Reservoir Characterization from Gas Ratio Analysis Using New High Efficiency Gas Extraction System

Mud logging gas detection and chromatography have been traditionally used as indicators of hydrocarbon<br>occurrence and wellsite safety. However, the application of mud logging gas as a reliable reservoir characterization tool had<br>previously been hindered by its semi-quantitative nature, noticeably the inability to get repeatable responses in all<br>environments so that the analysis can be used as a trusted analytical tool, regardless of gas trap operating conditions and<br>surface environments.
