GeoStrat Jurassic Report (ArcGIS Version)

<p><b>Geostrat Report – The Sequence Stratigraphy and Sandstone Play Fairways of the Late Jurassic Humber Group of the UK Central Graben</b></p> <p></p> <p>This non-exclusive report was purchased by the OGA from Geostrat as part of the Data Purchase tender process (TRN097012017) that was carried out during Q1 2017. The contents do not necessarily reflect the technical view of the OGA but the report is being published in the interests of making additional sources of data and interpretation available for use by the wider industry and academic communities.</p> <p></p> <p>The Geostrat report provides stratigraphic analyses and interpretations of data from the Late Jurassic to Early Cretaceous Humber Group across the UK Central Graben and includes a series of depositional sequence maps for eight stratigraphic intervals. Stratigraphic interpretations and tops from 189 wells (up to Release 91) are also included in the report.</p> <p></p> <p>The outputs as published here include a full PDF report, ODM/IC .dat format sequence maps, and all stratigraphic tops (lithostratigraphy, ages, sequence stratigraphy) in .csv format (for import into different interpretation platforms).</p> <p></p> <p>In addition, the OGA has undertaken to provide the well tops, stratigraphic interpretations and sequence maps in an ESRI ArcGIS format that is intended to facilitate the integration of these data into projects and data storage systems held by individual organisations. As part of this process, the Geostrat well names have been matched as far as possible to the OGA well names from the OGA Offshore Wells shapefile (as provided on the OGA’s Open Data website) and the original polygon files have been incorporated into an ArcGIS project. All the files within the GIS folder of this delivery have been created by the OGA. OGA web feature services (WFSs) have been included in the map document in this delivery. They replace the use of a shapefile or feature class to represent block, licence and quadrant data. By using a WFS, the data is automatically updated when it becomes available via the OGA.</p> <p></p> <p>A version of this delivery containing shapefiles for well tops, stratigraphic interpretations and sequence maps is available on the OGA’s Open Data website for use in other GIS software packages.</p> <p></p> <p>All releases included in the Data Purchase tender process that have been made openly available are summarised in a mapping application available from the OGA website. The application includes an area of interest outline for each of the products and an overview of which wellbores have been included in the products.</p><b>Geostrat报告——英国中央地堑晚侏罗世亨伯组层序地层与砂岩勘探有利区带</b> 本非独家报告由英国油气管理局（Oil and Gas Authority, OGA）于2017年第一季度开展的数据采购招标流程（TRN097012017）中从Geostrat处购得。本报告内容未必代表OGA的技术观点，发布该报告旨在为全行业及学术团体提供更多的数据与解释资料来源。 本次Geostrat报告针对英国中央地堑内晚侏罗世至早白垩世亨伯组开展地层分析与数据解译，包含8个地层区间的沉积层序图系列。报告同时纳入了截至第91版发布的189口探井的地层解译结果与地层顶界数据。 本次发布的成果包含完整PDF版报告、ODM/IC格式的.dat层序图件，以及以.csv格式存储的全部地层顶界数据（涵盖岩石地层学、年代学及层序地层学信息，可导入各类解译平台）。 此外，OGA承诺将以ESRI ArcGIS格式提供井顶界数据、地层解译结果与层序图件，以方便各机构将此类数据集成至自身项目与数据存储系统中。在此流程中，Geostrat井名已尽可能与OGA公开数据网站提供的《OGA近海井件形状文件（shapefile）》中的OGA井名完成匹配，原始多边形文件已整合至ArcGIS项目中。本次交付的GIS文件夹内所有文件均由OGA创建。本次交付的地图文档中已集成OGA网络要素服务（Web Feature Services, WFSs），以替代使用形状文件（shapefile）或要素类来表示区块、许可证及象限数据。通过使用WFS，相关数据可在OGA发布更新时自动同步更新。 本次交付的另一版本包含用于井顶界数据、地层解译结果与层序图件的形状文件（shapefile），可在OGA公开数据网站下载，供其他GIS软件使用。 OGA官网提供的制图应用已汇总了本次数据采购招标流程中所有公开发布的成果。该应用可为每项产品提供研究范围轮廓图，并概述各产品纳入的钻井眼信息。
