Shortline

A versatile gauge for most wellbore operations

The Reservoir Group Shortline Piezo Memory Gauge is the shortest available in its class and is ideal for applications where longer gauges are difficult to use.

At only 7.83" long and with a 1.25" diameter, the Slimline is compact, robust and ideal for short rig-up wireline and gauge carrier applications. Using a single detachable ‘C’ size Battery Pack, it is capable of recording data for up to a year, helping our clients to perform longer downhole surveys.

Features

  • At only 7.83" long, it is the shortest ‘C’ size battery powered gauge available anywhere
  • Fits into standard downhole carriers
  • Unique electronics assembly is less susceptible to vibration
  • Large 2,000,000 data set memory
  • Long lasting ‘C’ and ‘CC’ size Battery Packs can provide uninterrupted data for up to a year or more
  • Easy to use and can run multiple jobs without re-programming

Applications

  • Gradient surveys
  • Pressure build-up or draw-down tests
  • Production monitoring and artificial lift control
  • Production optimisation
  • Reservoir evaluation, well testing and DST
  • Slickline operations
  • Static, flowing and build-up surveys
  • Temperature logging
  • Multiple well surveys without re-programming
