This paper is a part of a study on energy piles for heating and cooling of buildings. Energy piles are used for two reasons: (1) to transfer structural loads to foundation soils, and (2) to transfer heat from foundation soils to the building for space heating in winter time and for cooling purposes in summer time by transferring heat from the building to the foundation soils. The efficiency of ...

Significant volumes of the worlds proved reserves are in dolostone reservoirs. Scope for recovery and success/upside of new exploration plays depend on the chances of encountering dolostone reservoirs with good reservoir properties. Although dolostones make excellent reservoirs in favourable cases, its prediction has not yet been achieved, as it is the most challenging diagenetic process to ...

Topographic effects on magnetotelluric responses may be severe on rugged terrains. Finite elements simulation is a valuable tool to quantify this effect, due to its capability to match real morphologies. To do the estimate of the distortion, the AC/DC Module of COMSOL has been employed, using a model of homogeneous resistivity on which a DEM (Digital Elevation Model) profile of the Deep Freeze ...

The percolation of water into soil can be modeled considering Darcy's Law in laminar flow. In this manner the key property is the coefficient of hydraulic conductivity. Its determination can be made through laboratory or field testing. One of the most known field tests used for determination of this property is the Slug Test. This test consists of a perforated well in the ground where a known ...

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 investigate the temperature gradient developed in the cap rock. Ultimately, results from this study will lead to an ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

Temperature measurements of the subsurface are available due to hydrocarbon exploration in the project area, where the average drilling depth is about 2-4 km and the deepest well reaches about 8.5 km. Since the data is heavily uneven distributed, standard interpolation techniques did not deliver satisfying results. This is why numerical modeling was applied to assess the thermal regime of the ...

New geothermal energy sources hold promise for the future. Deep submarine geothermal energy related to hydrothermal vents is emerging in many places along the oceanic spreading centers. Shallow submarine geothermal systems are found near to continental platforms. We present the initial development of mathematical models to simulate the energy transport in submarine systems. A model for the ...
