Resistance Array Tool (RAT)

The Resistance Array Tool has 12 micro resistance sensors deployed on bowsprings to determine the water hold-up profile across the whole well-bore.

Water (brine) is conductive, while oil and gas are non-conductive.
  • Cross-sectional water hold-up profiling.
  • 3D imaging of water hold-up profile with MAPview software.
  • Water hold-up in any fluid regime in vertical to horizontal wells.
  • Memory and surface read out operations.
  • Simultaneous operation with other Sondex UltrawireTM tools.
  • Combinable with other tools of the Multiple Array Product Suite via Rotational Alignment Subs (RAS).
