Oil and gas wells are probably the most demanding environment for metallic structures. Vast temperature fluctuations, harsh chemicals, high velocity flow rates, and high mechanical loads set their requirements for production. Welltec is a globally operating Danish company that develops and provides well technologies and solutions for the oil and gas industry. The company is dedicated to reducing environmental risks, fuel consumption and carbon footprints by producing safe and lightweight solutions based on clean technology.
Welltec relies heavily on welding in their production stream. One of their newest market entries, the Welltec Annular Barrier (WAB), is a steel construction that allows wells to be segmented for improved production. Their construction calls for multiple welded seams that must all endure the extreme conditions prevalent thousands of meters under the earth’s surface.
