Paper Number: SPE-188415-MS
.... The most popular of these methods is mud-pulse telemetry ( Gearhardt et al, 1981 ). This can be either a positive pulse (increase in pressure), a negative pulse (reduction in pressure), or a continuous wave (sine wave) signature ( Hutin et al, 2001 ). All pulses travel from the MWD tool through...
