Physical
Properties of Shale: The impact on imaging
September
18th & 19th 2006 at the NPD in
Shales are the most abundant sedimentary rock type,
with physical properties that play an important role in the recovery of
hydrocarbons. However, these properties
have not been investigated as extensively as those of reservoir rocks. Shale
may vary significantly in physical properties, and their relationship to petrophysical measurements is generally not
straightforward.
Understanding the elastic properties of shales
is important, since production-related changes in the acoustic properties of
thick shale layers effect seismic wave propagation. The effects of anisotropy on imaging are well
known in the seismic community. Anisotropy is also observed in resistivity measurements and may play a role in
electro-magnetic imaging. At present, the factors contributing to shale
anisotropy are often difficult to definitively isolate.
There is an increasing awareness that shale properties impact the
recovery of oil and gas both directly and indirectly. We wish to host a seminar
concerning the physical properties of shales,
focusing on the impact of these properties on imaging. Also discussed will be
rock-mechanics and dynamic changes in shale properties associated with
hydrocarbon production.
The seminar will focus on:
Imaging
Reservoir Characterization and 4D effects
Physical Properties of Shales:
Geological control of physical properties of shales
Pore scale properties
Acoustic and electrical properties (attenuation, anisotropy)
Transport properties
Pressure and stress / rock mechanical effects
A formal invitation and call for paper will be distributed in due time.
