Compositional Gas Analysis

Compositional Gas Analysis

Bureau Veritas is the largest supplier of laboratory services to Canada's oil & gas industry

Whether it's natural gas, LPG, NGL, condensate or crude oil testing, our in-house laboratory staff can pool their expertise to offer valuable solutions to our customers.

  • Natural Gas, NGL & LPG Techniques

    Our proprietary technique for compositional analysis increases the ability to resolve, detect and quantify recovery of heavier end components and improves the overall accuracy of results

    Bureau Veritas uniquely leverages technology in the analysis of natural gas and natural gas liquids. Processors and mid-streamers are now able to generate more accurate and defensible valuations of their product streams when they depend on Bureau Veritas' enhanced natural gas liquid and extended natural gas analyses. It is now common for NGL streams to contain concentrations of C6 and C7+ components that are in excess of the analytical limits for industry standard procedures. We have combined procedural enhancements with the application of advanced chromatography to provide accurate and reliable production valuations.

  • Trace Sulfur Analysis

    Analysis of sulfur content in crude oil, refinery process units and in final petroleum products is needed in order to avoid refining and regulatory problems

    For more than 30 years, Bureau Veritas has been performing sulfur analysis on a variety of petroleum products such as natural gas, pressurized and atmospheric condensate, and other petroleum liquids. Analyses can range from total and elemental sulfur to trace sulfur compounds in the ppm and ppb range. The methods employed include gas chromatography/sulfur chemiluminescence (GC/SCD), UV fluorescence, X-Ray fluorescence (EDXRF), and the Clark-Lesage method.

    In addition to laboratory analysis, Bureau Veritas also has the ability to configure our mobile/portable lab to perform on-site trace sulfur analysis. This allows us to provide the client with near real-time data, so operational decisions can be made quickly.

  • Hydrocarbon Fingerprinting

    Is your reputation at stake?

    Could your operation be the actual source of the leak? Where and how do we sample? What do my results mean? If you need an answer to any of those questions - Bureau Veritas can help! We offer hydrocarbon fingerprinting for oil & gas clients with capabilities that are unparalleled.  Our turnkey solution - including highly experienced field sampling services and stable isotope analysis, in-house GC-IRMS analysis, expert data reporting and interpretation and a proprietary database of natural gas isotopic delivers results you can trust!

  • Benzene Emission & DEOS Reporting Services

    Are you compliant with the new benzene emissions requirements pertaining to directive 039?

    In 2013, Directive 039 “established mandatory requirements to ensure continued reductions of benzene emissions to reduce the potential impact on the public. Subsequently, the directive was updated in June of 2018.

    At Bureau Veritas, we can assist you with these questions and provide you with the right sampling and analysis required to ensure compliance with Directive 039. DEOS sheets are required and available for both operating and non-operating dehydrators. We can assist you in complying with the Directive 039, as we offer DEOS and Inventory List creation as part of our full-service commitment to our clients to meet the requirements of the directive.

    For more details on our benzene emissions services and capabilities, please see Benzene Emissions (attached)Added information on Directive 039 can be found through the Alberta Energy Regulator.
