Numerical Implementation of a Critical State Model for Soft Rocks [PDF]
, 2018 This paper details the basic tasks for the numerical implementation of a simple elasto-plastic critical state model for bonded materials (i.e. soft rocks-hard soils) into the finite element program SNAC developed at the University of Newcastle in ...

Особливості визначення коефіцієнта газонасичення пластів-колекторів із глинисто-карбонатним типом цементу [PDF]
, 2013 Гірські породи, які виповнюють продуктивні розрізи багатьох нафтогазових родовищ, характеризуються глинисто-карбонатним типом цементу. Для такого роду порід-колекторів заміщення глинистого цементу на карбонатний призводить до збільшення їх питомого ...

Provenance history of a Late Triassic-Jurassic Gondwana margin forearc basin, Murihiku Terrane, North Island, New Zealand: petrographic and geochemical constraints [PDF]
, 2004 The Murihiku Terrane in the North Island was a forearc basin adjacent to a volcanic arc along the eastern margin of Gondwana during the Mesozoic. The rocks that infill the basin are mainly volcaniclastic sandstones and mudstones, often turbiditic, with ...

Study on time-dependent injectability evaluation of mudstone considering the self-healing effect
Open GeosciencesThe injectability of mudstone is a key parameter for grout modification and is affected by hydration. Inherent injectability is predominantly determined by pore size distribution nuances, encompassing both the critical pore size and the heterogeneity ...

Remote infrared spectroscopy of the earth [PDF]
The infrared reflexion-spectra of minerals and rocks are used for remote sensing of targets. The reflexion-spectra of silicate rocks vary quite significantly from mineral to mineral in the wave length region from 8 to 12 micrometers.

Compressional wave dispersion due to rock matrix stiffening by clay squirt flow
Geophysical Research Letters, 2016 The standard Biot‐Gassmann theory of poroelasticity fails to explain strong compressional wave velocity dispersion experimentally observed in 12 tight siltstone with clay‐filled pores.

Faulting of a turbidite sandstone-siltstone successions: the case study of the Macigno Formation, Tuscany, Italy [PDF]
, 2016 Faults in siliciclastic rocks are characterized by a great variability of fault zone architecture and relative permeability properties. This is because siliciclastic rocks (i.e turbidites) are often represented by alternating beds of various thickness ...

Retention processes in clay-rocks
, 2015 Within the context of the clay barrier concept for underground nuclear waste storage, montmorillonite and bentonite have been widely used as reference materials for radionuclides (RN) retention studies. Associated modeling work aims at understanding and predicting the retention of RN in clay-rocks where clay minerals are assumed to be representative of
