In short We counted oil and gas companies in Ken's database with headquarters in Colorado on Oct 17, 2026.

• Filter: Companies in Oil and Gas (including oil extraction, natural gas extraction and refining), with headquarters in Colorado, United States, and at least one employee on record.
• Headquarters only. Companies with just an office in Colorado are not counted.
• These are companies in Ken's database (250M people and 24M companies), not every company that exists.
• Some records store the state with a ZIP code, and the state filter misses those, so read the count as a floor. The largest-companies table reads the state from each record's address, so it includes them.
• Counts as of Oct 17, 2026. We check them weekly, and the dates move only when a count or a listed company changes.
• Pages publish only at 50 companies or more. Ken is our product, and these counts come from its company database.
