21st Century Exploration RoadMap (21CXRM) Palaeozoic Petroleum Systems Analysis Project: Overview Regional Structural, Palaeogeography and Poster Products

GIS versions of a regional structural summary and palaeogeographic reconstructions describing the Palaeozoic geology of parts of the UK offshore and onshore, plus a set of summary posters and a summary presentation capturing the conventional petroleum systems. Devonian and Carboniferous rocks are the focus in and around the Mid North Sea High, Central North Sea, the Moray Firth and Orcadian Basin. In the greater Irish Sea area, Carboniferous rocks are described. The peer-reviewed products were produced for the 21CXRM Palaeozoic Project by BGS for DECC/OGA, Oil and Gas UK and oil company sponsors between November 2014 and May 2016, to improve regional digital datasets and knowledge of the underexplored Palaeozoic petroleum systems, and to stimulate exploration. The petroleum systems analysis was based on new interpretations of extensive well, seismic, gravity-magnetic and source rock datasets, integrated with petrophysical studies, basin modelling and UK onshore knowledge. Released data were collated and interpreted, and interpretations of unreleased data were included with agreement of the data owners. Unreleased raw data is excluded, as is the UK Government Seismic data released in 2016. The GIS layers were digitised from figures prepared for project reports and are applicable for use at scales between 1:1,000,000 and 1:3,000,000.

本数据集包括对英国海上及陆上部分地区古生代地质的GIS版本区域结构概要和古地理重建，以及一套总结海报和总结演示文稿，旨在捕捉常规石油系统。重点研究区域包括北海中部高地、中央北海、莫雷湾和奥克尼盆地及其周边的志留纪和石炭纪岩石。在更广阔的爱尔兰海区域，描述了石炭纪岩石。这些经过同行评审的产品由英国地质调查局（BGS）为DECC/OGA、石油和天然气UK以及石油公司赞助商，于2014年11月至2016年5月间为21CXRM古生代项目制作，旨在提升区域数字化数据集和未充分勘探的古生代石油系统的认知，并激发勘探活动。石油系统分析基于对大量井、地震、重力磁力和源岩数据集的新解释，并与岩石物理研究、盆地建模以及英国陆上知识相结合。发布的数据进行了整理和解释，未发布数据的解释在数据所有者同意下包含其中。未发布原始数据被排除在外，2016年发布的英国政府地震数据也不例外。GIS图层是从为项目报告准备的图表中数字化而来，适用于1:1,000,000至1:3,000,000的比例尺使用。
