威德福國際公司周四報道稱，該公司已與埃尼公司簽署了一份為期四年的獨家合同，為其提供配備無線電頻率識別的井下套管隔離閥。

威德福在發給鉆井的電子郵件中指出，該合同要求在關鍵的埃尼井中部署至少30個無臍帶井下部署閥(NU-DDV)。

威德福鉆井、評估和干預部門總裁Dean Bell表示:“該合同與威瑟福德和埃尼公司從開始到結束鉆井和完井過程中持續改善作業安全和環境性能的努力是一致的。”

威德福表示，在管理壓力鉆井(MPD)和欠平衡鉆井(UBD)應用中，配備射頻識別設備(RFID)的閥門通過在起下鉆過程中機械地將儲層與地面隔離，從而提高了過程安全性，并且無需壓井。此外，該公司還聲稱，這種閥門減少了外部控制線和夾緊操作，縮短了安裝時間，將人員從紅區撤離，消除了抽油效果，并縮短了脫扣時間，從而提高了系統的可靠性。

貝爾繼續說道:“該獎項是與埃尼公司兩年研發合作的成果，該公司推出了一款帶RFID的井下套管隔離閥。”“我們的目標是開發一種創新的解決方案，能夠提供一種獨立的井下安全防護層，作為現有常規防護層的補充，確保在下鉆時控制不合理的地層涌入。”

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.”
