UK England onshore petroleum unlicensed blocks (WGS84)

<p>UKCS onshore petroleum unlicensed blocks in WGS84 (EPSG: 4326)</p><p>A Licence is a geographically defined area for prospecting, exploration or extraction of petroleum resources.&nbsp;</p><p>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 /><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 /><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).</p><p>The NSTA has discretion in the granting of licences to help maximise the economic recovery of the UK's oil and gas resources.<br /><br />Licence data is represented by 3 different datasets;&nbsp;</p><ol><li>Licence.<ul><li>Licence polygons represent the whole licence and have one polygon per licence.</li></ul></li><li>Licence Blocks.<ul><li>Licenced Blocks and Sub areas represent finer divisions of these licences and may have many polygons per licence.</li></ul></li><li>Sub Areas.<ul><li>Most Licenced Blocks are split with several sub areas, sometimes with differing operators and beneficiaries.</li></ul></li></ol>采用WGS84（EPSG: 4326）坐标系的英国大陆架（UK Continental Shelf，简称UKCS）陆上石油未许可区块 许可是指经地理划定、用于石油资源勘查、勘探或开采的区域。 北海过渡管理局（North Sea Transition Authority，简称NSTA）的许可体系覆盖大不列颠境内、其领海以及英国大陆架（UKCS）范围内的油气资源。 《1998年石油法》将英国境内所有石油资源的权属划归王室，但NSTA可核发许可，赋予持证人"搜索、钻探并开采"石油的专属权利。 许可分为多个类别，核心区分维度包括陆上与海上许可，以及仅覆盖勘探活动的勘探许可与同时覆盖勘探和开采活动的生产许可。 NSTA在许可核发过程中拥有裁量权，以最大化英国油气资源的经济采收率。 许可相关数据分为三类数据集： 1. 许可整体数据： - 许可多边形代表完整许可区块，每个许可对应一个多边形。 2. 许可区块数据： - 许可区块与子区域为许可的更精细划分单元，单个许可可对应多个多边形。 3. 子区域数据： - 多数许可区块会被划分为若干子区域，不同子区域可能对应不同的作业方与收益方。
