A pretty complicated sentence structure

Excepting there from :..(all kinds of rights to hydrocarbon substances)..,water, claims or rights to water, together with appurtenant rights thereto, without, however, the rights to enter said land nor any portion of the subsurface lying above a depth of 500 feet, as expected or reserved by Deed of Official Records."

Does it mean that the person (for whom this is the restriction to his/er land rights) is forbidden to enter the property nor the any surface that is HIGHER than 500 feet? Sentence structure seems complicated and that "subsurface ABOVE 500 feet" there is even more so.

This is indeed ,someone's deed, and I'm looking at it, there's also a part that says that the units of 201 to (a certain number) INCLUSIVE that are not within that person's rights and yet another that says UNION 201 is part of the person's property, which is part of the condominium, all's very confusing right here.
