Sião also provides end-to-end project management, engineering consultancy, onshore & offshore bespoke components design and manufacturing.
Sião was first in the world to utilize High Precision Lasers to make Sand Control solutions (this gives our Sand Control solutions higher resistance to collapse and greater design opportunities, made in any metal, shape and size).
This and many other engineering achievements have earned Columbia the reputation as an innovative company; aggressive in its passion to achieve outstanding results every time. Sião also has a history of thriving in problem solving or harsh well scenarios.
