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. Please cite this paper if you use this dataset. Feel free to email the corresponding author if you have questions. - Authors: Boxiao Li, Lewis Li, Xian-Huan Wen, Tao Sun - Affiliation: Chevron Technical Center, Houston, TX, USA - Corresponding author: Boxiao Li; email: boxiao.li at chevron.com The following two synthetic fluvial-deltaic reservoir models are built from Computational Stratigraphy (CompStrat), a state-of-the-art earth-modeling method that captures the key heterogeneities in subsurface reservoirs through modeling of the detailed flow and sediment transportation processes in various depositional environments. 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.

本数据集提供三种格式的模型文件：RESQML v2.0.1、Eclipse EGRID及Eclipse ASCII。需注意：不同软件加载的不同格式网格可能存在镜像翻转，或原点位置存在差异。
- "RESQMLv2"文件夹包含RESQML格式文件（".epc"与".h5"文件）。请勿修改文件名，因".epc"与".h5"文件间存在内部映射关系。RESQML是上游油气行业的数据交换标准，可实现地下油气工作流（如地球与油藏建模工作流）中所用软件包间可靠、自动化的数据交换。相关标准详情可参考：https://www.energistics.org/resqml-data-standards
- "Eclipse_EGRID"文件夹包含".egrid"文件（模型网格）与".GRDECL"文件（模型属性）。无效网格单元的属性值设为-9999。
- "Eclipse_ASCII"文件夹包含四个".GRDECL"格式文件，以ASCII格式描述模型网格与属性。无效网格单元的属性值设为-9999。
