UKCS Licensed Blocks ED50

A Licence is a geographically defined area for prospecting, exploration or extraction of petroleum resources. The North Sea Transition Authority’s licensing system covers oil and gas within Great Britain, its territorial sea and on the UK Continental Shelf (UKCS).<br />The Petroleum Act 1998 vests all rights to the nation’s petroleum resources in the Crown, but the NSTA can grant licences that confer exclusive rights to ‘search and bore for and get’ petroleum.<br />Licences fall into several categories. The principal distinctions are between onshore and offshore licences, and between exploration licences (which cover exploration alone) and production licences (which cover both exploration and production). The NSTA has discretion in the granting of licences to help maximise the economic recovery of the UK’s oil and gas resources.<br />Licence data is represented by 3 different datasets; Licences, Licence Blocks and Sub Areas. Licence polygons represent the whole licence and have one polygon per licence. Licenced Blocks and Sub areas represent finer divisions of these licences and may have many polygons per licence. Most Licenced Blocks are split with several sub areas, sometimes with differing operators and beneficiaries.

许可，即指特定地理范围内的石油资源勘探、开发或开采区域。北海过渡管理局的许可体系涵盖了英国境内、其领海以及英国大陆架（UKCS）内的石油和天然气资源。根据1998年石油法，国家石油资源的所有权利归王室所有，但北海过渡管理局有权颁发许可，赋予‘搜寻、钻探和获取’石油的专有权利。许可分为多个类别，主要区别在于陆上许可与海上许可，以及仅涵盖勘探的勘探许可和涵盖勘探与生产的开采许可之间的区别。在许可的颁发过程中，北海过渡管理局具有裁量权，以最大限度地提高英国石油和天然气资源的经济效益。许可数据由三个不同的数据集表示；许可、许可区块和子区域。许可多边形代表整个许可区域，每个许可对应一个多边形。许可区块和子区域代表许可的更细粒度划分，每个许可可能包含多个多边形。大多数许可区块都分割成多个子区域，有时涉及不同的运营商和受益人。
