suppose a clean quartz sandstone is completely filled with brine. if the speed of sound in quartz is 16000 ft/sec and the porosity 20%, estimate the speed of sound in the brine filled sandstone. Use rules of thumb for any additional parameters needed.

Solution

Porosity is the quality of being porous, or full of tiny holes. Liquids go right through things that have porosity. Go back far enough and you\'ll find that porosity stems from the Greek word poros for \"pore,\" whichmeans “passage.” So something with porosity lets things through.

porosity 20%

20/40 sand

simple formula

speed=distance/time

speed of sound in brine filled sandstone is 8000ft/sec
