Borehole stability issues are always a spotlight in drilling activities because of their costly
consequences, including borehole collapse, lost circulation, stuck pipe etc. Wellbore …

This paper presents the development of a model for determining wellbore stability for oil and
gas drilling operations. The effects of mechanical forces and poroelasticity on shale …

This paper presents closed-form solutions for the pore pressures and stress fields for the
inclined borehole and the cylinder, induced by boundary stress perturbation in an …

Chemical and mechanical coupling are the most important factors affecting wellbore
instability. The main objective of this research is to propose a wellbore stability analysis …

A porothermoelastic solution of the general problem of the inclined borehole in a
transversely isotropic porous material is presented herein and compared with the isotropic …

This paper reviews some of the progress made on wellbore stability modeling during the last
two decades. First we demonstrate the improvement made on mud-pressure predictions by …

Drilling efficiency can be improved by optimizing the drilling fluid parameters such as
density, salt concentration, and temperature. Selection of an appropriate mud can benefit …

This work presents an analytical solution for an inclined wellbore drilled in a fractured
formation displaying a high contrast between the diffusion rates in the fractures and in the …

Lost circulation, a major complication of drilling operations, is commonly treated by adding
materials of various types, shapes, and particle-size distributions to the drilling mud …

Optimization of drilling fluid parameters such as mud weight, salt concentration, and
temperature is essential to alleviating instability problems when drilling through shale …
