Fiber Optic Technologies

Fiber optic technology allows operators to reliably measure temperatures across an entire wellbore.

When it comes to fiber optics, getting them into the ground is the challenge. SageRider has a very high success rate deploying fiber opticswhich is why the majority of our customers use us for multiple installations.
