Interactive CNS Pressure Cells Map

<p>HPHT fields in the North Sea account for a significant
portion of UK total production. Expediting the successful exploitation of new
HPHT structures in the UKCS can play a major role in maximising economic
recovery and extending the asset life of existing infrastructure. While HPHT
conditions are recorded in a number of UKCS basins, by far the largest resource
attributable to HPHT producing fields, discoveries, and mature prospects lies
within the Central Graben. </p>

<p>The shapefiles in this dataset represent a pressure cell
summary for Jurassic and Triassic in the Central North Sea, generated by the
NSTA and based on a pressure dataset incorporating 194 wells. The pressure
dataset was generated from released well data in the NDR by Ikon Science and is
published separately on the Open Data Site. The pressure data includes
formation pressure and overpressure and is categorised by fluid type, test
type/quality, and stratigraphy. Aquifer overpressure is derived for many wells,
with an uncertainty range applied where hydrocarbon water contact or structural
spill is uncertain. Pressure cells are interpreted by the NSTA on the basis of
the aquifer overpressures and most likely pressure cell boundaries derived from
literature and industry reports. This study combines well pressure data with
historic and published structural interpretations to generate a pressure cell
map for the pre-Cretaceous strata of the UK Central North Sea. </p>

北海的高压高温（HPHT）油田构成了英国总产量的重要部分。加速在英国大陆架（UKCS）成功开发新的HPHT结构，对于最大化经济回收和延长现有基础设施的使用寿命发挥着至关重要的作用。尽管在英国大陆架的多个盆地中都有记录HPHT条件，但归属于HPHT生产油田、发现和成熟前景的资源量，绝大多数集中在中央断陷带。本数据集中的Shapefile代表中央北海侏罗系和三叠系的压力单元概要，由NSTA生成，并基于包含194口井的压力数据集。该压力数据集由Ikon Science根据NDR中发布的井数据生成，并在Open Data Site上单独发布。压力数据包括地层压力和超压，并按流体类型、测试类型/质量以及地层划分。对于许多井，根据碳氢水接触或构造溢出不确定的情况，计算了含水层超压的不确定性范围。压力单元由NSTA根据含水层超压以及从文献和行业报告中得出的最可能的压力单元边界进行解释。本研究将井压力数据与历史和已发表的构造解释相结合，生成了英国中央北海前侏罗系地层压力单元图。
