FORTRESS Premium Isolation Valve

FORTRESS isolation valve—testing to a higher standard

 

As the industry leader in isolation valve technology since the first FIV formation isolation valve installation in 1996, we have gone beyond existing standards to understand how and to what extent debris affects valve performance.

We developed 30 different debris mixtures to represent the most common types of downhole debris and varied the mixtures by particle size and fluid density.

Debris types tested

FORTRESS Isolation Valve

The actuation energy required was measured for clean and debris-filled conventional valves; the debris-filled valves required more energy to operate.

FORTRESS Isolation Valve

A remote trigger generates the energy available for operation. Actuating the valve requires a set amount of this energy. Debris consumes even more. Actuation energy plus debris-consumed energy cannot exceed the total available energy.

The actuation energy was then compared for debris-filled conventional valves and debris-filled FORTRESS valves.

FORTRESS Isolation Valve

The actuation force required by the conventional valve increased about 123% because of the debris, whereas that required by the FORTRESS valve increased only about 15%.

FORTRESS Valve Is Debris Tested to Higher Standards

Debris accumulation is one of the biggest factors affecting valve performance. We conducted a study to better understand the effects of debris and how to minimize them.
