The use of water production as a pressure mitigation tool in the context of CO₂ storage is widely studied but the impact it might have on the migration behaviour of a buoyant CO₂ plume is less well reported. To investigate this further two different scenarios were modelled. In the first, a single water production well was used to draw CO₂ along the strike of an open aquifer with a regional dip. Large rates of water production (5–10 times the volume of injected CO₂) were required to achieve only small displacements of the CO₂ plume. The second scenario investigated to what extent an induced hydraulic gradient might spill CO₂ already stored in a structural trap. Here the effects were more pronounced with over 90% of the CO₂ being spilled at a water cycling rate of 10 Mt per year (corresponding to a hydraulic gradient of 1.28 bar/km). The modelling was tested by the real case at Sleipner where CO₂ migration in the Utsira Sand is potentially impacted by water production at the nearby Volve field. Simulations concluded that the CO₂ plume at Sleipner should not be materially affected by water production from Volve and this is supported by the time-lapse seismics.

广泛研究了在CO ₂储存的情况下使用水生产作为压力缓解工具，但是鲜有报道其可能对浮力的CO ₂羽流的迁移行为产生影响。为了对此进行进一步研究，对两种不同的情况进行了建模。首先，使用单个产水井沿具有局部倾角的裸露含水层走向吸取CO ₂。为了仅实现小体积的CO ₂羽流，就需要高的产水率（所注入的CO ₂体积的5-10倍）。第二种情况调查了诱导的水力梯度可能在多大程度上溢出CO ₂已经存储在结构陷阱中。这里的影响更为明显，每年有10 Mt的水循环速率（对应于1.28 bar / km的水力梯度）溢出90％以上的CO ₂。该模型已在Sleipner的实际案例中进行了测试，在该案例中，Utsira沙中的CO ₂迁移可能受到附近Volve油田产水的影响。模拟得出的结论是，Sleipner的CO ₂羽流不应受到Volve产水的实质影响，而延时地震则可以证明这一点。
