Presented work is motivated by pre-realization phase of rock heating experiment in underground, testing properties for cyclic energy storage. Heating unit, installed in large borehole from end of a tunnel, is fixed to the rock face with the geo-polymer. Rest of the borehole is filled with isolation material. We used the Heat Transfer Module and the Structural Mechanics Module in COMSOL for ...

There are only two types of naturally-occurring earthquakes anywhere on the Earth: 1) those associated with the dynamics of plate tectonics and 2) those associated with the dynamics of the hydrologic cycle. The first type is characteristic of an INTERplate setting (like the San Andreas Fault). The second (“hydroseismicity”) is characteristic of an INTRAplate setting (like the Virginia ...

Electric well logging was the first logging method used below ground in boreholes by the petroleum industry. Of all the rock parameters measured by logging tools, the electrical resistivity is of particular importance. Resistivity measurements are essential for determining the relative amount of hydrocarbons in a formation.

Volcanic margins are characterized by excessive magmatic activity. One of the most studied volcanic margins is the Vøring margin, offshore mid-Norway. The large volumes of magmatic rocks found there are believed to have been produced by the melting of an abnormally hot mantle. We use COMSOL Multiphysics to investigate the hypothesis that the source of this thermal anomaly was a mantle ...

We developed a new numerical model able to predict the critical oil rate for which oil-producing wells can be invaded by geothermal brine. The model is a single nonlinear partial differential equation (PDE) which depends only on water saturation. This PDE is a 3D-generalization of the classical 1D-Buckley-Leverett model. To solve this model, we used Lagrange-quadratic finite elements into the ...

A lot of techniques are developed to treat soils polluted by hydrocarbons pollutants: incineration, thermal treatment, extraction, chemical oxidation, bioremediation… Some of these techniques are very energy consuming (incineration, thermal treatment…) and often need a subsequent treatment of the generated gases or liquids. Of all the decontamination methods, bioremediation appears to be the ...

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 ...

Bioventing (BV) is a popular in situ technology for the treatment of petroleum hydrocarbon contaminated soil. Generally, the process involves the stimulation of the native microorganisms by adding nutrients and oxygen to the contaminated soil in the vadose zone. BV can address tailing, where ineffective treatment through mass transfer limitations keeps the contamination level above the regulatory ...

Thermal anomalies indicating elevated temperatures often are present in producing hydrocarbon fields. This paper discusses precision temperature logs obtained over a salt dome in the Bayou Bleu hydrocarbon field in southwest Lousiana, and presents a 3-D thermal-fluid model of the dome constrained by these types of logs. The numerical model in which both an enhanced thermal conductivity ...

Ensuring the quality of underground water and controlling its quantity is of major concern for the population. Therefore, this subject attracts many students from different specialties at different levels of their curriculum. In fact, the pedagogic objectives of the course may be different according to the level or/and interest of the students and COMSOL is used due to its versatility. In this ...
