  • Gas extraction calibration system and methods
    Patent number: 10180062
    Abstract: A system and method calibrate efficiency of a gas extraction system in extracting hydrocarbons from mud flowing in a drilling operation. A background reading of a hydrocarbon is extracted from the mud flowing in the drilling operation with the gas extraction system and is checked for stability. An injection operation injects a known concentration of the hydrocarbon into mud, and a subject reading of the hydrocarbon is obtained with the gas extraction system during the injection operation. A correction factor of the hydrocarbon is determined for the gas extraction system by comparing the subject reading against its corresponding known concentration. Then, at least one operational reading of the hydrocarbon extracted from the mud with the gas extraction system can be corrected using the determined correction factor.
