Talk:Gardner's relation

I assume the Vp is P-wave velocity would stand for m/s. I am stocked that the paper was both in metric and old units, what ever it is called. Enlil Ninlil (talk) 07:59, 22 May 2010 (UTC)

I'm afraid that the standard unit for measuring P-wave velocity in a hydrocarbon well is still microseconds per foot (actually of course that's really slowness not velocity). There are a lot of geoscientists in the industry that have trouble coping with metres and metres per second (they're pretty much all american) and an even larger number that have difficulty with feet and feet per second, which can lead to confusion. Metric is slowly winning out, but it's a terribly slow process. Mikenorton (talk) 08:39, 22 May 2010 (UTC)

At least now the common software packages provide an option to convert from one to another. This is especially useful when trying to invert a seismic cube to a meaningful physical property that makes more sense in SI units. Hamsterlopithecus (talk) 21:53, 27 May 2010 (UTC)
