... stress. This paper presents a modified Lade criterion which has the following desirable qualities: it correctly describes the influence of the intermediate stress on rock strength, and therefore on wellbore stability, it can be rearranged to give a closed-form solution for critical mud weight...

... uniaxial stress problem; and an elastic anti-plane shear problem. The potential impacts of non-isothermal drilling processes on inclined borehole stability are illustrated through an application example. P. 443 wellbore design borehole stability stress cloud stability mud weight...

... materials can be removed efficiently. The mud weight required to maintain stability is substantially less for this type of borehole configuration that leads to reduced formation damages, and allows for the generation of a single hydraulic fracture parallel to the borehole rather than multiple fractures...

... difference between mud weight and reservoir pressure). This paper presents three different examples of stuck pipes directly related to rock mechanics problems. The first one results from a typical pack off in a highly unstable under compacted shale formation drilled in under balanced conditions. The second...

... of the Eastern Cordillera of the Andes, Colombia, South America. This has contributed to improved understanding of the causal effects of poor hole condition and drilling difficulties, and provided the basis for the development of a mud weight planning tool. Improved drilling performance has lead to savings...

... observed so far (breakouts, washout zones, undergauge sections) as well as their causes (lithology, tectonics, in situ-stresses, mud properties) are discussed. The operational impact of the instabilities (changes in mud system, increase in mud weight, vertical drilling strategy, sidetracks...
