I work in the Oil & Gas sector, and have been involved with subsea well monitoring in the past. Keep in mind that an oil well is a lot more than just a hole and a drill bit - there is a lot of equipment sitting on the seabed[0], and a wellhead and a lot of equipment "topside" too There are a lot of components with a lot of sensors, including vibration (you want high frequency for that), position, flow measurement, pressure, temperature, seismic, sand detectors, water sensors, gas detectors, bearing sensors... Rigs/platforms typically have restricted bandwidth, and it's very expensive to add more. The amount of data generated has always been a problem, and in some projects we've actually logged to disk, and had techs ferry the disks back and forth with them as they rotate in/out.
