Supplementary Data: Bridging Computational Stratigraphy and Reservoir Simulation for Geologically Realistic High-resolution Reservoir Modeling

The two reservoir models in this dataset are part of the supplementary material of the paper “Bridging Computational Stratigraphy and Reservoir Simulation for Geologically Realistic High-resolution Reservoir Modeling” published in SPE Journal. https://doi.org/10.2118/212244-PA.

The model in "CompStratFluvialDeltaicModel.zip" is a sector model (as shown in "CompStratFluvialDeltaicModel.JPG"): - Dimension: 40x40x2801 - DX = DY = 20 m for all cells, DZ varies - Number of defined cells: 4,479,071 - Model properties included: grainsize, porosity, permeability, shale body label, shale sub-body label, score, and class - Latest update: July 15th, 2023 The model in "CompStratFluvialDeltaicModel_Large.zip" is a much larger model (as shown in "CompStratFluvialDeltaicModel_Large.JPG"). The previous sector model is taken from (20,20) to (119, 119). - Dimension: 201x201x2801 - DX = DY = 20 m for all cells, DZ varies - Number of defined cells: 113,090,331 - Model properties included: grainsize - Latest update: July 15th, 2023 The models are shared in three formats: RESQML v2.0.1, Eclipse EGRID, and Eclipse ASCII. Note that the grids in different formats loaded in different software may be mirror-flipped, or the origin location may be different. The “RESQMLv2” folder contains the RESQML files (“.epc” and “.h5” files). Do not change the file names as there may be internal mapping between the “.epc” and “.h5” files. RESQML is an upstream oil and gas data-exchange standard that facilitates reliable, automated exchange of data among software packages used in subsurface workflows, for example for earth and reservoir modeling workflows. https://www.energistics.org/resqml-data-standards The “Eclipse_EGRID” folder contains the “.egrid” file (the model grid) and the “.GRDECL” file (the model properties). The property values of undefined cells are set to -9999. The “Eclipse_ASCII” folder contains four “.GRDECL” files describing the model grid and properties in ASCII format. The property values of undefined cells are set to -9999.
