Deep Gas Well De-liquefying
3,500 - 8,000 Feet (1,066 - 2,438 meters)

This variant of the standard Airwell Oil & Gas technology is currently undergoing field testing and is hoped to soon be commercially available. It is expected that this product will allow Airwell pumps to recover liquid from zero to 200 barrels of fluid per day from depths in excess of 8,000 feet (2,438 meters).
This equipment will combine many of the long established Airwell concepts and features while including some additional features specific to these deep and sometimes horizontal gas wells.

Horizontal or Vertical operation

This deep gas well system will work to the same efficiency if the pump is mounted vertically or horizontally with no effect on the performance, efficiency or reliability of the system.

Low flow

Even though Airwell Pumping Systems are capable of higher flows, they have traditionally received most acclaim for their ability to pump wells with very low flow rates. An Airwell Pumping System will optimize the well production by automatically adjusting its flow to match the production of the well, even down to zero flow rates. There is no risk of costly pumping downtime from damaged pumping equipment in low flow situations.

No Gas locking

Due to the nature of the Airwell Pump it is impossible for the unit to gas lock when the intake is set below the lowest perforation.

Silt Handling

One of the main features exhibited by the entire range of Airwell pumps for the last 25 years has been their ability to pump silts and other fines and particulates suspended in the fluid, without any effect on the performance and reliability of the pumping unit.

No restriction on the gas supply

When utilising any Airwell system the production gas is produced up the casing or “back side” and therefore the up hole friction of the gas is reduced as much as possible. The gas production from the well can be maintained constantly as there is no need to periodically shut in the well as there might be for Plunger Lift systems etc.
If there is sufficient rat hole available in a well, it is possible to have the production perforations completely de-liquefied and therefore relieving the well of as much back pressure as possible to optimise gas production.
This system will operate independent of bottom hole pressure.

Centralised Power Supply Requirements for Multiple Pump Sites

With an Airwell Pumping System it is only necessary to have a power source available at one central location. From this point the energy (compressed gas) is directed to the various wells using a high pressure gas pipe or hose. A well location could be up to 2 miles (3.2 kilometres) from the power source. This means that every pump has a 24/7 power supply without the costly expense of distributing mains power.
This use of Airwell technology to de-liquefy gas well were depths are 8,000 feet (2,438m) will typically be combined or associated with a well head gas compression system. In this way the well head compressor will be performing two functions, one to reduce well head casing pressure and two to drive the gas well de-liquefying system.

High "Down Well" Reliability

An Airwell Pumping System has minimal moving parts and only quality materials have been used in their manufacture. This makes the patented Airwell Oil & Gas pumps very reliable and reduces the pumping down time experienced by other systems in the event of equipment breakdown. Much of the maintenance process is completed at surface level. This means that maintenance can be done efficiently and with less interference to the well's productivity.

Remote System Monitoring

An Airwell Oil & Gas system can be monitored daily from any of their offices. Airwell Oil & Gas staff are able to monitor and provide clients with regular information on the performance of their Airwell System:
All of this information can be emailed to a client in a daily or weekly report.

Low Environmental Impact

The use of multiple Airwell pumps from one centrally located air compressor eliminates the need to supply power to each well, as is currently required for existing pump jacks. In addition, an Airwell Pumping System is quieter and less visually intrusive as it is compact and has no moving parts at the head of the well.
