I think all is good advice. Best is having a well versed attorney.
The in perpetuity clauses might be a concern if you have thoughts of sale/transfer of the property in the next few years.
I am not an attorney and this is not the place to get or give legal advice but O&G leases are pretty standard.
As the owner (lessor) you give a development company (lessee) the exclusive right to develop and market
your minerals in exchange for a share of the proceeds from the extraction and sale. The development company gets the lion's share (80%or more) and you get the scraps.
Once a company leases the rights to develop they have a fixed window in time to begin operations. In PA that is typically 5 years and most leases contain an option to extend that window for another 5 years. They will pay uou an upfront and substantial "bonus" just for signing with them and the same bonus if the need to renew.
If they do not act to begin production - e.g. start permitting and/or drilling in that initisl time window the lease is null and void, you keep the bonus, and you can re-lease with the same or another company on new and udually better terms. I have one interest that has been renewed and re-leased multiple times for almost 500K in bonus money and not a drop of oil or cubic foot of gas has been extracted. The current lessee (EQT) just exercised their option to etend last year and if they do not begin production by Dec 2026 it will lapse again. Almost money for nothing but there are no chcks for free.
Once production begins the lease becomes "
held by production" and as long as the company continues to produce any amount of O&G and pay you dividends on the sale it remains in effect. It does not expire and you cannot cancel it without agreement from the lessee. I have one lease that was executed by my great grandfather in 1899. It paid $100 per year and is still current because the current lease holder (EQT) continues to operate one dinky little gas well that does not pay for itself. They do that just to retain their rights to future development. The good news is they only have vertical rights so they cannot unitize the propert for the horizontal drilling and fracking needed for Marcellus development and have to renegotiate if they decide to go that route. As a result some contentious correspondence has been exchanged. Meanwhile my rights as the current minersl owner are locked up by that decrepit old farmland well.. So be very careful about what rights you sign away. Get a lawyer experienced in mineral rights to advise you - the companies have an army of them and they are not your friends.
A mineral lease is an encumbrance on the property. You can sell the surface rights to the property and retain the mineral rights. The opposite is also true. I own (inherited) mineral rights to the old family farms but no surface rights.
If you own surface rights but not mineral rights you will be paid for any surface activities or access needed to extract someone else's minerals. That would be a separate surface access lease.
O&G companies will wave tens or even hundreds of thousands of dollars under your nose. When they do that they are looking to make millions in exchange and will take advantage of you given the slightest chance. I get letters and phone calls almost weekly from third parties trying to
BUY my mineral interests that are already under lease. They all start the same way - they want to "help me out" with immediate cash....
If you are an O&G mineral rights owner get educated, get an experienced O&G lawyer, and get protected. The jackles are everywhere, they do not have your interests at heart, the leases and laws are complex, and they will take every advantage of you they can.
