An oil and gas lease runs in two terms. The primary term is a fixed window, usually three to five years, when the operator must drill or the lease ends. A secondary term then keeps the lease alive for as long as the well produces in paying quantities, which can stretch for decades.
That second phrase is where Texas landowners quietly lose control of their minerals. A lease you signed for five years can bind your land for forty, on the strength of one marginal well.
Before founding this firm, Attorney Daughtrey spent nearly a decade inside oil companies as a licensed attorney and landman. Holding acreage cheaply was part of that job. Here is how the two terms actually work, and how operators use the second one to keep land they are barely using.

What is the primary term in an oil and gas lease?
The primary term is the trial period. An operator gets a set number of years to begin drilling or production. Do nothing in that window, and the lease usually ends on its own.
Most Texas primary terms run three to five years. The part of the lease that sets this is the habendum clause, the language that controls how long the lease lasts. A shorter primary term returns your land to you faster when the operator never drills.
Here is what the length really decides. A five-year term lets an operator sit on your minerals, with no duty to act, for five full years. During that time you cannot lease to a company that would actually drill.
Why does the length of the primary term matter?
Operators prefer longer primary terms because they can hold your acreage while deciding whether it fits their plans. The timing of a lease offer is rarely random. Usually it means a well is already being planned nearby.
A shorter term pressures the operator to move or release. Whatever you fail to negotiate here stays in the lease for its entire life. That is the first place a landowner gives away leverage without knowing it.

What is the secondary term, and how long can it last?
If the operator drills and finds oil or gas, the lease rolls into the secondary term. This phase lasts for as long as the well keeps producing, which can mean decades.
There is no fixed end date. The lease survives on the condition of production, not on a calendar. That is why a short lease can control your land for a generation.
What does “production in paying quantities” mean?
This is the phrase that decides everything in the secondary term. Texas courts, going back to the Supreme Court’s decision in Clifton v. Koontz, measure it by whether a well earns more than it costs to operate.
The difficulty is the margin. A well limping along on a few barrels a month may or may not meet the standard, and the operator holds the production data. Operators report output to the Railroad Commission of Texas, yet reconciling those figures against the paying-quantities standard is rarely straightforward. Whether your lease is still valid can turn on numbers you never see.
How do operators keep a lease alive with almost no production?
This is the part landowners rarely see coming. An operator can hold hundreds of acres with a single marginal well, producing just enough to argue the lease survives.
The industry calls this being “held by production.” The operator does the bare minimum to keep the acreage, not to develop it. Your unused mineral rights sit locked under a lease you cannot exit and cannot lease to anyone else.
From inside an oil company, holding acreage cheaply is a recognized strategy, not an accident. A landman is measured on securing and keeping leases at the lowest cost, not on paying a landowner fairly. The standard lease form is built to make holding easy and releasing hard.
What keeps an operator from trapping acreage they are not using?
The difference between a lease that frees your unused land and one that traps it comes down to language the standard form leaves out. A Pugh clause or retained-acreage provision can release the parts of your property the operator never develops.
Knowing which language does that, and getting an operator to accept it before you sign, is the real work. Once the lease is signed without it, that leverage is gone for the life of the lease. Our guide on Texas retained acreage clauses shows how much unused land these provisions can free.
What does this look like from the landowner’s side?
Most writing about lease terms is aimed at the industry or reads like a dictionary. The landowner stands somewhere very different: signing a document the other side drafted, wrote, and understands far better.
Their landman negotiates leases for a living. You may sign one or two in a lifetime. That gap is the whole reason the secondary term surprises families years later. Lease values also move with the market, which the Texas Real Estate Research Center at Texas A&M tracks across the state.
This is the kind of lease we review before it is signed, and the kind we examine when a landowner suspects a played-out well is holding their minerals hostage. Our oil and gas lease negotiation work, and our broader Texas oil and gas lease guide, come at it from the operator’s side of the table.
Frequently Asked Questions
How long is the primary term in a Texas oil and gas lease?
Most Texas primary terms run three to five years. The shorter the term, the sooner your land returns to you if the operator never drills. That length is negotiable, and it is set in the habendum clause.
Can an oil and gas lease last forever?
Effectively, yes. Once a lease reaches the secondary term, it survives for as long as the well produces in paying quantities. A single low-output well can hold your minerals for decades unless the lease was written to prevent it.
Can a landowner end a lease that is held by production?
Sometimes. If a well no longer produces in paying quantities, the lease may have already ended, even if the operator still treats it as active. Proving that turns on production records and Texas case law, which is where a landowner usually needs help.

Before you sign, know which term controls your land
The primary term decides how long an operator can sit on your minerals. The secondary term decides how long they can keep them. Both are set by language most landowners never negotiate.
If an operator has sent you a lease, or you think a marginal well is holding land you could lease to someone else, that is worth a look before you act.
