摘要

Summary “Well site gas extraction and analysis system, method for determining a well site gas extraction efficiency coefficient and well drilling method” methods and systems for monitoring, analyzing and characterizing well holes and reservoir fluids in an underground formation are provided. In particular, methods and systems for determining and using correction coefficients for the quantitative analysis of gas samples extracted from fluids at a well site based on fick diffusion laws are provided. In one embodiment, the systems comprise: a gas trap configured to extract one or more gas samples from a fluid at a well site; a gas analyzer configured to receive one or more gas samples from the gas extraction system and generate data relating to the amount of one or more gas species present in the gas sample; and a gas analyzer communicably coupled information processing system that is configured to use data received from the gas analyzer to determine an extraction efficiency coefficient for the gas species. 1/1
