It is located about 3/4 mile south of where Westheimer Parkway crosses Buffalo Bayou in George Bush Park, about 1/2 mile west of the Barker Cypress intersection and the shooting range.
AFAIK, it is either within GBP or Army Corps of Enginneers property, either of which are public land. The well site is just off the main bayou trail, but shielded by trees and and a single point of entry (good for obvious reasons!).
There are no fences or "keep out" signs of any kind. None of the equipment is operational except for a small pipe rack (sllight odor noted). I would say the biggest danger would be bees that live around some of the tanks and hot or sharp metal surfaces.
Since my children found the site last year while out walking, I have been appreciative of its photographic potential. So far I have shot the area three times, twice by myself and once with Diana.
The site has great potential for everything from studies of the equipment to artistic figure modeling, not to mention model shoots with a "Texas feel":
