Abstract: A method for measuring gas volume during mudlogging of a subterranean field operation may include obtaining measurements for a plurality of parameters associated with a core sample retrieved from a subterranean formation, where the plurality of parameters are measured while the core sample is under downhole conditions, and where the plurality of parameters comprises a volume of fluid in a gaseous state. The method may also include applying the measurements to an algorithm to generate a calibrated algorithm, where the calibrated algorithm is used to generate an output based on measurements made during the mudlogging.
