METHODS AND SYSTEMS FOR PREDICTING FLUID TYPE WHILE GEOSTEERING

Abstract: a method for predicting fluid properties includes measuring one or more measured fluid properties of a mud gas at a surface of a wellbore. the method also includes measuring one or more mud gas properties of the mud gas at the surface of the wellbore. the method also includes predicting one or more first predicted fluid properties using one or more pre-trained machine-learning (ml) models. the one or more first predicted fluid properties are predicted based at least partially upon the one or more mud gas properties. the method also includes comparing the one or more measured fluid properties to the one or more first predicted fluid properties. the method also includes re-training the one or more pre-trained ml models to produce one or more re-trained ml models in response to the comparison.
