Multiple Array Production Suite - Resistance Array Tool (RAT)

The Sondex Resistance Array (RAT001) Tool has 12 micro resistance sensors deployed on bow springs to determine the water holdup profile across the whole wellbore. Water (brine) is conductive, while oil and gas are non-conductive. The Resistance Array Tool differentiates between conductive water and hydrocarbons, which are non¬conductive, and will detect very small, fast moving bubbles. Combined with data from the Spinner Array Tool (SAT), Capacitance Array Tool (CAT) and Gas Array Tool (GAT), the tool allows quantitative estimations of volumetric flow rate for each phase with a much higher degree of certainty, and thus provides vital and more precise information for reservoir management.
