Abstract

Sensitivity study of hydrodynamic models of heavy oil reservoirs and basin models demonstrated that high quality data on thermal conductivity (TC) and volumetric heat capacity (VHC) for reservoirs and caprocks leads to essential improvement in economic and technological efficiency of heavy oil production and reliability of basin modeling. The new methods and instrumentation developed during the last several years for TC&VHC measurements on cores and core cuttings at bench and formation conditions, allowed to develop the qualitatively new workflow of thermal property investigations. The first stage consists of continuous non-destructive non-contact profiling of TC&VHC on as-received full size cores and cuttings just in core storages with spatial resolution up to 0,5 mm with estimation of thermal anisotropy coefficient. The profiles are used for heterogeneous rock analysis (HRA) and selection of the most representative cores for following measurements at elevated pressure (P) (<200 MPa) and temperature (T) (<300 0C). The TC&VHC measurements at elevated P&T are performed on cores saturated with different fluids with TC tensor components determination. The workflow includes the TC&VHC measurements on core plugs (used for standard petrophysical measurements) saturated with different fluids that provides correlations of TC&VHC with porosity and results in rock matrix TC&VHC required for hydrodynamic and basin modeling. The combination of core plug analysis and P&T measurements data with new theoretical models of thermal properties provides transformation of the TC&VHC profiles to TC&VHC data for rocks saturated with different fluids for elevated P&T. The obtained thermal property data creates representative basis for 4D modeling reservoirs for hydrodynamic and basin modeling, HRA and organic matter content estimation.
