HOUSTON – Weatherford says that it has been awarded an exclusive four-year contract with Eni to provide a minimum of 30 non-umbilical downhole deployment valves (NU-DDV) that will be deployed in Eni’s critical wells. The goal, Weatherford says, is to improve the operational safety of those wells, as well as reservoir performance.
“This award is the result of two years of R&D collaboration with Eni to launch a downhole casing isolation valve with RFID (Radio Frequency Identification Device),” said Dean Bell, President, Drilling, Evaluation and Intervention for Weatherford. “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 unwanted formation influx while tripping.”
Weatherford says that during MPD or UBD applications, the NU-DDV addresses operators’ need to improve process safety by mechanically isolating the surface from the reservoir during tripping, thereby eliminating the need to kill the well. The RFID-enabled valve is said to eliminate external control line and clamping operations, thus providing increased system reliability, decreased installation time and removal of personnel from the red zone.
