The Basics of Oil and Gas Leases Part II

For those Pennsylvanians located in the Marcellus Shale area, natural gas and oil reserves are now being tapped. Many land owners want to take advantage of the Marcellus Shale development, and are signing mineral exploitation leases to that effect. Most oil and gas leases are made up of similar clauses, and many drilling companies try to maintain a standard lease. This post explains a few of the common clauses you should be on the lookout for, because they may be good or bad for you depending on the wording or your situation.

  • Clauses to begin work:Cessation of Production Clause- specifies what the driller must do to maintain his end of the lease in the event that production ceases.
    • Granting Clause- states that the person signing the lease has the right to grant use of the estate, i.e. is the rightful owner of the estate.
    • Habendum Clause- indicates the extent of the ownership rights that the owner intended to give the lessor. The right to drill, the right to extract, if so how much, how much does the lessor have to pay, etc.
    • Reworking Clause- This benefits the owner of the land, it means that if the driller fails to find oil or gas on the first try, he or she may re-drill to find a production hole. It also means that multiple areas of your land may be drilled on, something some landowners are not amenable to.
    • Delay Clauses (clauses that allow the driller to delay work and still be in compliance with the lease):
      • Unless Clause- states that the lease terminates on a fixed date UNLESS the driller puts in a well or  pays a predetermined rental fee.
      • Or Clause- the driller must drill OR pay rental fees. This is different from the “unless clause” because the driller must then surrender the lease if there is no drilling and no rental paid. There is no set date to end the lease.
      • Savings Clauses (protects the individual leasing the rights, so that they may continue work)
        • Dry Hole Clause- allows the driller to continue drilling or reworking after a dry hole is drilled.
        • Continuous Operations Clause- gives the individual leasing the mineral estate the opportunity to continue working for as long as oil or gas production continues on the land.
          • Some leases allow this and the drilling of additional wells to show continuous operation
          • Some leases allow the driller to complete whatever work on a well has been done in order to see if there can be exercise of the continuous operations clause
  • Pooling Clause- combines small tracts of land and the mineral leases to drill a single well for production. This allows smaller land owners to use oil and gas leases, and also makes the drilling more efficient and (hopefully) easier on the environment. The variations on the pooling clause are:
    • Pugh Clause- modifies the pooling clause so that where possible, a driller must put in a well that would not be pooled with other lands, and therefore that landowner can have more oil or gas produced on his or her lands.
    • Unitization Clause- this clause attempts to combine the use of multiple wells and leases so that an entire field can be worked on without damaging the rights of others (landowners or producers)
    • Entirety Clause- provides apportionment of royalties if the owner of property anticipates a subdivision of the mineral lease (the driller allows others to take over drilling on part of the property) and this protects the owners royalties.
    • Force Majeure Clause- relieves the driller of complying with the terms of the lease if the failure to perform occurs because of some natural disaster, inability to work, or other destructive force. The approved forces are listed in this clause.

These are some of the most common clauses found in oil and gas leases. When looking at your lease, be aware of how subtle shifts in wording can change a clause that normally favors you, into a clause that favors the other party. Leases should be carefully drafted by experienced attorneys and should reflect the desires of both parties. Do not sign a lease without consulting an attorney.
