Companies in this industry manufacture machinery and equipment used in oil and gas exploration and production, as well as water well drilling machinery. Major companies include GE Oil & Gas, National Oilwell Varco, and Schlumberger (all based in the US), along with Shandong Kerui Petroleum Equipment (China), Tesco (Canada), and Weatherford International (Switzerland).
Demand is driven by oil and gas prices. The profitability of individual companies depends on engineering expertise and efficient production. Large companies have economies of scale in purchasing. Small companies can compete effectively by specializing. The US industry is highly concentrated: the top 50 companies account for about 80% of revenue.
