Optimization of core retrieval using a Thermo-Poro-Elastic (T-P-E) approach

In addition, during the modeling process, the contributing parameters have been identified. Having found the contributing parameters, using rig site data including the cuttings analysis (which is used to estimate several input parameters), it is not possible to find the value of the hydraulic diffusivity with certainty. So far, the magnitude of the tripping rate (finding the optimal value of which is the objective of the work) has been controlled just arbitrarily by the drilling crew. Therefore, these two parameters have been introduced as the main uncertain parameters and thus the sensitivity analyses of their effects have been investigated. Using this analysis, some extremes for tripping rates have been introduced, which can be used as a general engineered guideline for coring tool/method candidate selection.
