What Are PUDs (Proved Undeveloped Reserves)?
An educational overview of PUDs — what makes them “proved,” how they’re discovered, and why investors view them as high-potential assets.
“PUDs” stands for Proved Undeveloped Reserves. That’s a technical way of saying oil and gas that’s known to exist but hasn’t been drilled yet.
Think of It Like Real Estate
Imagine you own land with a fully surveyed building plan — you know exactly what you could build and how much it would cost, but construction hasn’t started. That’s a PUD. The resources are proven by geological data, but you still have to drill to reach them.
Why Investors Like PUDs
- They combine lower risk (because the reserves are proven) with higher potential returns than producing wells.
- They often come with clear geological data, nearby well comparisons, and production forecasts.
The Catch
PUDs still require upfront capital for drilling, and there’s always operational risk. But compared to unproven “wildcat” wells, PUDs are considered a safer bet with significant upside.
In short, they represent the sweet spot between known reserves and future opportunity.
