La Bomba

The La Bomba Memory Gauge goes the distance when the goal is long term data.

Due to extremely low power consumption, the Reservoir Group La Bomba gauge can run over 2 years on one temperature cycle before battery replacement is required.

Features

  • Provides a long term record of well pressure on a single battery
  • At 1.66” OD and 11.2” long, a robust and durable gauge for various applications
  • Easily adapted with the Reservoir Group Strainer Nipple for use with downhole pumps

Applications

  • Pressure build-up tests
  • Pressure draw-down tests
  • Gradient surveys
  • Production monitoring and artificial lift control
  • Production optimisation
  • Slickline and E-line operations
  • Static, flowing and build-up surveys
