Onsite DST Gas & Liquid Analysis: A DST is the ideal opportunity to obtain critical information on produced fluids for field development, process design and for pipeline specification. It is not always possible or applicable to obtain this information in a laboratory environment due to various factors such as trace concentrations, reaction/losses to sampling cylinders, short half-life and sample volume requirements. Onsite analysis during an extended flow period enables Core Lab to provide our clients with the most accurate and reliable data for several key components such as Hydrogen Sulphide (H2S), Total Mercaptans, Mercury and Radon.
