However, few truly scientific discussions are available on existing methods, let alone the advances necessary for high-data-rate telemetry. Without a strong foundation building on solid acoustic principles, rigorous mathematics, and of course, fast, inexpensive and efficient testing of mechanical designs, low data rates will impose unacceptable quality issues to real-time 606 $aOil well logging, Electric 606 $aOil well drilling 606 $aOrientation$xMeasurement 606 $aWells$xFluid dynamics 606 $aFlow meters 615 0$aOil well logging, Electric. 615 0$aOil well drilling. 615 0$aOrientation$xMeasurement. 615 0$aWells$xFluid dynamics. 615 0$aFlow meters. 676 $a622/.33810287 700 $aChin$b Wilson C$0860858 702 $aChin$b Wilson C. 702 $aHackerott$b Kris 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910806871303321 996 $aMeasurement while drilling (MWD) signal analysis, optimization and design$94023392 997 $aUNINA
