Hamdon Echometer Gas Gun Brochure

The Compact Gas Gun offers superior performance due to its rugged, noise-canceling, dual-disk microphone. The gun consists of a 10 cubic inch volume chamber and quick opening gas valve. The chamber is usually filled with carbon dioxide or nitrogen gas to a pressure in excess of the well pressure. When the valve is opened, a pressure pulse is generated which travels through the wellbore gas. The chamber can be charged as needed to obtain the desired record.

If the well pressure is sufficient, gas can be released from the well into the volume chamber to create a pressure pulse (implosion mode). An external gas source is not needed in this situation.

Senior Tech (now Hamdon Energy Solutions) carries these units in stock and can usually ship within 24 hours.
