The formation sigma was used in the water saturation calculations. Spectroscopy analysis was also recorded and used for formation evaluation...

... helps to identify and assess the producible oil in a more appropriate way. This level may be determined by using fractional flow curves. In this case the contact level is a derived value for water saturation that relates to a specific water cut at surface conditions. If dynamic reservoir modeling...

... porosity and water saturation with core data showing excellent correlation does not ensure the correctness of petrophysical evaluations. In this paper, it has been demonstrated that there are potential problems associated with the integration of petrophysical evaluation and core data. Sources of errors...

In absence of core based J-function data, use of log derived initial water saturation helped in deciding the rock type distribution and saturation...

... solutions to calculate reservoir water saturation profiles from field water cut data are investigated. Different flow regimes and reservoir geometries are considered during this study. Diffuse, segregated and capillary influenced flow models are analyzed in both one and two dimensional water injection using...
