威德福公司与埃尼集团签订了为期四年的合同

威德福国际公司周四报道称，该公司已与埃尼公司签署了一份为期四年的独家合同，为其提供配备无线电频率识别的井下套管隔离阀。

威德福在发给钻井的电子邮件中指出，该合同要求在关键的埃尼井中部署至少30个无脐带井下部署阀(NU-DDV)。

威德福钻井、评估和干预部门总裁Dean Bell表示:“该合同与威瑟福德和埃尼公司从开始到结束钻井和完井过程中持续改善作业安全和环境性能的努力是一致的。”

威德福表示，在管理压力钻井(MPD)和欠平衡钻井(UBD)应用中，配备射频识别设备(RFID)的阀门通过在起下钻过程中机械地将储层与地面隔离，从而提高了过程安全性，并且无需压井。此外，该公司还声称，这种阀门减少了外部控制线和夹紧操作，缩短了安装时间，将人员从红区撤离，消除了抽油效果，并缩短了脱扣时间，从而提高了系统的可靠性。

贝尔继续说道:“该奖项是与埃尼公司两年研发合作的成果，该公司推出了一款带RFID的井下套管隔离阀。”“我们的目标是开发一种创新的解决方案，能够提供一种独立的井下安全防护层，作为现有常规防护层的补充，确保在下钻时控制不合理的地层涌入。”

Weatherford Secures Four-year Eni Contract

Weatherford International reported Thursday that it has signed an exclusive four-year contract with Eni S.p.A. for radio frequency identification-equipped downhole casing isolation valves.

The contract calls for at least 30 Non-Umbilical Downhole Deployment Valves (NU-DDV) that will be deployed in critical Eni wells, Weatherford noted in a written statement emailed to Rigzone.

“This contract aligns with both the Weatherford and Eni pursuit of continuous improvement in operational safety and environmental performance across the start-to-finish drilling and completion process,” remarked Dean Bell, Weatherford’s president for drilling, evaluation and intervention.

Deployed during managed pressure drilling (MPD) and underbalanced drilling (UBD) applications, the radio frequency identification device (RFID)-enabled valve enhances process safety by mechanically isolating the surface from the reservoir during tripping and eliminates the need to kill the well, Weatherford stated. Also, the company contends the valve boosts system reliability by eliminating external control line and clamping operations, cuts installation time, removes personnel from the red zone, eliminates swabbing effects and reduces tripping time.

“This award is the result of two years of research and development collaboration with Eni to launch a downhole casing isolation valve with RFID,” continued Bell. “The goal was to develop an innovative solution capable of providing an independent downhole safety barrier to supplement the conventional barriers already in place, assuring control of unwarranted formation influx while tripping.”
