Mechanism of Borehole Stability in Fractured Formation With Discrete Fracture Network
Due to the high degree of rock block dispersion and the extensive development of natural fractures in the fractured formation, the drilling fluid loss and wellbore instability accidents occur frequently during the drilling process.

Analysis of Wellbore Stability considering the Interaction between Fluid and Shale
Reservoir shale has the characteristics of bedding planes, strong anisotropy, and strong imbibition ability under ultralow water saturation, which has an important impact on wellbore stability of horizontal wells.

Experimental Study of Wellbore Instability in Clays [PDF]
This paper presents the results of an extensive program of laboratory model wellbore tests that have been performed to study wellbore instability in saturated clays. The tests were conducted on resedimented Boston blue clay (RBBC) anisotropically consolidated to vertical effective stresses up to 10Â MPa by using two custom-built thick-walled cylinder ...

Prediction of the lifespan of cement at a specific depth based on the coupling of geomechanical and geochemical processes for CO2 storage [PDF]
The injection of carbon dioxide (CO2) captured from combustion-based processes into underground formations is one of a number of plausible methods to reduce its release into the atmosphere and consequential greenhouse gas warming.

Assessment of zonal isolation risk to changes in design parameters [PDF]
The Well Containment Screening Tool (WCST) focuses on well integrity evaluation after well control incident. The WCST favors a greater wall thickness and, hence, a narrower cementing annulus, potentially increasing the risk of cement loss.

Development of configurational forces during the injection of an elastic rod [PDF]
When an inextensible elastic rod is 'injected' through a sliding sleeve against a fixed constraint, configurational forces are developed, deeply influencing the mechanical response.
