*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.

Topics of interest include:

  • Laboratory measurements of hydromechanical properties of rocks 
  • Theories of poroelasticity
  • Effective medium theories 
  • Pore-scale numerical simulations 
  • Computations of effective mechanical or hydraulic properties 
  • Numerical upscaling approaches
  • Attenuation and velocity dispersion caused by pore-scale phenomena 
  • Studies based on images (e.g., SEM, X-Ray micro-CT) of the rock microstructure 
  • Interpretation of borehole pressure transients considering the hydromechanical coupling 

Manuscripts must be uploaded using the Geophysics online submission system (https://mc.manuscriptcentral.com/geophysics) and will undergo the standard SEG Geophysics review process, which includes a double-blind peer review by three reviewers.

Special Issue Title: "Rock-physics - From microstructure to seismic signatures"

Special Issue Title: "Rock-physics - From microstructure to seismic signatures"

Call for Papers:


This special issue invites contributions which make novel theoretical, experimental and applied developments within the field of rock-physics. We invite extended and updated versions of papers published at the recent 4th International Rock Physics Workshop in Trondheim, as well as submissions from anyone presenting new, innovative results in the field of rock-physics. 

Rock-physics has received increased attention in the last decade due to the revolutionary exploitation of energy resources from unconventinals (shale gas, oil shales, tar sands). In particular, the investigations of nano- and micro-scale features of these types of reservoirs have proven to be an important part of the successful production of oil and gas from these plays. Also in the last decade, quantitative interpretation (QI) workflows where rock-physics constitutes a fundamental part, have become standard procedures in the petroleum industry. 
 
One of the big challenges in rock-physics, is to bridge the gap between the different scales, from nano- and micro scale, where most of the experimantal work is done, to the well log and seismic scale, where most of the applications are made. Also, with recent applications of seismic geomechanics, there is a need to better understand the relationship between static and dynamic rock physics properties. One of the key topics of discussions at the 4IRPW in Trondheim, was whether we are able to honor fundamental rock physics in our integrated and upscaled QI workflows. With recent focus on machine learning and big data analysis, there is also a question of the future role of rock-physicisits, and how we integrate rock physics with computer science. 

Suggested Topics:

We encourage the submission of papers covering different topics, from pure, fundamental research to more applied demonstrations and integrated case studies. More specifically, we suggest the following topics:

  • Fluid effects on rock physics: Dispersion (from sub-seismic to ultrasonic), attenuation and saturation dependenc
  • Geological processes and rock physics 
  • Rock physics of unconventional reservoirs
  • The impact of geomechanics on rock physics and vice versa
  • Novel laboratory techniques
  • Integrated use and analysis of multiple measurement techniques (elastic, electromagnetic, NMR, and others)
  • Fractured rock physics and anisotropy
  • Up- & down-scaling
  • Quantitative interpretation using rock physics and/or machine learning
  • Time-lapse seismic applications
  • Shallow / near-surface rock physics for environmental and geohazard studies
  • Deep crustal and geothermal applications

Submissions: 

Contributed papers are welcome to be submitted to “Geophysical Prospecting” by normal procedure via the Scholar One system (https://mc.manuscriptcentral.com/gp), but notify upon submission the title of the Special Issue: "Rock-physics - From microstructure to seismic signatures".

SEG postconventional workshop - W14: “Evidence and understanding of frequency and scale dependencies of rock properties: Fabric, textures and rock physics modelling at reservoir scale”

posted Jun 10, 2017, 10:18 AM by IARP Admin   [ updated Jun 10, 2017, 1:33 PM ]











Dear all,


The organizers of W14 workshop will run a Postconventional Workshop at SEG annual meeting on Friday 29 2017  


W14: “Evidence and understanding of frequency and scale dependencies of rock properties: Fabric, textures and rock physics modelling at reservoir scale

 

Syllabus:

The ultimate goal in geophysics is to characterize subsurface rock properties and fluid content at different scales.  The understanding why petrophysical properties of rocks are different at different scales and how to use them correctly in upscaling are crucial for reservoir modelling. In this workshop, we will review the current state of the understanding of the scale and time dependency of multi-physics properties of rocks.  The following themes are expected to be addressed from both theoretical and experimental point of view: variations of rocks lithology, porosity, permeability at micro, core, borehole and reservoir scales; rock mechanical properties variations including a difference between static and dynamic moduli, elastic moduli and attenuation dispersion; upscaling from micro to reservoir scale.

 

 

If you want to contribute to this topic, please send proposed title and a short abstract to PCW organizers: Maxim Lebedev (Curtin University)  M.Lebedev@curtin.edu.au ,  Mark Chapman (University of Edinburgh)  Mark.Chapman@ed.ac.uk , Erik Saenger (Ruhr-Universität Bochum) erik.saenger@rub.de , Vadim Lisitsa (IPGG) lisitsavv@ipgg.sbras.ru , Ran Bachrach (Schlumberger) rbachrach@slb.com

 

Please note that the speaker at this workshop will get 50% discount off the workshops. If registered before July 1st.

This year there is an opportunity to have your workshop abstracts published to SEG Digital library. Of course this is optional.

The list of workshops is available at the SEG annual meeting website:
