Permeability of Fractured Media under Confining Pressure: A Simplified Model
An elastic-plastic model was developed to describe the deformation and permeability of fractured rocks under confining pressure. Elastic and elastic-plastic contact models were used in the model to analyze the deformations of a representative element containing a single fracture under various confining pressures. The present work utilized elements from contact mechanics and viscous flows to der...
متن کاملLaboratory observations of permeability enhancement by fluid pressure oscillation of in situ fractured rock
[1] We report on laboratory experiments designed to investigate the influence of pore pressure oscillations on the effective permeability of fractured rock. Berea sandstone samples were fractured in situ under triaxial stresses of tens of megapascals, and deionized water was forced through the incipient fracture under conditions of steady and oscillating pore pressure. We find that short‐term p...
متن کاملThe Permeability of Ablative Materials Under Rarefied Gas Conditions
Numerical meshes of both cork and carbon fibre ablative materials in their virgin and pyrolised states, with realistic porosity and tortuosity, have been created from micro-computed tomography (μCT) scans. The porosity of each material has been calculated from the μCT scans and used to extract smaller representative sample volumes to perform numerical simulations on. Direct simulation Monte Car...
متن کاملAnalysis of High Pressure Samples by Gas Chromatography
High molecular weight compounds dissolved in gases at elevated pressures and temperatures in reservoirs often present production problems. These can range ftom precipitation of solids which foul chillers and tubing to plasticizing membranes used for gas component separations. Quantitative analysis of such samples is problematic because they are frequently present in sample vessels as two phases...
متن کاملPermeability of electrospun fiber mats under pressure driven flow
Hydraulic permeability of electrospun fiber mats under flow-induced compression has been modeled and verified experimentally. The permeation model accurately estimates the changes in solidity, and hence the permeability of the electrospun mats, over a range of pressure differentials. The model is based on Darcy’s law applied to a compressible, porous medium, using Happel’s equation for the perm...
