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.

Features:

• 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).
