Abstract - The paper discusses the characterization of a reservoir in terms of vertical oil-water saturation distribution using Leverett's 'J' function method. The work depicted in the paper is a part of the extensive project work carried out for the estimation of effective porosity, permeability and pore size distribution of BMS sand of Geleky field of Upper Assam Shelf North, Assam & Assam Arakan Basin in the year 2017-18 with the objective of integration of Lab data with Log data by determining primarily the effective porosity of the core plugs. The studies were also intended to reveal the pore size distribution framework of the cores and their effects especially in variation in irreducible water saturation (Swirr) of different cores of the same sand. The focus area of the paper is thedata derived from capillary pressure studies on the core plugs which are used to calculate the oil and water saturations at any height above the free liquid surface by incorporating Leverett's 'J' function.The profile thus drawn can be integrated with Logs for better characterization of reservoir and to fill up the gaps in the oil and water saturation profile wherever required.
