The workshop was held on Tuesday, May 8 and concluded on Thursday, May
10, 2012. All meeting sessions were held
at the Hilton Garden Inn in Laramie. For a complete agenda please click here.
This workshop consisted of presentations from research groups that have been funded by the Center for Fundamentals of Subsurface Flow
and contributed presentations. Short courses were offered on upscaling
in heterogeneous and fractured media and reservoir geomechanics.
Examples of topics covered by additional talks were:
- Recovery of
natural gas from unconventional reservoirs characterized by low
permeability. Namely, research activities that aim at improving the
current understanding of permeability distribution, connectivity, and flow
pathways that can be used to improve reservoir models and field design.
of greenhouse gas and associated impurities (GGI) in geologic formations, e.g.,
deep saline aquifers and oil and gas reservoirs. Namely, research activities
that aim at improving the current understanding of the underlying phenomena
responsible for various GGI geologic storage mechanisms that can be used to
develop or improve predictive modeling tools.

Title: Introduction to computational reservoir geomechanics
Abstract: The study of the coupling between geomechanics
and multiphase flows is becoming increasingly important in reservoir engineering
as deeper formations are detected and explored. During secondary recovery of hydrocarbon
fluid due to forced imbibition of water, changes in pore pressure trigger
perturbations in the mechanical equilibrium of the porous medium leading to
stress modifications which alter rock properties such as permeability and
porosity. Applications are widespread and involve compaction drive mechanism,
land subsidence, hydraulic fracturing, stress dependent permeability, pore
collapse phenomena, caprock integrity, wellbore instability, casing damage, sand
production, strain localization and fault reactivation. In this short course we
present the intriguing and fascinating historical developments of the theories
of poromechanics and their application to reservoir compaction and land subsidence
during fluid withdrawal. Starting from the classical models of Terzaghi
and Biot we evolve till the modern multiscale theories of multiphase flow in
strongly heterogeneous deformable media. Some discussions regarding the geomechanical
interaction between the reservoir and adjacent non-pay formations will
also be presented.

Title: Up-scaling and flow in heterogeneous
and fractured media
techniques were used at the very beginning of oil and gas reservoir simulation
in order to provide acceptable simulation times. Simultaneous improvements of
calculation capabilities and small-scale reservoir characterization by means of
geostatistical techniques maintain the interest in such techniques even with
today's computing power. This is particularly important in the context of
history matching or uncertainty analysis applications that are needed for
economic decisions or environmental constraints, and that need tremendous
computing resources. At present times, these "old fashioned" up-scaling
techniques can be considered as being a part of "multiscale
approaches" that are becoming a major sub discipline of
scientific computing. In the course, we will travel from old-fashioned
techniques to most recent approaches. Up-scaling of non linear transport
problems will be discussed, as well as up-scaling of fractured media. The
applications to history matching techniques will be discussed.
