New methodology finds shear information in P-wave data. It seems that every once in a while a new idea comes along that makes people slap themselves in the fore-head saying, "We've been doing this wrong for HOW long?" When it comes to multicomponent seismic, a new company named VertiShear might just set the forehead-slapping into motion. Let's look at standard multicomponent seismic acquisition. To acquire the true full elastic wavefield, contractors have been combining three-component geophones with three sources at every source station. This creates a true nine-component dataset. And it's ridiculously expensive. But it's still considered the only way to get a true full elastic wavefield dataset.
