   "This year's Annual Meeting will give attendees...a high- quality Technical Program with more posters." -Annual Meeting General Chairman, Ken Helm | | W-4 From Image to Insight: How Can We Leverage Pore-Scale Observations Through Rock Physics Models? Date: Thursday, 22 September
Time: 1:30 p.m.-5 p.m.
Henry B. Gonzalez Convention Center, Room 214 D
Organizers: Stephan Gelinsky and Ali Mese
Through the support of the SEG Research Committee Description: In parallel to the impressive advances in seismic imaging, our industry has made tremendous progress revealing ever more subtle details about the inside of our reservoir rocks and seals – down to the single pore and grain scale. For a while, established special core analysis techniques like capillary pressure, NMR, or XRD have allowed for a useful statistical effective medium description of pore space and rock matrix. This approach is now increasingly complemented by a variety of high resolution visualization techniques that include thin section analysis, SEM, and 3D X-ray micro CT imaging. Emerging technologies like nano indentation have started to contribute additional quantitative rock property information on unprecedented fine length scales. In this workshop, we will explore different approaches to leverage these pore-scale observations through rock physics models: - Now that we can see individual pore throats, grain coats, or micro-porous inclusions with unprecedented clarity – can we improve our approach to modeling rock stiffness or conductivity – and how do we ultimately provide better estimates of saturation and permeability from our remote sensing data?
- Now that we delineate heterogeneity on the finest scale and can virtually travel like a drop of oil through 3D digital images of tiny rock samples – how can we translate what we see into building more realistic and predictive models?
- How do we integrate our diverse micro-scale measurements and upscale our observations to length scales of operational interest?
- Especially when we are looking at heterogeneous carbonates or our intriguing shale gas and light tight oil resources: are our established rock and petrophysical models such as Gassmann or Archie still adequate - in light of what we have started to discover? What is next?
Our journey from 'image to insight' may be long and challenging, but it also looks promising and exciting!
