TIVF Flapper-Seal Tubing Isolation Valve

Overview Library

Save completion time by eliminating multiple intervention runs

The TIVF flapper-seal tubing isolation valve is typically run below the production packer with the production tubing string. It allows automatic filling of the tubing, multiple completion pressure tests before and after setting the packer, annulus fluid circulation, and hydraulic setting of the packer before cycling open to allow fullbore through-tubing access—all without intervention.  The valve is opened using a modified version of the Trip Saver one-time remote-opening mechanism.  

By eliminating six or seven intervention runs, the TIVF valve saves significant completion time, which is especially beneficial in horizontal wells, where intervention with wireline or coiled tubing adds considerable risks and costs.
