- Lessor and lessee
- The lessor is the owner who grants the lease. The lessee is the company that takes it.
- Bonus
- The one-time payment for signing a lease, usually quoted per net mineral acre.
- Primary term
- The years the company has to drill or produce. If it doesn't, the lease ends on its own.
- Held by production (HBP)
- A lease kept alive past its primary term because a well on the land, or in its unit, is producing.
- Royalty
- Your share of what's produced, free of the cost of drilling. The lease says what else can come out of it.
- Net mineral acres (NMA)
- The tract's acres times your share of the minerals. Half the minerals under 40 acres is 20 NMA.
- Decimal interest
- Your share of a well's production, written as a decimal: net acres over unit acres, times your royalty.
- Division order
- The company's statement of your decimal and where to send your money. Signing one doesn't change your lease.
- Suspense
- Royalty the company is holding instead of paying, usually over a title question or a missing address.
- Pooling and units
- Combining tracts into one unit so a well can drain them all. Each owner shares in production by acreage.
- Pugh clause
- A clause that releases the land (horizontal) or the depths (vertical) outside a producing unit once the primary term ends.
- Shut-in royalty
- A small payment that keeps a lease alive while a gas well can produce but isn't selling.
- Gross proceeds
- Royalty figured on the full price the oil or gas sells for, with no costs taken out.
- Surface damage agreement
- A contract with the surface owner that sets locations, payments, water use and restoration.
- Right-of-way (ROW)
- An easement that lets a company build and run a pipeline or power line across your land. Often priced per rod, which is 16.5 feet.
- Affidavit of heirship
- A sworn statement, signed by people who knew the family, recorded to show who inherited from an owner who died.
