Shaly Sand Petrophysics
Clay minerals and shale laminations alter both rock properties and log responses, which can hide productive low-resistivity pay. This course tackles practical formation evaluation in shaly sands, showing how a well-designed core and log programme, combined with rock typing, leads to more reliable estimates of porosity, saturation and producibility.
