Permanent Installation Gauges

Intervention of wireline or coiled tubing into productive wells has always been considered as a last resort – there are inescapable inherent dangers associated with such operations. On the other hand, the need to gather up-to-date downhole data still exists, as part of a properly managed reservoir-monitoring programme.

Permanent downhole pressure / temperature gauges have been the solution to the above dilemma for more than a decade now – but the risk (and cost) of gauge failures has been high.

Nan Gall Technology Ltd has been manufacturing pressure / temperature gauges for many years and has gained enormous experience during this time. Nan Gall's permanent gauges and surface interface system represent the fruits of this experience.

By working with service providers, Nan Gall tailor their systems to their customers needs.

• Pressure connections are built to specification.
  
• Pressure housings can be sealed by o-rings, metal-to-metal or fully welded seals.
  
• Impedance matching is done exactly to the specifications of the customer's cable specifications.
  
• In-built redundancy can be up to eight-fold (up to eight gauges (or other sensors) on a single cable).
  
• Surface hardware and software to permanently monitor and record all downhole sensors.

In this way, the best available surface and downhole data acquisition systems can be matched with the best cable, clamp and penetrater systems.
