Oklahoma Drilling without a Lease

I have seen other discussions on this topic but no clear answer.

In Carter County, Ok, Continental has received approval from the Corporation Commission to drill multiple multiunit horizontal wells. Just guessing but probably 20 or so in various sections including, Section 1, 2, 11, 12, 35 and 36. Some of these are not currently leased to Continental. I have not received any notice regarding forced pooling, so just wondering how they could start drilling before a lease is signed.
