It has become an inevitable trend of human development to seek resources from the deep
underground. However, rock encountered in deep underground engineering is usually in an …

Abstract Support Vector Machine (SVM) has been introduced in the late 1990s and
successfully applied to many engineering related applications. In this chapter, attempts were …

CO 2 injection for storage in subsurface geologic medium is one of the techniques
developed in the past years to mitigate anthropological CO 2. Prior to CO 2 injection, it is …

The wellbore stability of a vertical well through the sandstone reservoir layers of the Asmari
oil-bearing formation in south-west Iran is investigated. The safe drilling-fluid density range …

This work presents the assessment of present-day stresses and pore pressures in a prolific
onshore hydrocarbon bearing field located in the southern Cambay Basin, western India …

Determination of in-situ stresses is essential for subsurface planning and modeling, such as
horizontal well planning and hydraulic fracture design. In-situ stresses consist of overburden …

In this study, a comprehensive integrated geomechanical analysis has been performed for
the construction of a one-dimensional Mechanical Earth Model (MEM) for a vertical well …

Abstract Analysis of wellbore instability contains evaluation of rock mechanical properties
and the state of in-situ stresses. In this analysis the only convenient factor is the mud weight …

A Permian igneous formation in the Sichuan Basin typically exhibits complex lithology,
strong heterogeneity, and strong uncertainty; consequently, there is a very high risk of …

This work interprets the pore pressure distribution and in-situ stress magnitudes in the~
10,600 feet thick Neogene succession of the West and South Al-Khilala gas fields, onshore …
