Stratigraphic Surfaces Database.

This database stores down-hole stratigraphic data to complement the seismic surface picks stored in the Seismic Locations And Sections Database (LOCSEC). Because these surfaces are chosen for their visibility on seismic data, they may not be directly equivalent to established BGS lithostratigraphic and/or choronstratigraphic divisions. However, the local coding system is based on and can relate to the BGS stratigraphic LEXICON. Stratigraphic picks are stored in terms of depth and seismic one-way travel time. Local borehole summary information (location, elevation, etc.) is used because both onshore and offshore boreholes are stored in this database. These data can be related to the BGS onshore borehole database by borehole registration, and to the offshore well database by DTI well-id. Additional tables (under development) provide information on hydrocarbon tests and their results. Almost all data are within the UK Onshore area; although there are some UK near-shore and offshore (North Sea, Irish Sea).

本数据库存储了井下地层学数据，以补充存储在地震位置与剖面数据库（LOCSEC）中的地震地表拾取信息。鉴于这些地表系根据其在地震数据中的可见性被选取，它们可能并不完全等同于已确立的英国地质调查局（BGS）的地层学和/或年代地层学划分。然而，本地的编码系统基于并能够与BGS的地层学词汇表相对应。地层学拾取以深度和地震单程旅行时间作为存储参数。由于本数据库中存储了陆地和海上钻探孔数据，因此使用本地钻孔概要信息（位置、海拔等）。这些数据可通过钻孔注册与BGS陆地钻孔数据库相关联，并通过DTI井标识符与海上井数据库相关联。正在开发中的附加表格提供了有关烃类测试及其结果的信息。几乎所有数据均位于英国陆地区域；尽管其中包含一些英国近海和海上区域（北海、爱尔兰海）。
