Mainprice (Montpellier) Co-Convenor: Ernst Huenges (Potsdam) david@dstu.univ-montp2.fr huenges@gfz-potsdam.de The scope of the symposium is all aspects of the characterization of deep reservoirs. Laboratory, theoretical or field studies of reservoir rock properties at depth are welcomed in this symposium. The intensive exploitation of shallow reservoir systems for water, gas, oil and geothermal energy has resulted in a depletion of these resources. There is an increasing need to exploit the more financially demanding and technically difficult reservoirs at greater depths. The greater depths give rise in higher temperatures, pressures with more chemically reactive elements and increasing mineral plasticity, which until recently were mainly the concerns of academic "deep" crustal studies. Bore holes have been drilled in sedimentary sequences down to 9 km depth and in geothermal reservoirs down to 4 km. The characterization of reservoirs at these depths and their potential for economic exploitation require a more detailed knowledge of physical properties and their evolution with time at (high) temperature (e.g. permeability, thermal conductivity, kinetics of pore closure). The simultaneous measurement of several properties on the same sample or field region are encouraged. The presentation of new techniques which give new insights into the physical behaviour of deep reservoirs in more extreme conditions at are also welcome.

***** SYMPOSIUM ON *****
"COMPACTION, SUBSIDENCE, AND THE MECHANICS OF GRANULAR MATERIALS"
A key issue in geophysics is to understand compaction processes in
reservoir rocks. It is well known that hydrocarbon extraction reduces
pore pressure and thus increases effective stresses. Whereas the
accompanying compaction may result in improved oil recovery (compaction
drive), the price to pay will often be subsidence problems at the
surface, and well stability problems in the reservoir.
Despite recent advances in our understanding of the petrophysical
properties of granular reservoir materials, many fundamental aspects of
their behaviour during compaction remain unresolved. These include:
behaviour of overburden and arching effects, boundary conditions and
reservoir stress paths, behaviour of the reservoir rock mass on a
macroscopic scale, effect of inhomogeneities and fractures, response of
granular materials to fluids, temperature and effective pressure cycling
(water or gas injection), micromechanism of compaction at the pore and
grain level, influence of the rock microstructure, and chemical effects
at the fluid-solid interface.
The aim of the symposium will be to reveal the state of the art within
the subject, with emphasis on basic mechanisms and future developments.
One key issue of the symposium will be to bring together scientists
working at different scales (laboratory scale, reservoir scale), using
different approaches (experimental work, field studies, numerical
modelling) to study compaction and related effects.

Objective:
Solutions to coupled problems (thermal, mechanical, flow) have become
extremely important to understand unusual behavior of rock and rock

decade in a number of engineering disciplines. The Organizing Committee
feels that the time has come to exchange some concepts and ideas between
a number of disciplines and share common interests.
There are numerous coupled phenomena in subsurface engineering. However,
this conference focuses on the phenomena attributed to the coupling merely
between the solid mechanical impact and other mechanisms, such as (a)
fluid flow, (b) thermal transfer, (c) solute transport, and (d) any
combination of the above.
Theme:
The aim of this conference is to bring together theoreticians and
practitioners across geomechanics disciplines to discuss common
interests, differences, and potential collaboration.
Topics:
1. Mining Engineering
- Subsidence due to groundwater inrush into mining panels
- Extraction of coal bed methane from fractured media
- Influence of fluid flow on slope stability
- Protection of water resources
2. Petroleum Engineering
- Simulation of naturally fractured reservoirs
- Stress-dependent permeability and porosity
- Wellbore stability in poroelastic media
- Sand production and poroplasticity
- Shale stability related chemophysical and mechanical properties
- In-situ stress determination in porous media
3. Civil Engineering
- Soil consolidation in fractured porous media
- Subsidence due to pumping of groundwater
- Tunnel stability in conjunction with seepage flow and rock
deformation
- Multiphase fluid flow and solid deformation in partially
saturated vadose zones
4. Environmental Engineering
- Contaminant transport in deformable fractured media
- Impact of rock mechanics on pollutant containment systems
- Thermoporoelastic analysis of underground nuclear waste disposal
- Remediation of near-well contaminant in fractured rocks
