On-site real-time isotope analysis of mud gases on oil and gas exploration drill rigs using
the classic GC C IRMS method.
Traditional Stable Isotope Mass Spectrometers (SIRMS) are considered to be complicated, costly, cumbersome instruments. Their combination of bulk and fragility means that they’re only able to differentiate elements by their mass to charge ratio (m/z) normally operated from large regional lab facilities. Samples have to be brought from their origins to the laboratory for measurement. This is a slow expensive process which causes delay in data acquisition.
Thankfully, there is now a real alternative – the revolutionary new Isologger from Compact Science Systems. 19” rack mounting, remotely operated, transportable, durable, versatile, cost-efficient and ergonomic, the Isologger makes on-site real-time isotope analysis of mud gases possible. Put simply, it’s the most compact and rugged IRMS (Isotope Ratio Mass Spectrometer) in the entire solar system.
Here at Compact Science Systems, we’ve always believed in aiming high. So much so that we were the first company to put a SIRMS to extra-terrestrial use. This, in turn, makes the Isologger MS capable of performing MGIL in the most extreme of conditions.
Our machine was deployed in outer space on the Mars Express in 2003.
Needless to say, it had to be compact, sensitive and extremely robust – characteristics we’ve built into every machine we’ve made since, including the Isologger MS.
The Isologger MS makes MGIL possible pretty much anywhere on the planet – even on your drill site. Low power demands, frugal gas consumption and the market-leading smallest IRMS footprint make the Isologger MS right at home in the very harshest environments. This means you can interpret data from the machine in minutes, ensuring maximum on-station rig time. Time, after all, is of the essence.
What’s your gas?
When you’re determining the origins of gases, you need accuracy, wide dynamic range (200ppm to 50%) and precision. The Isologger MS them in abundance, providing data on whether a gas is bacterial or thermogenic, as well as its maturity. User communications is via WITS protocol
Wet or dry gas.
The data generated by the Isologger MS can easily determine if your gas is “wet” or “dry”. If Methane concentration of your sample exceeds 98% of the hydrocarbons, the gas is wet. If the gas contains Ethane, Propane, Butanes, Pentanes and Hexanes at combined concentrations of more than 2%, then the gas is dry.
C1 – C8
Unlike many competitor machines, the Isologger MS can provide information from C1 right up to C8. For cost-effectiveness, we’re often asked to focus our machines on C1 – C3, Methane, Ethane and Propane analysis but, because Isologger MS is so sensitive, you can rest assured that additional C3 – C8 information can be gained from extremely low concentration gas samples (200ppm). This additional information can help to determine the type of petroleum in your reservoir. Oil may be indicated by a higher abundance of C3+ components (Pentanes and Hexanes), whereas a “wet” gas can be dominated by Ethane.
Get your pay.
When it’s carrying out MGIL analysis, the Isologger MS can verify, show and identify potential bypassed or missed pays. This makes our machine a highly cost-effective tool, quickly paying back any initial capital outlay.
Isologger evidence of correction: Isolab
The Isolab system is a compact laboratory-based bench top system for Compound Specific Isotopic Analysis of Organic Gases. It uses the analysis technique of Gas Chromatography (GC) Combustion (C) Isotope Ratio Mass Spectrometer (IRMS) to measure the stable isotopes of 13C/12C in individual organic components in a mixture of organic gases.
The system is a small, low cost, easy to use, system for routine sample analysis.
The IRMS is the same as that used in the Isologger and hence has the same rugged characteristics with a small foot print.
A choice of Gas Chromatograph is available depending on the analytical requirements
The software plays an important role in the system performance in that the measurement and interpretation of the results is complicated by the large number of sample peaks that are produced during sample combustion. Data from each peak is collected and stored in a data base for post analysis manipulation. A calibration routine can be included in a batch analysis table so that routine multiple sample analysis can be perform against a standard sample.
The ID Microcarb system is a compact laboratory-based bench top system for the measurement of the of isotopes of carbon and oxygen in carbonates.
The sample can be in the form of a solid or Dissolved Inorganic Carbon in a liquid.
The system employs a classic Phosphoric acid digestion technique which produces carbon dioxide under control temperature conditions.
The system comprises an autosampler and rack containing temperature-controlled test tubes, an easily maintained automatic acid dispensing system and IRMS preparation unit.
The ID Microcarb is very compact and automated so that laboratory space efficiency is maximised.
