This seminar, presented b by 20 Years Geoscience Expert, provides an

Overview

of Production Logging Tools (PLT) and their use in evaluating downhole well performance. PLT involves running specialized tools inside cased wellbores to gather data about fluid flow and well conditions.The presenter stresses that unlike open-hole logging, which focuses on rock properties, PLT measures dynamic conditions. It helps identify where fluids (oil, gas, water) are entering or exiting the wellbore, and at what rates. It can evaluate multi-phase flow.The presentation covered:Conventional PLT Tools: These include spinners (to measure flow velocity), density tools, capacitance tools (to identify fluid types), and gamma-ray/CCL tools (for depth correlation).Multi-array tools (MAPS and FSI): The speaker discusses advanced tools with multiple sensors offering a more comprehensive view of the wellbore.Horizontal well flow: The webinar explores flow in a well at a 90 degrees horizontal inclination, as well as deviations above (92 degrees) and below (88 degrees) that angle.Recirculation: The webinar focuses on the phenomenon of fluid recirculation, with illustrations of the way that the heavier water phase tends to settle in the lower side of a deviated well while the lighter oil phase goes upward at a higher rate.Concepts: The presentation explains concepts, and clarifies that the objective of using PLT is to determine the nature and behaviour of flow. It also explains such terms as accuracy, precision, calibration and flow regimes.The presenter concluded with emphasis that there is no such thing as a perfect horizontal well.AGENDA:What is Conventional PLT?What is Required to Analyze PLT Data?How is the PLT String Transported to the Downhole Target?
