Advanced Determination of Heat Flow Density on an Example of a West Russian Oil Field

Reliable geothermal data are required for basin and petroleum system modeling. The essential shortcomings of the methods results previous investigations lead to a necessity reappraise on thermal properties heat flow. A new, advanced experimental basis was used provide reliable vertical variations in formation flow area surrounding prospecting borehole drilled through an unconventional hydrocarbon reservoir Domanik Formation Orenburg region (Russia). Temperature logging conducted 12.5 months after well drilling. rocks were measured with continuous core profiling all 1699 recovered samples. Within non-cored intervals, conductivity determined from well-logging data. influence aging, multiscale heterogeneity anisotropy, situ pressure temperature rock accounted for. terrestrial be 72.6 ± 2.2 mW·m−2—~114% larger than published average studied area. experiment presents first experience supporting modeling plays investigations.
