TL;DR: In this article, the authors proposed an evaluation method of brittleness index based on energy method, established the evaluation model based on three types of damage constitutive relations, and finally analyzed the effects of the damage variable of peak strain of different types of different rocks on brittiness.

TL;DR: In this paper, the authors developed an integrated evaluation model through the analyses of a significant amount of actual historical data, which includes six subcomponent models, ranging from the subsurface reservoir to infield flowline.

TL;DR: In this paper, the pore structure characteristics of isolated organic matter and its corresponding bulk shales were investigated for five high matured marine shale samples from the Lower Silurian Longmaxi formation in south China using X-ray diffraction (XRD), total organic carbon content (TOC) tests, field emission scanning electron microscope (FE-SEM) observation and ultra-low pressure nitrogen gas physisorption.

TL;DR: In this paper, a multi-linear analytical solution is obtained from the diffusivity equation, which considers wellbore storage effects, stress-dependent and non-Darcy flows considering threshold pressure gradient.

TL;DR: In this article, a coupled flow-stress-damage (FSD) model of hydraulic fracture propagation with gravels is established, and the result provides the theoretical support for prediction of fracture propagation morphology and plan design of hydraulic fracturing in the glutenite reservoirs.
