1. A method for predicting fluid properties, the method comprising:
measuring one or more measured fluid properties of a mud gas at a surface of a wellbore;
measuring one or more mud gas properties of the mud gas at the surface of the wellbore;
predicting one or more first predicted fluid properties using one or more pre-trained machine-learning (ML) models, wherein the one or more first predicted fluid properties are predicted based at least partially upon the one or more mud gas properties;
comparing the one or more measured fluid properties to the one or more first predicted fluid properties;
re-training the one or more pre-trained ML models to produce one or more re-trained ML models in response to the comparison;
predicting one or more second predicted fluid properties using the one or more re-trained ML models, the one or more second predicted fluid properties comprise a fluid type, a fluid composition, a gas-oil ratio (GOR), or a combination thereof;
comparing the one or more measured fluid properties to the one or more second predicted fluid properties; and
determining a geosteering response for a downhole tool that is drilling the wellbore in response to the comparison being less than a predetermined threshold.
