A method of estimating one or more properties of an earth formation includes disposing a carrier in a borehole in an earth formation as part of an energy industry operation, receiving borehole fluid from the borehole, estimating at least one property of the borehole fluid associated with one or more intervals along the borehole, and generating a mud log that indicates values of the at least one property at the one or more intervals, the at least one property including at least one of gas content and cuttings content. The method also includes estimating, by a processor, one or more properties of the formation based on the mud log, the one or more properties selected from at least one of lithology, permeability, total organic carbon and brittleness, and controlling one or more operational parameters of the energy industry operation based on the one or more properties of the formation.

Estimation of formation properties based on borehole fluid and drilling logs

A method for correcting a fracture model of a reservoir includes receiving a seismic signal from seismic events due to a plurality of stimulated reservoir stages to provide detected seismic event information and estimating a number of undetected seismic events and a magnitude for each of the undetected seismic events to provide undetected seismic event information for each stage. The detected seismic event information and the undetected seismic event information provide corrected seismic event information for each stage. The method further includes calculating a scaling factor for each stage using a scalar property of the corresponding stage and a reference stage scalar property, applying the scaling factor for each stage to the corrected seismic event information to provide scaled seismic event information for each stage, and correcting the fracture model with the scaled seismic event information for each stage to provide a corrected fracture model.

An embodiment of a method for constructing a fracture network includes: receiving seismic data collected from a stimulation operation in an earth formation, the seismic data including seismic event data including a first seismic event associated with a first time increment and a second seismic event associated with a subsequent second time increment; and constructing a fracture network model. The model is constructed by: constructing an initial portion of the model based on the first seismic event; and subsequently updating the initial portion of the model based on the second seismic event.
