Fracture Aperture Computation Using Dip Data | FMI/FMS Image Log Tutorial in TECHLOG

This video explains how to compute fracture aperture using dip data based on the method introduced by Luthi and Souhaite. In water-based mud systems, fractures appear as conductive features on electrical image logs such as FMI and FMS. Their aperture can be estimated by analyzing the excess current generated by the fracture anomaly relative to the formation background. The calculation uses an equation linking fracture width to flushed zone resistivity (Rxo), mud resistivity (Rm), and tool-specific numerical constants c and b. This method provides a reliable and practical way to quantify fracture aperture directly from image log data, supporting structural interpretation and reservoir evaluation. #FractureAperture #ImageLogAnalysis #FMI #FMS #DipData #GeologyTutorial #Petrophysics #WellLogging #FractureAnalysis #BoreholeImaging #ReservoirCharacterization #GeoscienceEducation #OilAndGasTraining #LuthiMethod #FormationEvaluation #GeotechnicalEngineering #ElectricalImagingTools #WBM #FractureWidthCalculation #PetrotechnicalSkills#techlog
