Tracerco Reservoir CharacteriZationGain better insightinto originalfluid saturations.Near Well BoreTracerco Near Well Bore tracer techniques provide ourcustomers with a reliable method of monitoring theprogress and effectiveness during a range of down-holeoperations including::: Coring-Fluid Invasion Measurement:: Hydraulic Fracture and Acid Stimulation In-flowAssessment:: Perforation Positional Flow Measurement4

The Tracerco Core Invasion Measurementtechnique is used to determine the level of drilling fluidinvasion into formation samples. Prior to the start ofdrilling operations through a zone of interest, a specialistoil or water compatible chemical tracer is added tothe mud system providing a constant concentration oftracer throughout the drilling mud system.% InvasionFor Core Invasion Measurement, as drilling progresses,a series of mud samples are taken at specific drillingdepths. Interpretation of the mud sample and core fluidtracer concentration analysis provides::: A tracer/drilling mud concentration ratio atvertical depths:: Extracted core tracer/drilling mud concentrationat specific vertical depths:: Percentage of drilling mud core invasion,calculated from ratio analysisIn addition, contamination of bottom hole samples canbe measured using the same technique.5
