    1. July 28, 2004 Core Laboratories, Pencor Division Geochemical Modeling of Inorganic Scale onsets: Is it useful ? Model Verification and Validation using HPHT and LTHP NIR Technology J. D. Lynn Technical Specialist Advanced Fluid Studies Pencor Division

    2. July 28, 2004 Core Laboratories, Pencor Division Outline Why is scale a problem Inorganic scale Types Causes Prediction Geochemical modeling overview Near Infrared spectrography Case studies

    3. July 28, 2004 Core Laboratories, Pencor Division Problems Imposed by Unexpected Scale Onset Scale is a consequence: Changes in Equilibrium States Temp, Pressure, Volumes Mixing of Incompatible Fluids Injection and influx Drilling, Stimulation, Completion and Workover fluids “Scale” is not vindictive It’s Formation Follows Well Defined Thermodynamic Laws The Laws Don’t Change Understanding the Laws as Applied to the Reservoir is Key
