Great work! What is also fun is to grab the movie pointer and drag it back and forth quickly, you'll especially notice the 2000+ years as the drilling of the advancing water front! East meets West

One thing that is apparent when one does that is the asymmetry of the development. There is clearly a progression predominantly from the west, which I believe is due to the tar mat present on the east side that hinders the flow of injected water. Also, note that the west injectors are drilled uniformly along the original oil water contact (OOWC), in contrast to those one the east, and they were put in earlier.
