This artificial lifting equipment, as we mentioned before, has a gun that generates a pressure that travels to the annular casing and is reflected by the collars and the fluid level. The reflected pressure waves impact the microphone (a fundamental part of the equipment), generating the electrical signal. The electrical signal is fed by the well analyzer, which automatically processes the signal or is directed to the amplifier recorder that filters the signals and prints them on a paper roll.
There are two important factors that you must take into account when selecting a type of gas gun:
The first factor is that the gun must generate a shot that results in the collars being these counted to the deepest of the well and the second is that the gun must generate a shot with enough force and power to generate the reflection in the pressure waves coming from fluid levels and thus be able to be distinguished.
The pressure of the waves reflected from the fluid levels is greater than the volume or greater than the pressure discharged from the annular casing.
And you may wonder, but why should I acquire the gas guns? And although there are many reasons, the main one and the one that should interest you is that with it you can optimize your oil wells.
Thanks to its integrated system for the acquisition of data together with instruments for acoustic measurements and fluid levels, they make it indispensable equipment when it comes to increasing reservoir performance.
Here are the Echometer Gas Guns so that you know the important function of each and him because they should not be missing when making a diagnosis of a gas or oil well:
Compact Gas Gun
This equipment offers superior performance by having a double-disc microphone with sound cancellation as it consists of a 10 cubic inch volume chamber with a quick-opening gas valve. The chamber is generally filled with carbon dioxide or nitrogen gas at a pressure in excess of the well pressure.
When the valve is opened, a pressure pulse is generated that travels through the gas well where the chamber can be charged when necessary to obtain the desired record.
While the gas pressure is sufficient, it can be released from the well into the volume chamber to create a pressure pulse (implosion mode) and an external gas source is not necessary for this situation.
One of the reasons for acquiring this equipment is that the operation of the compact gas gun in implosion mode allows debris to be discarded from the well to be discharged into the gas gun volume chamber, which results in greater maintenance requirements.
Automatic Gas Gun
The Echometer automatic gas gun uses a high-performance microphone with an excellent signal-to-noise ratio, along with a 12 cubic inch volume chamber.
A solenoid valve releases gas from the gas gun volume chamber into the well where the solenoid is automatically operated from the well analyzer system or from the M. Eye model, it cannot be operated in implosion mode.
The automatic gas gun is required for automatic acquisition of compromising pressure data, this being an important reason to have it. It is usually supplied with a 1500 PSI pressure gauge and a 1500 PSI pressure transducer.
Wireless Gas Gun
This gun uses a high-performance microphone with excellent signal reception, along with a 12 cubic inch volume camera.
Like the automatic gas gun, a solenoid valve releases gas from the gas gun volume chamber into the well where the solenoid is automatically operated from the wireless system. The Fire Gas Gun command cannot be operated in implosion mode.
5000 PSI Gas Gun (Automatic and Wireless): Operates manually and is ideal for use with a gas lift or high-pressure wells. It is normally used in implosion mode but can operate in explosion mode.
15000 PSI Gas Gun: This gun is used to determine fluid levels, well pressure and to locate corrosion inhibitors. In implosion mode, the volume chamber in the gun is released at a lower pressure than the well, then the valve opens quickly to release the gas from the well to the gas gun to generate the shot.
The 15000 PSI Echometer gas gun performs better using pressure between 1500 and 15000 PSI. However, very good results can be obtained when used with a pressure higher than 1500 PSI (100 ATM) by means of a 1/8 ”orifice valve, which is a standard measure for most high-pressure wells, a fact that makes you have it at the time of performing the analysis of the wells.
It is well known that artificial lifting allows wells that you thought to be deficient to come back to life, becoming productive again; and at UPC Global we are experts in making that happen. Optimizing them is our mission and with the necessary equipment (such as Gas Guns) we know it will be possible.
