Johan Sverdrup 油田永久油藏监测 (PRM) 系统现已记录了两项调查，记录了自 2019 年 10 月开始生产和注入以来注水的进展情况，揭示了与水饱和度增加相关的清晰 4D 信号。4D 信号已用于帮助指导油藏模型内的更新，从而更好地了解油田开发的进展情况。
2010 年，在斯塔万格以西约 150 公里处的北海发现了巨型 Johan Sverdrup 油田。该油田横向范围广泛，覆盖 200 km 2，主要由浅浮雕结构的上侏罗统 Draupne 内砂岩和上三叠统 - 下侏罗统 Statfjord 砂岩组成。该储层具有优异的孔隙度和渗透率，钻杆测试显示渗透率高达 70 达西，长距离和跨断层连通良好。
The Johan Sverdrup field permanent reservoir monitoring (PRM) system now has recorded two surveys documenting the progression of the waterflood since production and injection began in October 2019, revealing a clear 4D signal linked to the increase in water saturation. The 4D signals have been used to help guide updates within the reservoir model, providing a better understanding of how the field development is progressing.
The giant Johan Sverdrup oil field was discovered in 2010 in the North Sea approximately 150 km west of Stavanger. The field is laterally extensive, covering 200 km2 and consisting primarily of Upper Jurassic intra-Draupne sandstone and Upper Triassic-Lower Jurassic Statfjord sandstones in a low relief structure. The reservoir is characterized by excellent porosity and permeability, with drillstem tests showing permeabilities of up to 70 darcies with good communication over long distances and across faults.
