Is Welding Oxygen the Same as Medical Oxygen?

Welding oxygen and medical oxygen are not the same – they differ in regulatory oversight, handling procedures, and contamination controls. While both types typically exceed 99% purity, medical oxygen undergoes stringent FDA regulation as a prescription drug, while welding oxygen follows industrial standards. In this article, we’ll explore the critical differences between these gases. We’ll …

Why Is Enhanced Oil Recovery Necessary?

Enhanced Oil Recovery (EOR) is necessary because conventional extraction methods typically leave 60-80% of oil trapped within reservoirs. By contrast, EOR techniques can access much of this remaining oil to meet global energy demands. The importance of EOR grows as easily accessible oil reserves continue to deplete worldwide. It’s a critical approach for energy companies …

Where Does Helium Come From?

Helium comes from two main sources: cosmic nucleosynthesis during the Big Bang and radioactive decay of uranium and thorium within the Earth’s crust. However, the helium we use on Earth comes almost entirely from underground deposits formed by radioactive decay—not from the helium produced during the Big Bang.  WestAir supplies helium across California and Arizona. …
