Abstract
Permeability and porosity are two important parameters to evaluate target layers in C02 sequestration. Because of the high cost of taking core samples from reservoirs and technology difficulties, well logging, a visual method without touching cores is often used to analyze the porosity and permeability. In this research, permeability and porosity values determined from well logging are compared with lab-measured porosity and permeability values, to identify a correlation. Based on reasonable matrix density assumptions, well logging-determined porosities can match well with lab-measured data. Due to experimental limitation, lab-measured porosities for some cores are lower than well logging-determined data. Cementation factor, m, has a significant effect on irreducible water saturation, Swirr, which is used to estimate the permeability of target layers. Base on reasonable assumptions of m and Swirr, well logging-determined permeability can match well with lab-measured data.
