Welcome to the forum!
Every question is important! If you read the existing lease, it will have the time frame listed in it. If the well is drilled in the first time frame (called the primary term) and it is productive, then the option to renew is not needed. The productive time frame is called the secondary term. Most leases have a clause similar to “It is agreed that this lease shall remain in force for a term of __________ years from date (herein call primary term) and as long thereafter as oil or gas. or either of them, is produced from said land by the lessee.” If that well ceases to produce but another is drilled within the designated time frame (usually 90-180 days), then the lease will continue. Our family has leases that are 100 years old.
If no well is drilled in the first time frame, then the operator has the option, but not the obligation to extend the lease for the option time frame (often two years). If a well is drilled and is productive within that time frame, then the lease continues under its terms.
