Fluid velocity and direction. The Spinner Array Tool (SAT) features six miniature turbines deployed on bowspring arms, enabling discrete local fluid velocities to be measured at 60 degree intervals around the wellbore.
Phase segregation occurs in many wells, even those with little deviation from vertical. Lighter phases migrate to the high side of the well, heavier phases to the low side. The individual phases flow at different velocities and possibly in different directions.
The Spinner Array Tool (SAT) provides direct measurement of individual phase velocities. Combined with holdup data from the Resistance Array Tool (RAT) and Capacitance Array Tool (CAT), this forms the Multiple Array Production Suite (MAPS), which makes it possible to provide quantitative estimates of the volumetric flow rate of each phase with a much higher degree of certainty and thus provide vital information for reservoir management.
