... to identify zones of interest with good reservoir qualities in addition to hydrocarbon saturation. These mature fields offer a unique challenge in that the petrophysical analysis needs to rely on data from newly drilled cased hole wellbores, necessitating numerous corrections. In this challenging environment...

... Abstract In current market conditions, performing logging operations as efficiently as practically feasible has become crucial to reduce the overall cost of formation evaluation. One of the most important formation evaluation parameters is hydrocarbon saturation. At the same time...

Results from this work show that in an oil-wet reservoir the hydrocarbon saturation plays an important role in the NMR estimated permeability. In addition to the wettability, the NMR estimated...
