Revealing the Petrophysical Properties of a Thin-Bedded Rock in a Norwegian Sea Reservoir With Logs, Core, And Miniperm Data

摘要

An unconventional thin-bed analysis based on logs, core, and miniperm data was needed to calculate the petrophysical proepr- ties of a reservoir under development in the Norwegian Sea. More than half of the reservoir section under investigation is composed of heterolithic facies: thinly interbedded sandstone and mudstone layers form one to several centimeters in thickness and of variable quality. By using miniperm measurements with 1-cm spacing on slabbed core, it was possible to resolve the properties of the rock far below the vertical resolution of conventional wireline logs and relate them to the bulk log measurements.
