Systems

Fluids moving in the well system have thermal mass and can heat or cool the areas they touch.

These temperature changes carry valuable information about fluid behavior, especially flow rates and profiles.
The trouble is, the physical laws of thermodynamics and fluid dynamics are incredibly complex, and the interactions between them even more so. The 3D world of metal, concrete and earth we call the well system adds more complexity. Extracting accurate flow data from this environment may seem like an impossible task.

But not for Cascade.

Twenty years ago, TGT founded its business on transforming temperature changes into flow information, and since then we have taken this capability further than anyone. Today, Cascade delivers that capability through our ‘True Flow’ products to reveal flow like never before.
