Disclosed are a method and system for developing customized bound water transformations to obtain accurate determinations of non-producible water from nuclear magnetic resonance (NMR) logs. The approaches of this invention can be applied for in situ calibration where laboratory NMR measurements may not be possible or practical. In particular, a transformation model directly linking BVI and capillary pressure is developed by calibrating NMR derived BVI with the core data, the novel transformation model utilizes SBVI and/or CBVI models to directly relate NMR derived BVI and capillary pressure responses through the height of the measurement in a borehole. The derived height-based BVI transformation model is applied to the NMR log of the borehole to quantify non- producible water in the NMR log.

L'invention concerne un procédé et un système permettant d'élaborer des transformations adaptées d'eau liée afin d'obtenir des déterminations précises d'eaux non exploitables à partir de diagraphes de résonance magnétique nucléaire (RMN). Les approches de cette invention peuvent être appliquées à l'étalonnage in situ, lorsque des mesures RMN de laboratoire peuvent s'avérer impossibles ou peu commodes à appliquer. En particulier, un modèle de transformation qui combine directement le BVI (volume brut d'eau irréductible) et la pression capillaire, est élaboré par étalonnage du BVI dérivé de la RMN avec les données centrales, ledit nouveau modèle de transformation utilisant les modèles SBVI (BVI spectral) et/ou CBVI (BVI à interruptions) afin de rapporter directement les réponses de BVI dérivé de la RMN et de pression capillaire au moyen de la hauteur d'une mesure dans un puits de forage. Le modèle de transformation BVI dérivé basé sur la hauteur est appliqué au diagraphe RMN du puits de forage afin de quantifier les eaux non exploitables dans le diagraphe MNR.
