However, the Thin Bed Analysis (TBA) is still perceived as overly complicated. The TBA goal is often restricted to the identification of an additional pay in shaly intervals...

Commonly used solutions are limited to shaly sandstone models to account for either presence of graincoating clay in sandstones or laminated shale-sandstone systems. Other solutions rely on volumetric techniques which require subjective interpretation...
