Spinner surveys as valuable tools for gathering critical data on fluid flow rates and flow profiles. These surveys involve the deployment of spinner tools along the wellbore. As fluid flows through the well, the spinner detects its velocity and direction, providing insights into the behavior and characteristics of the well and/or formation under investigation. The resulting flow profile can help assess the efficiency of production or injection operations, identify potential flow restrictions, evaluate well performance, and/or optimize reservoir management strategies.

During a spinner survey, the tool is deployed using wireline to measure fluid velocities at multiple depths and at different tool speeds. The collected data is then processed and analyzed to determine flow rates, identify areas of preferential flow, and detect any anomalies or irregularities in fluid movement. Interpreting spinner survey results requires expertise in fluid dynamics and reservoir engineering and is performed by a qualified technical specialist to assist clients identify production/injection zones, evaluate flow distribution, detect crossflow or channeling, and assess wellbore integrity.
