About US

Sião Petróleo has founded in Brazil  in 1995. Both companies are privately held limited liability companies. Our headquarters are located in Espirito Santo, Brazil. Together the Sião Petróleo is involved in nearly 16 countries and counting.

Sião has conquered a distinct reputation for having a complete A-Z Heavy Oil Solutions portfolio as well as being a Sand Control and Thermal Insulation specialist. 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.
