Are you oilfield trash? Can you find your way around the Gulf of Mexico? Did you ever have to stop at the nearest rig to see where you were? If you have, then you might understand how to figure this one out.

To solve the puzzle you will need to plot the reference points given, then find the specific three-digit numbers associated with each point. This may require special skill or research. The hints may help.

The cache can be found at N 29.AB° by W 090.CD° (There will be six digits after the decimal.)
