Editing Telemetry (section)

===Oil and gas industry===
Telemetry is used to transmit drilling mechanics and formation evaluation information uphole, in real time, as a well is drilled. These services are known as [[Measurement while drilling]] and [[Logging while drilling]]. Information acquired thousands of feet below ground, while drilling, is sent through the drilling hole to the surface sensors and the demodulation software. The pressure wave (sana) is translated into useful information after DSP and noise filters. This information is used for [[Formation evaluation]], [[Drilling]] Optimization, and [[Geosteering]].
