TL;DR: This chapter attempts were made to introduce the SVM, its principles, structures, and parameters, and it seems that the cross-validation approach would be the best technique for parameter selections of SVMs.

TL;DR: In this article, the authors provide a deeper insight into drilling through shale formations by providing few approaches for different circumstances, and it appears that silicate based muds and thermally activated mud emulsion (TAME) are the best option to mitigate shale related issues, but more studies are required to provide a permanent solution for this very complicated issue.

TL;DR: In this article, the authors evaluated the variation of brittleness in one of the gas shale reservoirs located in the north Perth Basin of Australia, and indicated that the lower part of the Carynginia shale should be selected for a hydraulic fracturing job due to a high BRI index, although a careful analysis of Total Organic Content (TOC) might be required before initiating any plans.

TL;DR: In this article, an analytical approach based on the theory of thermo-poroelasticity was presented to predict the possibility of cement sheath failure in deep structures, which indicated that a thicker cement can withstand a higher load applied by the formations and protect the casing against a significant collapse pressure.

TL;DR: In this paper, the effect of uncertainty on the estimation of safe mud weight window (MWW) using different failure criteria was analyzed using quantitative risk assessment, and the results indicated that Mogi-Coulomb and Hoek-Brown are more robust against the uncertainty of input parameters and mud weight used for this wellbore could have slightly been increased to reduce the shear failure of the borehole wall.
