Echometer Model M: Overview
The device consists of a microprocessor controlled dual channel amplifier/recorder and a gun/microphone wellhead attachment. The gas gun generates an acoustic pulse which travels through the wellbore gas. This pulse reflects from tubing collars and the liquid level. The microphone converts acoustic reflections to an electrical signal. The amplifier/recorder simultaneously processes and filters the signal through two channels and records two traces on a paper strip chart. One channel accents collars, and the other channel accents the liquid level.The operator counts the number of collar reflections to the liquid level and multiplies by the average length of the tubing joints to determine the distance to the liquid level. Acoustic velocity can also be used in cases where counting tubing collars is not available. Labeled timing marks simplify the task of determining time to the liquid level reflection.
