My firm has been conducting a large project in the north panhandle of TX where we are doing specialized inspections on the tank batteries at O&G Well sites.

The smallest size site I've seen is about 1/3 to 1/2 acre. They are bigger if there's crude coming out to which some crude wells will need a pump-jack. Sometimes if there's a pump jack, there will also be some compressors or seperators also which do create some noise.

The volume of productivity of crude from a given well will determine how often you have small tank trucks coming to the site to pump out the holding tanks. Some of these tanks only hold 200-300 barrels of crude or nat. gas condensate. There can be as many as (6) tanks (10 or 12' diameter, up to 20' high) at each well site.

So please consider what kind of traffic might be coming and going. It will be more than just tank trucks. For instance, contractors such as my firm would be coming and going also.
