Article
Full-text available
Many natural phenomena in geophysics and hydrogeology involve the flow of non-Newtonian fluids through natural rough-walled fractures. Therefore, there is considerable interest in predicting the pressure drop generated by complex flow in these media under a given set of boundary conditions. However, this task is markedly more challenging than the N...
Article
The flow of shear-thinning fluids through unconsolidated porous media is present in a number of important industrial applications such as soil depollution, Enhanced Oil Recovery or filtration of polymeric liquids. Therefore, predicting the pressure drop-flow rate relationship in model porous media has been the scope of major research efforts during...

Full-text available
Understanding non-Darcian flow of shear-thinning fluids through rough-walled rock fractures is of vital importance in a number of industrial applications such as hydrogeology or petroleum engineering. Different laws are available to express the deviations from linear Darcy law due to inertial pressure losses. In particular, Darcy's law is often ext...

Prior to the CO2 injection in the Rousse pilot operated by TOTAL Exploration Production France, baseline monitoring has been performed in near surface environments in order to characterize soil gas concentrations and soil gas fluxes behavior along with time. The baseline measurements were conducted in 2008 and 2009 on a quarterly basis. All investi...

We present an experimental investigation and modeling analysis of tracer transport in two transparent fracture replicas. The original fractures used in this work are a Vosges sandstone sample with nominal dimensions approximately 26 cm long and 15 cm wide, and a granite sample with nominal dimensions approximately 33 cm long and 15.5 cm wide. The a...

While it is generally assumed that in the viscous flow regime, the two-phase flow relative permeabilities in fractured and porous media depend uniquely on the phase saturations, several studies have shown that for non-Darcian flows (i.e., where the inertial forces are not negligible compared with the viscous forces), the relative permeabilities not...

Transport Properties of Lavoux Limestone at Various Stages of CO2-Like Acid-Rock Alteration - Since 2005, the French National Research Agency supports several scientific projects intended to select, validate and implement a geological site for CO2 storage in France. The work presented in this paper was carried out within the Geocarbone-Injectivity...
Article
Full-text available
Several on-site studies have been conducted on rock formations and soils where gases were collected into boreholes. The equipment consisted of packers isolating a chamber for gas collection. A pump allows gas transfer towards FT-IR sensors located at the surface. Such analytical approach shows several advantages for gas monitoring in boreholes: it...
Article
Full-text available
The porosity and the in situ concentration of tracer testing through different heterogeneous carbonate cores were performed using X-ray computed tomography. The results were interpreted using three approaches: the convection–diffusion equation, the arrival time moments and the stratified model. The results showed that (i) the Fickian approach led t...
Article
Full-text available
This article presents experimental results for single- and two-phase flows at high flow rates through a replica of an actual rough-walled rock fracture. The results of the single-phase flow are interpreted using non-Darcian laws: the weak inertia cubic law, Forchheimer's law, and the full cubic law. They allow the determination of the fracture's in...

Since 2005, the French National Research Agency supports several scientific projects intended to select, validate and implement a geological site for CO storage in France. The work presented in this paper is carried within the frame of the Geocarbone-Injectivity project 2 aimed to study the suitability of a carbonate deep saline aquifer located in...
Article
A phenomenological model based on the generalization of the single‐phase Forchheimer equation was recently proposed for predicting pressure drop and phase saturations in gas–liquid co‐current horizontal and downward high‐pressure packed beds. Here, we extend the model to packed‐bubble (co‐current upflow) and trickle‐bed operation using phase satura...
Article
The purpose of this paper is to examine the 3D effect on flows at high velocities through homogeneous porous media. Results of numerical simulations of a steady incompressible Newtonian fluid flowing through a 2D and a 3D periodic porous media performed at various Reynolds numbers are presented. The flow patterns are described and the pressure and...

This study concerns air and water two-phase flow at high velocities in porous media that is involved, among others, in petroleum and chemical engineering. It is generally assumed that when inertial forces are not negligible against viscous forces, the empirical Forchheimer equation is suitable to describe single-phase flow in porous media. We prese...

Recent work has been done in order to better understand the transport of hydrocarbons in the saturated zone. Phenomenological correlarions were proposed for the mass transfer coefficient. Unfortunately there is little agreement between those correlations as the mass transfer coefficient varies over several orders of magnitude. In this paper, a new...
Conference Paper
Predicting the rate of mass transfer in liquid-liquid systems is of crucial importance for the study of ground water contamination by hydrocarbons. Proposed correlations assume that mass transfer is strongly related to the interfacial area between the two immiscible fluids. In this paper, we present results of column experiments on the dissolution...

Dispersion and the mass transfer coefficients involved in the transport equation of a pollutant partially miscible with water saturating a porous media are estimated by a direct approach requiring the numerical solution of several local problems on representative unit cells of the porous media. An experimental set-up was used to study by gamma-ray...
