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.

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

posted Jul 3, 2017, 2:51 PM by IARP Admin   [ updated Oct 2, 2017, 11:48 AM ]

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


Contributed papers are welcome to be submitted to “Geophysical Prospecting” by normal procedure via the Scholar One system (, 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



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) ,  Mark Chapman (University of Edinburgh) , Erik Saenger (Ruhr-Universität Bochum) , Vadim Lisitsa (IPGG) , Ran Bachrach (Schlumberger)


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:

EAGE workshop: Rock Physics: The Essential Tool in Oil & Gas

posted Jan 15, 2017, 12:53 PM by IARP Admin   [ updated Jan 15, 2017, 12:54 PM ]

Rock Physics underpins much of modern Reservoir Modelling and Simulation.  Similarly, it is instrumental to intelligent Field Management.  In the broadest sense, it provides robust Theoretical, Experimental and Computational methods for maximising Value of Information, quantifying Risk & Uncertainty, and optimising Decision-Making, over the entire Field Lifecycle - in essence, it transforms raw data into essential Reservoir properties, and allows us to make rigorous predictions about Coupled Rock/Fluid behaviour in the presence of uncertainty.  As the Industry navigates through challenging Economic times, greater technical complexity, and into the era of Big Data, Rock Physics is set to take centre-stage in integrating and facilitating our understanding of the Subsurface.

Following the success of three previous workshops held in Dubai 2012, Oman 2014 and Istanbul 2016, EAGE is planning a fourth Rock Physics workshop to take place in Abu Dhabi, on 11 - 13 November 2017.   The past workshops witnessed a total of 70 presentations from around the globe, with different perspec­tives, including academia, research, oil companies and service providers, which really emphasized the sig­nificance rock physics has started to play in our everyday geoscience workflows. From frontier plays to field development and optimization, rock physics is now an entirely integrated science.

In this fourth EAGE workshop we will be further building upon the main theme of the role of rock physics in reservoir modelling and simulation. The theme encourages a showcase of studies and chal­lenges in the field-development life cycles, where rock physics has been integral.

Call for Abstracts is currently open for both oral and poster presentations, with the deadline for submitting as 15 April 2017.  The technical committee invites you to submit an abstract of 2–4 pages, on the following topics: 

  • Reservoir Modeling & Simulation
  • Geomechanics & Fracture Characterization
  •  Sedimentological Integration with Rock Physics
  • Carbonate Rock Physics
  • Experimental Rock Physics
  • Geophysical Petrophysics
  • Computational Rock Physics
  • AVA Seismic Data Conditioning & Inversion
  • Uncertainty Quantification
