Calibration of water saturation models derived from traditional wireline data in tight shaly gas sandstones, Part 1: Modelling

Reducing predictive uncertainty in log-derived water saturation models in a giant tight shaly sandstones – A case study from Mesaverde tight gas reservoir

“…The calibration coefficient is introduced by using "Finding true position" technique based on porosityeresistivity cross plot (Amiri et al, 2012b) to improve prediction of water saturation by conventional models in tight shaly sandstones.…”
