There is a process for this, but it doesn't produce immediate results. Even if we agree with you that the lands are no longer productive, you will have to wait more than a year for them to become available.
First you should acquire a search of the lands/leases to ensure that lands have not been continued within the past year; are not in the primary term; under existing Section 18 notice; within a designated Oil Sands area; there is no productive well on the spacing unit; the rights are not unitized; subject to a gas storage agreement; there is no adjacent producing freehold well for which offset compensation is being paid, or there are no nearby productive wells from which a pool could be mapped on to the agreement. If none of these factors is in evidence, then you can proceed with step two.
Send Continuations a request to review the lands confirming that a search for the above criteria was done. We call this a "third party review". The normal response time is 4 to 6 months. The fact that you are prepared to post the land if it becomes available is not taken into consideration at any time during this process.
Once we have completed the review, we will advise you whether or not we are serving a Section 18 notice. If we are satisfied that the lands are still productive, we will not be able to give you reasons why we are not serving a notice since that could breach the confidentiality of someone else's data. If we do serve a notice, we do not advise the lessee that the notice is a result of a third party review.
The notice is for one year, and it gives the lessee an opportunity to prove that the lands are still productive, so it is possible that the lands will be further continued at the end of the year.
