Understanding PUD vs. Non-PUD Opportunities
A quick guide that explains how proven and unproven reserves are classified, helping investors understand where risk and reward meet in oil projects.
If you’ve heard the term PUD (Proved Undeveloped Reserves), it might sound like complicated industry language — but it’s actually a simple way to describe risk levels in oil projects.
What Is a PUD?
A PUD is a location where oil or gas has been proven to exist, but the well hasn’t been drilled yet. Data from nearby wells or seismic studies confirms that hydrocarbons are there.
What Is a Non-PUD?
A Non-PUD is an unproven area — meaning there’s no direct evidence of oil yet. These are the true exploration plays and carry more risk.
Why It Matters to Investors
- PUD projects: Lower risk, steady returns, and easier to forecast.
- Non-PUD projects: Higher risk, higher potential reward, but less certainty.
Many experienced investors build balanced portfolios — combining the stability of PUDs with the upside potential of new exploratory wells.
