ABSTRACT:
Methods and apparatus for improving the quantitative measurement and detection of gas entrapped in drilling fluid during a drilling operation are disclosed. A sealed gas sampler is provided for agitating the mud to evolve gas samples. A known quantity of a standard gas is injected into the evolved gas stream. By monitoring the quantitative amount of the standard gas measured, the samples of evolved gas may be corrected for various error sources such as gas saturation of the sample stream.
