available via remote data evaluation by Westport experts.
