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 $a9910790931703321 996 $aMeasurement while drilling (MWD)$92817304 997 $aUNINA LEADER 01591nam0 22003491i 450 001 UON00492189 005 20231205105336.945 010 $a28-405-0043-4 100 $a20190206d1995 |0itac50 ba 101 $afre 102 $aFR 105 $a|||| ||||| 200 1 $aˆL' ‰hostellerie de pensée$eétudes sur l'art littéraire au Moyen Age offertes à Daniel Poirion par ses anciens élèves$ftextes réunis par Michel Zink et Danielle Bohler$gpubliés par Eric Hicks et Manuela Python 210 $aParis$cPresses de l'Université de Paris-Sorbonne$d1995 215 $a505 p., 1 ritr.$d24 cm. 316 $aDono Prof. Alberto Varvaro.$5IT-UONSI F.
