Rockman,
Thanks for pointing me toward the role of the well site geologist.
I think that the limited scope of what I am doing still is not clear. I am not writing a book about oil drilling. I am writing a novel about the psychological, political, and economic forces that will determine the next generation's life outcomes. The section on oil infrastructure is only a couple of paragraphs long.
Here is a rough draft of this section. The "program" is a TV program that the narrator is describing to the reader.

Then the program examined the concept of peak oil. During the 20th and 21st centuries, we humans have been sucking oil out of the ground at fantastic rates. To convey the scale of this undertaking, the program focused on the amount of activity that's required to produce oil in just one country, Kuwait.
This small country produces 2.8 million barrels of oil a day, which is 3.2% of the world's daily output. Kuwait has approximately 1100 oil wells. The site for each well had to be selected through geological analysis. Each well then had to be drilled separately and fitted with a wellhead. This process alone required the involvement of a small army of specialists: casting companies, wire line companies, coil tubing companies, filtration companies, directional drillers, tong companies, mud engineers, completion specialist, well testers, drivers, cementers, and well site geologists.
Because Kuwait's oil fields are ageing, many wells require water to be injected into them in order to force oil up to the surface. So many wellheads required the installation of pipes for bringing this water from some source. Once the water has been used, it creates more problems because it has to be pumped to disposal sites and cleaned of residues.
As petroleum is brought to the surface, it is usually accompanied by natural gas. One might expect this by-product to be considered a plus. But often it is just an added burden because it is expensive to convey to ports and consumers. So it is often just flared off, adding to petroleum's overall environmental damage. The flaring process has to be carefully supervised. Flowlines had to be installed for conveying oil from each wellhead to gathering centers, where it is combined with oil from other wellheads in the field. From these gathering centers, oil must be pumped to storage tanks, refineries, and shipping ports.

If you can add any key items to this brief summary, I would be most appreciative. The list of items in my previous post are things that I though I might explain briefly for the reader.
