  • Patent number: 9482089
    Abstract: An example system for receiving gas expelled from a core sample of a formation may include a tubular element. A core chamber may be disposed within the first tubular element. A gas and drilling fluid separator may be in fluid communication with the core chamber. The tubular element may be an inner barrel assembly of a core sample assembly that is disposed within a borehole. A core sample may be contained within the inner barrel assembly and may be retrieved at the surface. Gas may be expelled from the core sample as it is retrieved, and the gas and drilling fluid separator may separate the expelled gas from suspension with a drilling fluid for analysis.
