# Survey
{% hint style="info" %}
Much like actual oil fields, your Oil Fields NFT comes with finite reserves.
{% endhint %}
Interested in taking your oil reserves to the next level? For a small fee, you can go on a wild oil field exploration and hunt for those elusive Yield Boosters, which are known to boost reserves and oil output like magic.
There are three levels of survey available to players: basic, intermediate, and deep.
Basic survey only searches the shallow underground, while deep survey delves deep and has a higher chance of uncovering more potent Yield Boosters. Choose the level that best fits your needs and goals, and start boosting those oil reserves!
