Hydrogeology of the vicinity of Homestake mine, South Dakota, USA

In an attempt to understand the numerous physical aspects of mines, a numerical modeling simulation on the development and dewatering of mines has been presented. The transient line source was used to complete this task. The log approximation was used to find the change in flow rate per unit length of the tunnel....

When rocks get hot: thermal properties of reservoir rocks

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 paper reviews the thermal conductivities of reservoir rocks by analyzing data collected from performing the transient line ...

Use of a Pre-Drilled Hole for Implementing Thermal Needle Probe Method for Soils and Rocks

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, as the process of inserting the probe can disturb the surrounding sample or damage the equipment. This article investigates the effects of drilling a hole ...

Temperature dependence of the thermal diffusivity of sandstone 

High temperatures play a crucial role in the deterioration of the thermal properties of rocks and can threaten the structural integrity of many applications in engineering. This research focused on the variations in thermal diffusivity of sandstone after high temperature heating. Thermal properties of the samples were measured before and after heating using a thermal constants analyzer based on the Transient Plane Source (TPS) technique. Thermal diffusivity of the sandstone ...

Measurements of thermal properties of rock samples under high temperature conditions

This study looked to analyze temperature effects on thermal transport properties of dry granite, gabbro, marble, and sandstone samples. An instrument was used with a high temperature chamber to perform thermal conductivity measurements on the rock samples. The thermal conductivity of the granite, marble, and sandstone samples were found to decrease with increasing ambient temperature, while the gabbro remained almost constant....
