Successful Application of the Key Well Concept to Enhance Formation Evaluation

An integrated system of acquiring data from key wells to calibrate petrophysical models has proven effective in formation evaluation programs. In the key wells, extensive logging, coring and fluid sampling programs provide the data used to develop better predictive models for water saturation, lithology, porosity, and permeability. These enhanced models have reduced uncertainties and resulted in more accurate hydrocarbon-in-place calculations.
