The Model M is a portable device that uses acoustics to measure the liquid level in a well's casing annulus, featuring a dual-channel amplifier/recorder and a gun/microphone wellhead attachment.
The Model M is a portable device that uses acoustics to measure the liquid level in a well's casing annulus, featuring a dual-channel amplifier/recorder and a gun/microphone wellhead attachment.
The gas gun generates an acoustic pulse that travels through the wellbore gas and reflects off tubing collars and the liquid level. The microphone converts these reflections into electrical signals, which the amplifier/recorder processes through two channels and records on a paper strip chart. One channel highlights the collars, and the other highlights the liquid level. The distance to the liquid level is determined by counting the collar reflections and multiplying by the average length of the tubing joints. Acoustic velocity can also be used for this measurement, and labeled timing marks help determine the time to the liquid level reflection.
