[2]LTHE, Grenoble, France

The efficiency of bioreactor lanfills depends on a homogeneous distribution of leachate in the waste body. Therefore, optimisation of leachate injection systems is a challenging issue for operators. Most studies have shown that surface Electrical Resistivity Tomography (ERT) can be a ... Read More

Impact Assessment of Hydrologic and Operational Factors on the Efficiency of Managed Aquifer Recharge Scheme

M.A. Rahman[1], P. Oberdorfer[1], Y. Jin[1], M. Pervin[1], E. Holzbecher[1]
[1]Department of Applied Geology, Geoscience Center, University of Göttingen, Göttingen, Lower Saxony, Germany

Due to increased demands on groundwater accompanied by increased drawdowns (ca. 2-3 meters/year), technologies that use alternative water resources have been suggested for Dhaka City, Bangladesh. Preliminary studies show that managed aquifer recharge (MAR) would help in optimal use of ... Read More

为研究不同加热方式下煤岩内部裂隙在热力耦合作用下的变形特征,建立了微波和常规加热两种数值模型,考查了不同温度场分布特征下裂隙周边应力应变场的变化过程。研究结果表明:微波加热,温度场分布具有内高外低的特征,此时裂隙周边分布的应力多为压应力,且数值较大,裂隙边界位移表现为向内收缩;常规加热,温度场分布具有外高内低的特性,此时裂隙周边分布应力多为拉应力,但量值较低,裂隙边界位移表现为向外扩张;热源越靠近裂隙压应力越明显,反之拉应力明显。 Read More

3D Modeling of Fracture Flow in Core Samples Using ?-CT Data

Knowledge on flow behavior in fractured reservoir rocks is of great interest in petroleum engineering as well as for geothermal assets. Due to the big difference of magnitude (fracture aperture: ~?m, lateral extension of reservoirs ~km), modeling of discrete fracture flow is not ... Read More

Numerically Generated g-functions for Ground Coupled Heat Pump Applications

J. Acuna[1], M. Fossa[2], P. Monzó[1]
[1]KTH Energy Technology, Stockholm, Sweden
[2]Dime, University of Genova, Genova, Italy

Ground-coupled heat pumps (GCHP) are successfully installed since at about 20 years in many countries to fulfill space conditioning requirements in building applications. In most cases the heat pump is connected to a system of vertical ground heat exchangers (as illustrated in Figure 1) ... Read More

Numerical Simulation of Quasi-steady-state Gas Flow in a Landfill

Q. Zheng [1],
[1] Zhejiang University, Hangzhou, Zhejiang, China

Landfill is currently the most dominating method to dispose wastes, which are caused by the lives of residents and constructions of cities and towns. Because of large amounts of organic substances in landfills, they will undergo continuous microbial degradation, which generates a lot of ... Read More

Modeling of the Heat Transfer Between a CO2 Sequestration Well and the Surrounding Geological Formation

[1]Mechanical Engineering, Dalhousie University, Halifax, NS, Canada
[2]Process Engineering and Applied Science, Dalhousie University, Halifax, NS, Canada

In a carbon sequestration system CO2 would be pumped down a well and into a reservoir at supercritical temperatures and pressures. An important consideration is the long term stability of the reservoir. The goal of these simulations is to thermally model the injection well and ... Read More

Elastoplastic Deformation in a Wedge-Shaped Plate Caused by a Subducting Seamount

M. Ding[1], J. Lin[2]
[1]MIT/WHOI Joint Program in Oceanography, Cambridge, MA, USA
[2]Woods Hole Oceanographic Institution, Woods Hole, MA, USA

We used COMSOL Multiphysics 4.3 to simulate the 2D elastoplastic deformation and plastic strain in a wedge-shaped plate above a subducting interface. The modeling results reveal that a pair of conjugate normal faults would first appear in the thinner part of the plate. Subsequently, a ... Read More

Numerical Simulation: Field Scale Fluid Injection to a Porous Layer in Relevance to CO₂ Geological Storage

S. Kim[1], S. A. Hosseini[1], S. D. Hovorka[1]
[1]Bureau of Economic Geology, The University of Texas at Austin, Austin, TX, USA

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... Read More

Ability of Single-Well Injection-Withdrawal Experiments to Estimate Ground Water Velocity

F. Maier[1], K. Hebig[2], Y. Jin[1], and E. Holzbecher[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany
[2]Technical University Berlin, Berlin, Germany

The authors present a closer look on the Single-Well Injection-Withdrawal Experiment (SWIW) or Push-Pull Experiments and its ability to determine the groundwater velocity, as one of the major parameters concerning reservoir management and underground reservoir characterization. The flow ... Read More
