The in-situ stress fields are of great importance in the interpretation of tectonic features and
the analysis of hydrocarbon systems. In this work, we determine the in-situ stress field, pore …

Mechanically-based numerical modeling is a powerful tool for investigating fundamental
processes associated with the formation and evolution of both large and small-scale …

The bottom-hole pressure of hydraulic fracturing in ductile reservoirs is much higher than
that of the hydraulic fracturing simulation, and the fracture toughness inferred from the field …

Problems concerning the influence of the geometric parameters of an undercutting anchor
on the range of the failure zone of rock medium during the pulling out of the anchor …

The increasing exploration and production in unconventional resource plays in the past
decade has been accompanied by a greater need for understanding the effectiveness of …

A micro-annulus (MA) is defined as a high permeability zone or gap initiating/occurring at
the casing-cement and cement-formation interfaces during the wellbore life span. An MA can …

Understanding the rock mass deformation and stress states, the fracture development and
distribution are critical to a range of endeavors including oil and gas exploration and …

The numerical simulation of penetration into rock is an important tool to gain insights into
rock drilling mechanisms, since it can be exploited as an alternative to the expensive field …

Estimating formation permeability is crucial for production estimation, hydraulic fracturing
design optimization and rate transient analysis. Laboratory experiments can be used to …

Tectonic fractures are otherwise known as joints or fissures. The density of tectonic fractures
is governed by the lithology, layer thickness and structures. The distribution and density of …
