When is an Oil, Gas and Mineral Lease Considered Expired?

Linda:

I believe the wording in the original lease needs to be reviewed but most likely the operator has the necessary action to hold the lease if all has been completed except the fracking of the well.

Same situation in LaSalle County except well is drilled but no frac yet/3 yr lease will expire in Dec 2012. Do they have to complete well before end of lease
