Abstract From the Canadian patent

Features of subsurface earth reservoirs of interest are made available for analysis by forming three-dimensional, geologic block models (Fig. 4) based on field data. The field data include geological observations such as , lithofacies and porosity values (204) obtained from well data and other sources, as well as geophysical data, usually from seismic surveys. The geologic models representative of subsurface reservoirs so obtained are optimized to match as closely as feasible geologic constraints (116) known or derived from observed geologic data. The models also conform to geophysically based constraints indicated by seismic survey data. The modeled geologic lithofacies and …

Why it's free to use

  • Filed March 13, 1997 and granted April 16, 2002. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 13, 2017.
  • A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 13, 2019.
  • We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
