Thus far we’ve described the functional characteristics of an oil Well. These are the Facilities. What most people see, though, are not those, but the assembly of pipes, valves, and pumps that implement the Well. Figure 21-7 shows our example with clusters of hardware specifically labeled as Well Assemblies. Each Well Assembly is the piping with a single diameter (and other equipment) that implements a section of the Well (between intersections). In the example, four Well Assemblies are shown:
· The Well Assembly “45” is the outer pipe that runs from the Kelly Bushing almost to the bottom of the well, ending at 2300 feet.
· The Well Assembly “46” is a smaller piece of pipe (perforated, so fluids can enter) overlapping ...
