Electric Circulation Valve
An electrically controlled circulation valve.
Advantages
- circulation-window area matches the inner diameter of 89 tubing;
- corrosion-resistant Cr13 execution;
- abrasion-resistant closure allows fracturing;
- built-in telemetry system (pressure and temperature measurement inside and outside the tubing);
- has a channel for routing the control line to the equipment below.
Specifications
- differential pressure rating: up to 100 MPa
- temperature: up to 120/140 °C
- setting depth: up to 5000 m
- size range: 89/178
Application area and experience
The valve is designed to connect the tubing and annulus spaces to allow displacement of drilling mud in the annulus after fracturing. It can be used in multilateral wells to control inflow from lateral bores. The valve is controlled and its parameters are monitored from a surface station with remote-connection capability.
