microseism

Quote that explains their finding: "Researchers claim that microseismic activity from long ocean waves impacting the sea bed is what makes our planet vibrate and produces the droning sound. The pressure of the waves on the seafloor generates seismic waves that cause the Earth to oscillate.

2D seismic, then 3D seismic, then microseismic, completion data, well logs, magnetic, gravity, surface linears, etc... It's not surprising that one of the largest customers to the supercomputing industry -- after defense -- is the oil and gas business.

Having people who have never set foot on a drill rig babbling on about 'peak oil' is tantamount to someone who doesn't understand computing betting against Moore's Law. For example: The combination of swell packers for multi-stage fracture stimulation of multi-lateral wells in tight oil and shale gas resource plays, coupled with multi-azimuth 3D seismic for detecting naturally occurring fracture networks,and microseismic for frac job design has completely revolutionized the US hydrocarbons business in the past few years. These are new technologies applied to produce oil and gas resources that used to be considered uneconomic.
