"Outer boundary line" means the exterior limits of the land included within the lease or unit comprising several contiguous parcels of land in one or different ownerships which are operated as a single petroleum lease or operating unit. In determining the continuity of any such parcels of land, no public right-of-way lying within the lease or unit shall be deemed to interrupt such contiguity.
