Dissolved Methane Monitoring – The Marcellus Shale Coalition Study

Regulations Without a Robust Analytical Method

 

Regulators in several states, including Colorado, require oil and gas operators to analyze and document pre- and post-drilling water quality for dissolved methane and other light gases.    If action levels are exceeded, the operator is required to address exceedances.  At least one state automatically assigns liability to the operator when post-drill results exceed baseline values. 

 The objective of the Marcellus Shale Inter-laboratory Study was to determine how much variation existed across laboratories using the industry standard EPA procedure and to identify causes of the expected large variation. 

 Three phases of inter-laboratory studies were conducted showing unacceptable spread across the laboratory community.   To address this variability, additional phases focused on which laboratory protocols would provide the most defensible lab results and to assist participating laboratories in making revisions to their protocols for preparation, handling, calibration, and sample analysis techniques. 

John Watson will provide a short overview of the regulatory framework for baseline sampling of dissolved methane and light gases and proposed federal revisions followed by a more detailed discussion of the Marcellus Shale Coalition’s (MSC) three-phase inter-laboratory study addressing the lab protocols for sample analysis.   One of the principle authors of the MSC lab study – David Gratson of Environmental Standards, Inc. –  will be in attendance and available to answer questions.
