Valued at a market cap of $41.2 billion, Houston, Texas-based Occidental Petroleum Corporation (OXY) is an integrated oil and gas company with operations in the U.S. and internationally. It operates through three segments: Oil and Gas; Chemical; and Midstream and Marketing.
Companies valued at $10 billion or more are generally considered "large-cap" stocks, and Occidental Petroleum fits this criterion perfectly. The company also produces a wide range of basic and specialty chemicals and provides midstream services, including transportation and marketing of energy products.
