Each oil and gas field at certain stage of development is characterized by variety of geological and geophysical studies and by the quantity and quality of available information. Also depending on the development stage geological objectives strongly differ. For example, a bluefield project starts with a completely undeveloped area and the main objectives of this stage are field discovery and ballpark reserves estimation. Obtaining lateral reservoir distribution from seismic data is usually done at the greenfield stage. A brownfield project requires a detailed 3D reservoir model of a target interval. Additional details are critical when building geological and hydrodynamic models or planning production well patterns. Usually, a reservoir model is significantly more complicated at the brownfield than at the bluefield stage. The efficiency of geostatistical inversion for risk assessment is presented in this paper in the form of oil field case study
