Abstract

Porosity, permeability and capillary pressure data of 50 sandstone core samples obtained from the Tortel Formation have been used to evaluate reservoir quality. Three types of both reservoir rocks and capillary curves have been outlined. However, various correlation charts have been constructed in order to delineate porosity, permeability, pore throat size, recovery efficiency, height above the free water level and capillary pressure at different water saturation values of the reservoir rock. The used capillary pressure techniques are typically favored for geological and engineering applications for the development of sandstone pay zones of the Tortel Formation. The obtained charts could be used for determination of the important formation parameters and enhancing methods for reservoir development.
