OXY

Occidental Petroleum Corporation

A major oil and gas producer headquartered in Houston, Occidental (nicknamed "Oxy") drills for crude and natural gas across the Permian Basin and beyond, and is building large-scale carbon-capture projects through its 1PointFive arm. It was founded in 1920 in Los Angeles, nearly collapsed, then was revived in the 1950s when businessman Armand Hammer struck oil in two wells and took control. Its name comes from the Latin word for "west," and the "Oxy" nickname traces to its 1964 stock ticker symbol.
