Lease

[AngelicaDeAlquezar]

I found this sentence in a document about oil industry:

"Almost all oil production is in the form of crude oil and lease condensates from natural gas production."

Common dictionaries only define "lease" for property renting and hiring, but this doesn't make much sense to me in this context. However, I found this definition for "lease condensates" in some petroleum glossary:

"Liquid hydrocarbons produced with natural gas and separated from the gas at the well or on the lease."

So, my question is how do we understand "lease" here?
Is it the facility, as in "hydrocarbons produced in the refinery facilities"?

All hints will be highly appreciated.
