One gram of soil can contain up to 100 million to 1 billion microrganisms and up to 1 million different species of microorganisms. Despite this fact, geotechnical engineers have, until fairly recently, ignored biological activity in the soil or possible biological amendments that could be introduced. Over the last ten years research has focused on bioaugmentation strategies (i.e. the injection...

Among the known EOR techniques which have been investigated and tested during last decades the solvent injection proved to reach one of the best recovery factors. From the other side the solvent retention problem makes it relatively expensive and thus less attractive.

Although pore-scale models are used to compute macroscopic average properties required in field-scale simulators, most work is limited to small sample size. There is a need for pore-scale...

Surfactants can drastically reduce the water/oil interfacial tension (IFT) to mobilize residual oil. However, surfactant flooding is viscously unstable inherently because of its large mobility ratio. Alkaline/surfactant/polymer (ASP) flooding has been serving as a conventional solution, where polymer plays a vital role in increasing viscosity for a more stable oil bank. Recently, a...

As length scales grow smaller, the behavior of two fluids flowing through a porous media is more and more strongly affected by capillary pressure. The canonical Young-Laplace equation gives a good estimate of the pressure change across fluid interfaces, but it is technically valid only in equilibrium conditions. It is well-known that for two fluids flowing in capillaries, the interfacial...

Polymer flooding is one of the most commonly applied enhanced oil recovery technique. The main mechanism of polymer flooding is the increased sweep efficiency by increase injected water viscosity, which would reduce fingering, improve water injection profile and reduce the relative permeability of water flow.

A high order method is formulated for solving the miscible displacement problem and modeling viscous fingering. Viscous fingering in porous media may occur when a fluid with low viscosity is used to displace a fluid with high viscosity. For this type of flow instability, a tiny perturbation can be amplified exponentially, which triggers a finger-like pattern in the fluid concentration profile...

Gas hydrates are crystalline solids formed when water molecules form a cage-like structure and trap a large number of gas molecules within. Gas hydrates are thermodynamically stable under conditions of low temperature and high pressure and occur in nature typically in permafrost regions and marine off-shores. If warmed or depressurized, hydrates destabilize and dissociate into water and...

The physical processes governing flow and transport in porous media span a wide array of spatial scales. Furthermore, in many applications it would be computationally intractable to resolve each scale of interest. To still capture the effects of the smaller-scale processes, one option is to couple together models of different dimensionality. In e.g. vascularized tissue and root networks, the...

The use of energized fluids in hydraulic fracturing helps minimize formation damage and enhance well productivity especially in water sensitive reservoirs. Many current fracking simulators use single phase and incompressible flow assumptions to model the fracturing fluids. The thermal and compositional effects of using energized fluids on fracture topology are neglected by such simulators.

Treatment of water for human consumption often involves filtration through reactive porous media, such as activated carbon, or metal oxides. The sorption of contaminants inevitably leads to a depletion of available free sites and therefore a decrease in efficiency. A possible technique to regenerate filtration systems is the use of chelation agents. Such compounds, i.e. ...

Dr Mingqiang Wei (Southwest Petroleum University)17/05/2018, 15:14MS 1.20: Porous media evolving mechanism, theory and its applications in energy engineeringOral 20 Minutes
In petroleum engineering, the production decline type curves for the analysis and interpretation of production data has been considered as a robust method to obtain the flow parameters, and original gas in place etc. However, most of the previous production decline analysis model focused on primary depletion with closed boundary, rather than secondary depletion with water influx/waterflood....

In continuum modeling of porous media, it is necessary to characterize microscopic features of the pore space using a small set of continuum-scale parameters, such as porosity, tortuosity, etc., which are then linked to transport coefficients or other macroscopic properties. For phenomena that depend on the physical dimensions of pores, the pore-size distribution is also commonly used. It is...

Bernd Crouse (Exa Corporation)17/05/2018, 15:32MS 1.23: Challenges in porous media characterization and modelling of multiphase flow with capillarityOral 20 Minutes
We present a detailed analysis of a “full physics” simulated drainage-imbibition capillary pressure hysteresis on a packed sphere test case, with particular focus on the fluid displacement mechanisms. The chosen LBM-based flow simulator includes a surface-element boundary scheme to ensure accurate surface treatment and robust handling of arbitrary geometries even in low grid resolution...

Mr Jagannath Upadhyay (Louisiana State University)17/05/2018, 15:32MS 3.05: Advanced methods for micromodel fabrication and diagnostics withinOral 20 Minutes
Micro-models are microfluidic devices used to study the transport of fluids in porous media domains. Porous media relevant to subsurface engineering and reservoir applications are 3D in nature. In order to observe and measure the transport and behavior of nano-particles through such media, it is necessary to preserve the 3D characteristics of the relevant geometry and flow while facilitating...

Dr Xavier Raynaud (SINTEF)17/05/2018, 15:32MS 2.03: Challenges in flow and transport simulations in poro-fractured media: numerical methods and modelingOral 20 Minutes
Accumulation of large particles on well faces decreases the injectivity. This issue is particularly accute in the case of produced water reinjection (PWRI) and polymer flooding. To maintain operational rates, the injection pressure is increased, which causes fracturing or reopening of existing fractures. Then, the injectivity may be recovered or even increased, but only temporarily, as filter...

Bin Wang (Louisiana State University)MS 4.13: Natural and engineered nanoparticles in porous media: experimental findings and modeling approachesPoster
Modeling nanoparticle (NP) transport in porous media is an important research topic in many subsurface engineering applications, such as enhanced oil recovery (EOR), fracture electromagnetic imaging and environmental remediation. An efficient field-scale simulation framework is critical for predicting NP performance and designing subsurface applications. In this work, an efficient...

Prof. Moran Wang (Tsinghua University Department of Engineering Mechanics )GS 3: Experimental achievementsNo preference
Surface charge at solid-electrolyte interface is generally affected by the local physical and chemical properties in the solution such as ionic strength, pH and so on. In a system with concentration or pH variation, rather than the prevailing assumption of homogeneous surface change, it leads to a spontaneous inhomogeneous distribution of surface charge, which has been observed in geotechnical...
