Characterization of Fractured Reservoir

Jon E. Olson

Predicting the performance of fractured reservoirs requires characterization of fracture length, spacing, height and aperture distributions.  Because none of these parameters are typically well constrained by available subsurface data because of small sample size (wellbores) or indirectness of the measurement (seismic), theoretical models are required to fully populate fracture networks for flow simulation.

The Effect of Particle Cementation on the Mechanical Properties of Granular Materials: A Fundamental Study

Jon E. Olson

Project Summary

The objective of the proposed study is to develop methodology for predicting strength and failure of particulate material, especially weakly cemented sand and gravel, from small-strain stiffness as measured with the velocity of stress waves. The project will be especially concerned with phenomena such as soil liquefaction in earthquakes and sand production in petroleum wells. The objective will be approached through the development of an improved, fundamental understanding of how particle cementation affects both the strength and the stiffness of cemented granular material.
