- build ECLIPSE simulation models directly from your geological models; - add fluid properties, well completions, production history and event scheduling. - Organize your geological realizations and development scenarios into cases - select and launch the appropriate ECLIPSE - Frontsim simulator - analyze your results Multi-trace seismic attributes - Generation of advanced seismic attributes from imported seismic volumes (e.g. graphic equalizer, structural smoothing, variance, Iso-frequency, iso frequency, t*attenuation, Ant-tracking). Seismic volume rendering and extraction -3D seismic attribute volume can be extracted from a SEG-Y/ZGY cube - Apply different degrees of transparency . - Render seismic volume in 3D and - visualize together with any other data available in Petrel Geobody interpretation - Use State-of-the-art volume blending technology to quickly isolate, extract, and integrate a body directly into a property model for true 3D volume interpretation. - interactively blend multiple seismic volumes - isolate areas of interest -instantly extract those areas into a 3D object called a geobody. Seismic sampling - Display of seismic data (using intersections) - QC of the seismic data within a 3D grid - depth conversion of a seismic volume (requires the Domain Conversion module) - creating a seismic property by sampling any seismic attribute into a 3D grid -extract seismic data to an attribute map that can be draped over a surface. Domain conversion -Node by node depth conversion of the structural 3D grid -Average velocity for selected zones are used based on constants, linear velocity functions, velocity maps or a combination of these, depth conversion along pillars or vertically, spreadsheet report Automated structural interpretation:-Automated fault interpretation workflow. - Need to understand the trends of fault surfaces. - spend time and to make correlations from automatically extracted fault patches from Petrel-generated Ant tracking cubes.
