Application of the statistical reverse method for the lithological analysis of bituminous deposits

The studied deposit is located on the territory of Republic Tatarstan (Russia). reservoir formation represented by bituminous sandstone. being developed steam-gravity drainage (SAGD). researchers noted that has variability petrophysical parameters in thickness. correct adjustment lithological model will allow us to assess characteristics its thickness, which can better predict and elastic properties. article presents results modeling mineralogical composition rocks coefficient total porosity. Results received using statistical reverse method constructing a volume model. This based geophysical well logging used content rock-forming components sediments. use core data, particular X-ray phase analysis, made it possible evaluate
