Quantum Downhole Systems has licensed two unique technologies to create Q-Vak, a revolutionary new cleanout technology. Q-Vak combines Dual Coiled tubing umbilical design and Source Rock Energy's specifically engineered jet pump to remove solids and liquids from well bores. The primary function of this technology is to create a low pressure environment in the well bore to pump the fluid and/or solids to surface. This technology helps E&P companies to better exploit the reserves in their properties.
Due to the low pressure of our reservoirs, frac sand cleanouts are a common technique used during the completion process in the WCSB. One of the unique features the Q-Vak offers is the ability to jet through a high pressure nozzle on the bottom of the pump to break through or liquefy sand. The pumping process can then be restarted and the solids removed from the well.

Brief description of pumping mode
How it Works
The equipment utilized on location to deploy and operate Q-Vak uses 75% less fuel than a conventional cleanout operation, providing both economical and environmental benefit. Furthermore, Q-Vak is directive 033 compliant; UEL and LEL are no longer a concern. Q-Vak utilizes produced or fresh water to run the pump and virtually no gas is vented to the atmosphere.
Cleanout damage is a relatively recent but common problem in our mature basin, many wells have upper zones that can experience short or long term damage using current cleanout techniques. The Q-Vak technology allows E&P companies the ability to economically and effectively clean these wellbores out while not risking temporary or permanent damage to these sensitive zones. Well productivity increases immediately after the Q-Vak has been run.
When using Q-Vak, the number of cleanouts done on the well will be reduced. Since the well is in an underbalanced state during the cleanout, Q-Vak removes both the well bore fluid and the fluid that has built up near the well bore area. With the Q-Vak process, a higher volume of fluid is recovered out of the well than with conventional cleanout techniques.
