ABSTRACT:
The present invention relates to methods and apparatus for making in situ thermal property determinations utilizing a heat source employed in wellbore stabilization procedures, well drilling, or well perforating, for example. In particular, using a heat source, such as a laser driller, to enable formation temperature measurements. Based on these measurements, thermal properties of the formation may be inferred.
