Abstract

Field N is situated in Yamal peninsula in Western Siberia. From 19 productive layers, J3-4 layers are the most important for consideration as they contain significant amount of STOIIP. On base of complex analysis of core data and paleogeography, depositional environment of J3-4 layers was defined as tide dominated delta. Sandbodies are presented by channel facies and also by interdistributary facies, formed by levees and crevasse splays. Qualitative and quantitative analysis of log data allowed creation of input data for geological model. 3D facies model was obtained using combination of object modeling and sequential indicator simulator methods. Properties in model were obtained with use of random simulation function and various recalculations. Geological model was transformed into simulation model. Uncertainties, related to sandbody dimensions, model realizations and sandbody distribution in tested well were evaluated using numerous realizations of geomodel. Cumulative oil recovery and rates were evaluated for horizontal and vertical wells, using P10 P50 P90 values.
