When attempting to extract reservoir fluid from rock, the rock is often heated. When the reservoir fluid is hotter it is less viscous and easier to extract. Knowing the thermal conductivity of the rock in question is therefore incredibly important to preform these procedures. This ...
The transient line source probe needle has become a very common tool for measuring the thermal conductivities of soils and some rocks. However, field measurements using this technique can be difficult with densely packed soil and rock, ...
The purpose of this study was to look at the effective thermal conductivity (ETC) of coking coal, sandstone and foamed concrete existing in extreme thermal environments. Thermal-physical properties were measured under various conditions: fully water saturated, after saturation during air-drying, and oven-drying at 105°C. Results ...
A comparative study was conducted on the properties of lightweight cementitious composites (LWCCs) mixed with four types of filler particles; EPS beads, dry-expanded plastic microspheres, hollow glass microspheres, and fly ash cenospheres. Thermal conductivity was tested using the transient plane source method. Results showed that ...
This paper summarizes the measuring method of thermal conductivity of rocks and the parameters controlling the transport and exchange of thermal energy. The transient plane source method was analyzed and found to have advantages over other methods, such as short test times and the ability ...
