Pore-scale characterization and modelling of CO2 flow in tight sandstones using X-ray micro-CT; Knorringfjellet formation of the Longyearbyen CO2 lab, Svalbard [PDF]

open access: yes, 2014
Rocks of the Knorringfjellet Formation in Central Spitsbergen form a potential storage reservoir for CO2 below Longyearbyen. They are characterised by a moderate porosity and low permeability.

Effect of the Initial Support of the Tunnel on the Characteristics of Rockburst: Case Study and Mechanism Analysis

open access: yesAdvances in Civil Engineering, 2022
Rockburst is still a stubborn disease in the field of engineering geology. The present research pays more attention to the influence of geological conditions on rockburst and less to the influence of type and stiffness of engineering support on rockburst.

Fracture system in shale gas reservoir: Prospect of characterization and modeling techniques

open access: yesJournal of Natural Gas Geoscience, 2021
The quality and production of shale gas are directly dependent on the development of fractures. Especially in large-scale fracturing development, natural and hydraulic fractures play significant roles.

A theory of fracture of materials and its application to geology

open access: yesEos, Transactions American Geophysical Union, 1950
A theory of fracture of materials is developed which encompasses shear and tension failure. The probability of fracture occurring across a given surface element in an isotropic medium is assumed to be a general function of the limiting normal and tangential stresses across that element. A modification is later introduced to allow for anisotropy wherein

Plate motions recorded in tectonostratigraphic terranes of the Franciscan Complex and evolution of the Mendocino triple junction, northwestern California [PDF]

open access: yes, 1994
The Mendocino triple junction area of northern California is underlain by the Coastal belt of the Franciscan complex, flanked on the east by the Central and Eastern belts of the Franciscan Complex.

Connectivity Evaluation of Fracture-Cavity Reservoirs in S91 Unit

open access: yesApplied Sciences
Carbonate fracture–cavity reservoirs are significant oil and gas reservoirs globally, and their efficient development is influenced by the connectivity between fracture–cavity units within the reservoir. These reservoirs primarily consist of large caves,
