21st Century Exploration RoadMap (21CXRM) Palaeozoic Petroleum Systems Analysis Project Products

Reports, images, GIS and gridded products describing the Palaeozoic geology and conventional petroleum systems of parts of the UK offshore. 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 datasets are applicable for use at scales between 1: 750,000 to 1: 3,000,000.

本数据集包括报告、图像、地理信息系统（GIS）和网格化产品，旨在描述英国近海部分地区的新生代地质构造和传统石油系统。本研究重点聚焦于北海中部高地、中央北海、莫雷湾和奥克尼盆地周边的泥盆纪和石炭纪岩石，并在爱尔兰海广大区域对石炭纪岩石进行了描述。经同行评审的产品由英国地质调查局（BGS）为英国能源与气候变化部（DECC）/油气管理局（OGA）、油气英国和石油公司赞助商于2014年11月至2016年5月期间，为21CXRM新生代项目所制作，旨在提升区域数字化数据集的质量，增进对未充分勘探的新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广泛井、地震、重力磁力和源岩数据集的新解释，并与岩性学研究、盆地模拟以及英国陆上地质知识相结合。发布的数据进行了整理和解读，未经发布的数据解读在数据所有者同意的情况下予以包含。未发布原始数据以及2016年发布的英国政府地震数据被排除在外。该数据集适用于1:750,000至1:3,000,000的比例尺范围内使用。
