Description - 4+

In petroleum exploration and development, formation evaluation is used to determine the ability of a borehole to produce petroleum. Essentially, it is the process of "recognising a commercial well when you drill one".

This app includes the following calculation

 Basic Core Analysis
        Porosity
        Oil Saturation

 Well Logging
        Archies Equation - unknown porosity
            Water Saturation
            Formation Resistivity Factor
            Resistivity Index
            Flushed Zone Saturation
            Ratio of water saturations
        Archies Equation - w/known Porosity
        Mud Relationships
            Mudcake resistivity
            Mud filtrate resistivity
        Fluid Resistivity at Temperature

        Temperature vs Depth
            Temperature at depth
            Geothermal Gradient
        Formation Resistivity (Correlations)
            Sandstone Formations
            Carbonate Formations
            Low Porosity Carbonate Formations
        Spontaneous Potential
        Porosity
            Density Log
            Sonic Log


Great reference for Engineering students and Practice Engineers.
