Evening Talk - "Digital Core Technology"
Mark Knackstedt - ANU
Monday 19th May, 6pm at Burlington House.
Abstract:
Digital core technology, 3D imaging and visualisation of core material at the pore scale and
subsequent analysis of petrophysical and multiphase flow properties can give important
insight to understanding properties of reservoir core material. Historically, digital core
technology has focused on the direct comparison of predictions with data collected from
conventional core analysis.
Results show that predictions of petrophysical and multiphase
properties from 3D image data (permeability tensor, formation factor, resistivity index,
relative permeability and drainage capillary pressure) are in good agreement with
experimental core measurements. Here we discuss some of the potential applications of this
emerging technology to the industry via case study examples including:
- Understanding reasons for scatter in petrophysical data in terms of rock type, pore structure and interconnectivity.
- Probing uncertainty in relative permeability data. Imaging and modeling of fluid distributions at the pore scale including the incorporation of different wettability scenarios.
- Direct imaging of reservoir compaction effects on porosity, permeability and pore
structure.
Biography:
Mark Knackstedt was awarded a BSc in 1985 from Columbia University and a PhD in
Chemical Engineering from Rice University in 1990. He is Professor and Head of the
Department of Applied Mathematics at the Australian National
University and a Visiting Professor at the School of Petroleum Engineering at
the University of NSW.
His primary focus is on development of 3D tomographic imaging
analysis methods and modeling transport elastic and multiphase flow properties of complex
materials. He leads the Digital Core Consortium Program. The consortium members include
ExxonMobil, Chevron, BP, Shell, Total, Saudi Aramco, Schlumberger, Baker Hughes, BHP
Billiton, Japan Oil and Gas, ADCO, ONGC (India) and Maersk Oil and Gas.
