| 摘要 |
In some embodiments, an apparatus and a system, as well as a method and an article, may operate to activate a thermal source in a borehole to heat a portion of a geological formation proximate to the borehole, to move the thermal source or thermal receivers within the borehole (to reduce the distance between the location of heating by the thermal source and one or more of the thermal receivers), to receive signals from one or more of the thermal receivers, responsive to activation of the thermal source, wherein the moving serves to reduce a time between heating the location and the receiving, and processing the signals, distance information related to the moving, and time of the receiving to determine a thermal property of the geological formation. Additional apparatus, systems, and methods are described. |
