A network model that investigates electrical resistivity and capillary pressure curves of oil/water/rock systems for a full̄ooded cycle (primary drainage, imbibition and secondary drainage) is presented. This model uses a realistic pore geometry in the form of a grain boundary pore (GBP) shape and pore constrictions. The model also incorporates pore-scale displacement mechanisms and pore-scale w...

The Skempton pore pressure coefficient, B, is defined as the variation in with unit change confining under undrained conditions. B parameter an essential to consider coupled effects of solid–fluid compressibility and skeleton a porous system. It key factor exploring possible definition effective stress frozen soil. However, limited experimental theoretical research available literature give ins...

Generally seepage analysis and stress–strain analysis are conducted separately in the analysis of dams with varied water levels, which neglects the impact of soil deformation on seepage. The impact, however, is significant when the water level varies greatly. In this study, a simplified approach for consolidation analysis of unsaturated soil is used to conduct numerical simulations of water-fil...

Pore network models are used to relate fundamental pore structure parameters (pore body and pore throat size distributions) to the distribution of water at the pore level and the decay of proton magnetization under conditions of primary drainage in water-wet rocks. The simulations reveal conditions under which diffusive coupling between pores has a significant effect on the decay spectra and pr...

Hydroseismicity was proposed to explain the occurrence of intraplate earthquakes in regions. Koyna Warna region one of the reservoir triggered seismicity zone in India, which is an example of intraplate earthquake region. The seismicity is continuing after 45 years of impoundment of the Koyna reservoir in 1961 and 25 years of impoundment of Warna reservoir in 1985. The excess of previous maximu...

The swath bathymetric data acquired during the “Sumatra Aftershocks” cruise from the Sunda trench in the Indian Ocean to the north of the Sumatra Island imaged several scars and deposits. In situ pore pressure measurements using the Ifremer piezometer and coring demonstrate that high excess pore pressure and sediment deformation was generated by a recent event in the scar of the slope failure z...

Numerous methods have been developed for measuring mechanical properties of bilayer lipid membranes (BLMs) such as the Young’s modulus, strength, bending modulus, and others. This paper introduces a new method for measuring the maximum pressure that can be withstood by BLMs formed over a porous substrate. This quantity, referred to as the failure pressure, has not been reported in the literatur...
