DESCRIPTION OF THE EQUIPMENT

1. The Well Analyzer

The Well Analyzer is a computerized instrument for acquiring acoustic liquid level data, acoustic pressure transient data, dynamometer data and motor power/current data in one compact package.  The Well Analyzer consists of a notebook computer and electronics package housed in a rugged case.  The computer controls data acquisition, processes and analyzes the data, and displays the results. Superior state-of-the-art sigma-delta technology digitizes the signals from the various transducers

2. Remote Fire Gas Gun (WG)

The remotely fired gas gun (WG) generates an acoustic pulse and detects the downhole reflections. The gas gun includes a volume chamber which is filled with compressed gas to deliver the acoustic pulse to the well. A microphone housed in the gas gun detects the shot, collar and other wellbore reflections, and liquid level. The serial number of this type of gun consists of the letters WG (on newer units) followed by three digits. For example: WG123.

The standard unit is manufactured entirely with 316 stainless steel and has a working pressure of 1500 PSI, but the design can be modified to operate up to 3000 PSI. A remote fired gun assembly (brand new and never used in the field) has been successfully pressure tested with water to a maximum pressure of 7500 psi. Contact Echometer Co. for further details.

Attaching the Remote Fired Gas Gun to the Well

The following figure shows the recommended installation of the gun onto the wellhead, assuming the acoustic measurement will be undertaken through the casing valve.
