Beta 油田于 1964 年发现，位于尼日尔三角洲沉积盆地，由 25 个堆叠的含油气储层组成，海底真实垂直深度 (TVDSS) 位于 5,500 至 12,000 英尺之间。油田启动后不久，石油产量就达到了 8,900 STB/D 的峰值，之后一直在下降。该油田规划了 Beta 7 和 Beta 8 两口水平井，但计划井的产量预测显示出潜在的早期见水和高含水。自主流入控制装置 (AICD) 在 Beta 油田成功部署，旨在最大限度地减少产水量和最大限度地提高石油采收率。
经过历史匹配后，对两口新水平井进行了模拟，以利用含油饱和度、孔隙度和渗透率限制以及到油/水界面（OWC）的距离的约束来瞄准油藏中的最佳点。然后，使用历史匹配模型来预测新井的产量概况，目标液体产量为 2,000 STB/D。不控流入的产量预测显示，新井在投产第一个月就见水，投产后3个月就达到45%。随后对 Beta-7 和 Beta-8 水平井的旋风 AICD 完井进行了模拟，结果显示石油产量有所提高，产水量有所延迟。
Beta油田选择旋风式AICD应用，以提高生产性能。
Discovered in 1964, the Beta Field in the Niger Delta sedimentary basin consists of 25 stacked hydrocarbon-bearing reservoirs between 5,500 and 12,000 ft true vertical depth subsea (TVDSS). Oil production peaked at 8,900 STB/D shortly after field startup and has been on the decline. Two horizontal wells, Beta 7 and Beta 8, were planned in the field, but a production forecast of the planned wells showed potential early water breakthrough and high water cut. Autonomous inflow control devices (AICDs) were deployed successfully in the Beta Field for the purpose of minimizing water production and maximizing oil recovery.
After history matching, the two new horizontal wells were simulated to target the sweet spots in the reservoir using constraints of oil saturation, porosity and permeability limits, and distance to the oil/water contact (OWC). The history-matched model was then used in forecasting the production profile for the new wells using a target liquid production rate of 2,000 STB/D. The production forecast without inflow control showed water breakthrough in the new wells within the first month of production, reaching to 45% within 3 months of production. Cyclonic AICD completions then were simulated for Beta-7 and Beta-8 horizontal wells, which showed improved oil production and delayed water production.
Cyclonic AICDs were selected for application in the Beta Field to improve production performance.
