Abstract
A method for removing a core sample from a borehole includes: taking the core sample within the borehole with a sampling tool; generating a model of the core sample, the model based on data representing properties of the core sample; defining a plurality of proposed tripping schedules; applying, by a processor, the plurality of proposed tripping schedules to the model, and estimating a core parameter for each of the plurality of proposed tripping schedules; comparing the core parameter to a criteria; and selecting a suitable tripping schedule based on the comparison.
