I guess my other post got deleted. What is the definition of Perforation as used here? Is it where the holes are?

I am just saying why should there be a question of the NMA? It has not changed since Anadarko drilled on it. It has been on the court records for years that way. Why would it change now? I am not understanding.

I do not see the section, township and range here, but sometimes a river can change your acreage. I think this last post went with another topic line. Your decimal will be different for a vertical versus a horizontal well due to the spacing difference.
