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 ...
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 ...
Aqueous foams with densities from 0.03 to 0.2 g/cm3 were studied for their thermal conductivity. It is important to determine an aqueous foam's thermal response because it is often used as a geothermal drilling fluid. In this paper, both helium and nitrogen foams were used each with a different bubble size range. The data was collected using transient line source probe ...
A report based on thermal conductivity measurements of samples from 53 of the first 80 ocean drilling project legs. The data was collected, shipboard by collecting the core samples, then pushing a transient line source probe through the core into the soft sediments. The temperature-time response of this technique gives a two-dimensional value for a plane perpendicular to the needle axis. Corrections are made ...
This article describes an attempt to modify the transient line source probe to be useful in making in-situ measurements in the field. The field of construction, as well as many others would benefit if a new thermal probe could be applied to uncontrolled environments. Three case study buildings have been considered to ascertain the validity and reliability of this new technique in ...
