Geomodel preschool1/8/2023 The proposed approach of estimation allows make stochastic estimation of reserves and following economic assessments of projects before high-cost exploration program, which is necessary for decreasing geological uncertainty of target objects. Algorithm of fast estimation the following important stages: a) identification and estimation of effective area, where potential objects might be formed b) identification possible number of separated reservoir bodies c) estimation of volume of hydrocarbon in place of 1 geological object and total volume of reserves. Developed fast-method including object geological modeling for assessment of lateral distribution of reservoir, level of heterogeneity and potential gross reservoir volume allowed team to estimate volume of hydrocarbon in place correctly using geological success. For evaluated areas with poor volume of geological and geophysical data new approach was developed and tested based on the available tectonic models, paleogeographic conditions and stochastic modeling. ![]() In general, these areas are located in the regions with absence of infrastructure, which impact on expenditure of the following exploration program. Low level of available data set is the main reason of such problems. ![]() Many petroleum companies have problems associated with absence of necessary information during the geological and economic assessment.
