Flow of non-Newtonian fluids in rock fractures is ubiquitous in engineering practice and
involves eg cement flow in tunnel grouting, drilling fluid flow when a fracture is met during …

This study focuses on experimental evaluation of the Forchheimer equation coefficients for
non-Darcy flow in deformable rough-walled fractures. Water flow tests through twelve granite …

The objective of this paper is to investigate the effects of wall surface roughness on fluid flow
through rock fractures. A wavelet analysis technique was developed to define a …

This study experimentally investigated the nonlinear flow characteristics at low Reynolds
number through rough-walled fractures subjected to a wide range of confining pressures …

Transient pulse tests were performed on single rock fractures at different confining
pressures. A new data analysis method based on polynomial fitting was introduced to …

Successful acid fracturing operation could reduce formation damage and increase
production rate in a carbonate reservoir. Final fracture conductivity is a critical parameter that …

In this work, we present a perturbation solution for the flow of a pseudoplastic fluid injected
into a fracture. Such fluids are often used in enhanced oil recovery operations. The forcing …

The influence of roughness, aperture and asperity irregularity on fluid flow regimes in rough
rock fractures was investigated by performing coupled triaxial water flow tests and fluid …

Foam generation for gas mobility reduction in porous media is a well-known method and
frequently used in field applications. Application of foam in fractured reservoirs has hitherto …

Tight multilayered hydrocarbon reservoirs are typical in unconventional oil and gas
extraction, in which widespread bedded interfaces have crucial effects on hydraulic …
