QRS Blue waterwell repair

The QRS (Oblique-Repair-Shell) offers an innovative solution for the repair of wells.

The QRS is a combination of a simple, self-activated and self-repairing system, based on advanced compound technology. The QRS systems are suitable for Water wells, Energy (Cold-Heat) Storage wells and Chemical Disposal wells up to 500m deep. Common problems/applications which can be foreseen;

  • Damaged or torn well filters and risers.

  • External well leaks that cause pollution problems (redox).

  • Damaged and unreliable wells that malfunctions due to sand deliveries.

  • Preventive use by targeted critical pressure tests and service / maintenance activities.

  • Protecting or sealing (critical) connections (glued and screwed).


What are the characteristics?

The QRS is able to repair wells permanent by it’s simple, durable and controlled characteristics. This tool is applicable to tube transitions and filter cracks in wells and will seal the damage or leakage. With the QRS it is possible to repair various wells types through an accurate composed recipe. This recipe offers a swelling and sealing elastomer that is constructed on an inner core of Stainless Steel. The specific applied elastomeric compound is chemical engineered for bonding and activation requirements at low temperature applications (7ºC — 24ºC). This is done by many decades of experience with comparable compound technologies for high pressure and temperature applications in wells.

Why has this been developed?

  • The current range of comparable well repair systems are mechanical complex, expensive and offers a limited application.
  • Most current damages / leaks are not repaired with qualified solutions. The QRS has Lloyd’s certificates.
  • Many wells have become unusable for intended purpose in case of leaks and or damages.
  • Available existing (mechanical) repair systems offer restrictions on capacity, internal diameters and are unreliable.
  • Many wells have to sacrifice efficiency or become unusable when leaking events occur and pollution starts.
  • Within densely built-up environments the replacement or services of Energy Storage wells is costly and not always possible.
