Can we submit an archaeological report for the lease block that was prepared for a previous lessee under a different OCS number?

We suggest that these previously submitted archaeological surveys be resubmitted well in advance of any plans for exploration or development for the block.

In most cases, MMS does not accept in-filling of lines over a previously shot 150-meter grid. We operate a lease that dates back before any archaeological surveys were required and have never conducted any surveys on the lease. If we continue to develop our lease now, do
