ERE6.4/EMRP1.71/TS2.5
Fracture, mechanics and flow in tight reservoirs
 
Convener: Richard Bakker
Co-Conveners: Auke Barnhoorn, Jan Borgomano, Ismay Vénice Akker
 



The presence of fractures, whether natural or induced, has become increasingly important in recent years in the exploitation of Earth’s natural resources. Especially in rocks that have a low matrix permeability, the presence of fractures is critical for reaching flow rates sufficient for economic hydrocarbon production and heat extraction for geothermal reservoirs. Better prediction of subsurface fracture arrangements and their mechanical and flow response have become an increasingly relevant field of research.
We propose here a multi-disciplinary session on the arrangement and mechanical evolution of natural and induced fracture networks and their response to fluid flow in low-permeability rocks on a multitude of scales (from pore-scale to basin-scale). We encourage submissions from experimental, numerical and field studies on fracture network formation and control on fluid flow of naturally and hydraulically fractured systems. Also studies that address the role of fractures on both shale gas and tight geothermal reservoir application cases are welcomed. We especially encourage early-career scientists to present their work in this session.

EMRP1.2
Advances in petrophysics and rock-physics: integrating models, laboratory experiments and field studies

Convener: Damien Jougnot
Co-Conveners: Ludovic Bodet, Lucas Pimienta


Geophysical methods have a great potential for characterizing subsurface 
properties and processes to inform geological, reservoir, hydrological, 
and biogeochemical studies. In these contexts, the classically used 
geophysical tools only provide indirect information about subsurface 
heterogeneities, reservoir rocks characteristics, and associated 
processes (e.g. flow, transport, biogeochemical reactions). 
Petrophysical relationships hence have to be developed to provide links 
between physical properties (e.g. electrical conductivity, seismic 
velocity or attenuation) and the intrinsic parameters of interest (e.g. 
fluid content, hydraulic properties). In addition, geophysical methods 
are increasingly deployed as time-lapse, or even continuous, and 
distributed monitoring tools on more and more complex environments. Here 
again, there is a great need for accurate and efficient physical 
relationships such that geophysical data can be correctly interpreted 
(e.g. included in fully coupled inversions). Establishing such models 
requires multidisciplinary approaches since involved theoretical 
frameworks differ. Each physical property has its intrinsic dependence 
to pore-scale interfacial, geometrical, and biogeochemical properties or 
to external condition (such as pressure or temperature). Each associated 
geophysical method has its specific investigation depth and spatial 
resolution which adds a significant level of complexity in combining and 
scaling theoretical developments with laboratory studies/validations 
and/or with field experiments. This session consequently invites 
contributions from various communities to share their models, their 
experiments, or their field tests and data in order to discuss about 
multidisciplinary ways to improve our knowledge on reservoir and near 
surface environment.

*Session description:

Carbon Capture (Utilization) and Storage CC(U)S technology encompasses injecting CO2 into deep geological formations, at specific sites selected for long-term (>10,000 yr), large-scale storage. CO2-injection may compromise the integrity of geological reservoirs due to the coupled Thermo-Hydro-Mechano-Chemical phenomena (THMCs) derived from CO2-fluid-rock interactions. Likewise, the scale problem, which is central for the characterization and monitoring of reservoirs during and after injection (e.g., seismic surveys), is typically linked to observations of reservoir properties derived from core and log data.

This session aims to highlight the importance of the THMCs processes, their scale dependency and the necessity of a unified understanding based on experimental and mathematical approaches. We welcome researchers to share their work on coupled processes including experimentation and/or modeling, and the application/development of direct/indirect measurement and tracking techniques. Particularly attractive will be those works addressing the incidence of THMC during CC(U)S.

Geophysics Call for Papers on Hydromechanical phenomena at the pore scale and their upscaling

Geophysics Call for Papers

Hydromechanical phenomena at the pore scale and their upscaling

This special section of Geophysics is dedicated to studies of hydromechanical phenomena at the pore scale which complement or extend the classical understanding of rock poroelasticity. In the process of upscaling coupled hydromechanical phenomena of fluid-saturated porous media, classical theories of poroelasticity neglect certain pore-scale effects, which may strongly affect geophysical acoustic measurements in the seismic-to-sonic frequency range. Hence, we propose to revisit the pore scale to explore poroelasticity in its full range of possibilities as well as to consider new upscaling approaches. We are aiming at a representative sampling of the latest advances in this area inspired and motivated by recent developments in a number of techniques. For example, advances in laboratory-based characterization techniques now enable well constrained investigations of frequency-dependent effects in fluid-saturated rocks. Advances in numerical techniques, combined with the continuous increase of computation power, allow for higher resolution and more accurate estimates of hydraulic and mechanical properties based on 3D image data sets of the rock microstructure or on stochastic distributions of microstructural features.

Ultimately, this special section aims at presenting current state-of-the-art developments in the research field and to stimulate interest not only among rock physicists but also among reservoir geophysicists. We invite researchers to submit original research articles, as well as review articles, covering theoretical, numerical, and experimental aspects.
