Fracture toughness property is often ignored but has a significant impact on the hydraulic
fracture design, ie length and height. It represents the resistance of the rock to hydraulic …

As typical low-permeability unconventional fossil resources, tight sandstone oil cannot be
exploited economically without effective hydraulic fracturing. Fracability is a term commonly …

Microtextures in lacustrine fine-grained sedimentary rocks generally include the basic
features of quantity, size, shape and arrangement of particles, which are the internal factors …

The effect of confinement pressure on fracture toughness may be significant in materials with
poor tensile strength, as is the case of most rocks. In fracking wells for hydrocarbon …

This master thesis details the determination of mode I (tensile) fracture toughness, KIC,
using the International Society of Rock Mechanics (ISRM) Chevron Bend (CB) method on …

Mode I fracture mechanics tests of mostly calcareous Vaca Muerta shale rocks were
performed in a new experimental device. A hydraulic system allows the injection of …

With the increasingly extended application of hydraulic stimulation for unconventional
reservoirs, and the production of hydrocarbons thereof, it became clear that weak interfaces …

Abstract The North American success of unconventional oil development from marine shales
has inspired the global liquid-rich shale (LRS) exploration and production trend. Resource …

Pakistan holds significant volumes of unconventional hydrocarbon reserves. In 2013 EIA
report, the Sembar Formation of the Lower Indus Basin has 101 Tcf shale gas with 5.8 billion …
