 W-15: Physics of Rocks SEG 2012 Annual Meeting Technical Program
Date: Friday, 9 November 2012
Time: 8:30 am – 4:00 pm
Location: Mandalay Bay Convention Center, Room: Breakers L
Organizers: Arthur Cheng, Ali Mese, Stephan Gelinsky, and Colin Sayers
Through the support of the SEG Research Committee
Description
As typically used in the oil and gas industry, the term rock physics is usually applied to the measurement, modeling, and interpretation of elastic wave propagation in sedimentary rocks. In contrast, this full day workshop will focus on the physics of rocks: how different detailed physical property measurements (electrical, flow, NMR, nuclear, etc.) of core samples can be used in combination with high resolution digital images of rocks to learn about the fundamental physics that control reservoir rocks and seals. Other questions to be discussed include the following: How are microscopic properties reflected in macroscopic measurements, and how can we improve our understanding of what drives important rock properties such as permeability, saturation, or stress response from a combination of complementary measurements? What can high resolution images really tell us? How can we parameterize these images in ways that can be used to characterize the rock, especially the geometric properties of the pore space, and not just the volume fraction of its constituents? The workshop combines four sessions, each with three presentations and ample time for discussion. Tentatively the sessions will be focused on the following topics: digital imaging, transport properties, multi-physics, and up-scaling.
