For the oral paper ´Dynamics of stick-slip sliding induced by fluid injection in large sandstone block´, presented at the 80th EAGE Conference & Exhibition, Copenhagen 2018.

Injection of waste water underground can induce slip on critically-stressed faults, releasing stress built-up over many years and causing earthquakes. A similar problem might occur with the underground sequestration of carbon dioxide. In research supported by the U.S. Department of Energy, the authors designed a laboratory experiment to investigate this phenomenon, in which fluid injections close to an artificial interface of about 1 m length in a sandstone block were observed to induce sliding. Their presentation of the experimental setup and analysis of the resulting acoustic emission (AE) data is very clear. Analysis of the spatial distribution of the AE energy revealed the dynamics of stick-slip, indicating a nucleation phase of the sliding, then propagation of the rupture through the whole interface with an average rupture velocity of a few m/s. The speed and energy radiated during this event were approximately six orders of magnitude larger than observed during quasi-static sliding preceding the stick-slip. They conclude that the observed stick-slip motion is a laboratory analogue to earthquakes, and its occurrence can be related to the injection of fluids. 

 

Past Winners of the Guido Bonarelli Award

2018 Maksym Kryvohuz

For the oral paper ‘Source-side Up-down Wavefield Separation Using Dual NFHs’ presented at the 79th EAGE Conference and Exhibition 2017, Paris, 12-15 June, Extended Abstracts, Tu A4 06

The authors of this very clear paper present a method to eliminate sea-surface reflections from nearfield hydrophone measurements using additional near-field hydrophones. The far-field signature of an airgun array may then be calculated on a shot-by-shot basis from the near-field hydrophone measurements without corruption from sea-surface reflections. The method was demonstrated on synthetic and real data. Elimination of the source-side sea-surface reflections extends the bandwidth of the seismic reflection data, which is especially important at low frequencies. 
2017  Michele De Stefano 

For his oral paper ´Simulating geophysical models through fractal algorithms´, presented at the 78th EAGE Conference & Exhibition, Vienna, 30 May - 2 June 2016, Extended Abstract We SBT4 12.
From the computer-graphics industry De Stefano borrows the diamond-square algorithm, which has its roots in fractional Brownian motion, and which can be used for efficient, low-cost generation of randomised realisations of 2D and 3D geophysical models. The realisations are produced by iterated interpolation steps, alternating between nested square and diamond meshes and using additive white Gaussian noise and an appropriate Hurst exponent, to generate random values at an appropriate scale. The output realisations respect the original starting seed values. While this paper presents work in progress, it is both innovative and promising in its potential benefits to uncertainty simulation, and to interpolation and upscaling within modelling and inversion algorithms.

2016  Joe Zhou  And co-authors Peter Chia, Jingyu Li, Henry Ng, Sergey Birdus, Keat Huat Teng, Ying Peng Phan, Jason Sun and He Yi
For their oral paper ´Unlocking the full potential of broadband data with advanced processing technology, a case study from NWS Australia´, presented at the 77th EAGE Conference & Exhibition, Madrid, 1-4 June 2015, Extended Abstract We N103 13.
In this high-impact oral paper, Zhou et al. describe a broadband seismic case study from the Australian Northwest Shelf in which a combination of a twindepth airgun source array and twelve, 6-km slanted-depth cables were used to acquire a data set in which both the source and receiver ghost notches were substantially removed. The paper compares the performance of three methods of source signature estimation as well as two approaches to receiver deghosting. De-signature from near-field hydrophones proved most effective, while a method using sparse inversion in the 3D-Radon transform domain gave good 3D deghosting at the receivers. With a 3D attenuation-tomography method to estimate and compensate for Q, the authors show broad-band data that are almost flat to 160 Hz in the shallow section and that display excellent visual resolution in the deeper section. 
2015  Mike Warner 

And co-author Lluis Guasch
For their oral paper 'Adaptive waveform inversion – FWI without cycle skipping – theory', presented at the 76th EAGE Conference & Exhibition, Amsterdam, 16-19 June 2014.
In this first of two, innovative, companion papers, Warner and Guasch reformulate the conventional full-waveform inversion (FWI) algorithm so that it adapts predicted data to observed data using Wiener filters and then iterates the model by forcing the Wiener filters towards zero-lag delta functions. The authors show their adaptive FWI scheme to be immune to cycle skipping, a key issue in waveform inversion, and to invert, successfully, data for which conventional FWI fails entirely. Being robust to cycle-skipping, the new method does not require iteration from low-frequency components in the data or a highly accurate starting model. Adaptive FWI has some features in common with wave-equation migration velocity analysis (WEMVA) but it is applicable to all arrivals, including multiples and refractions, and does not incur the high-computational costs of 3D WEMVA.

2014  Kanglin Wang  And co-authors Paul J. Hatchell, Carsten Udengaard, Ken Craft and Shaun Dunn
For their oral paper 'Water velocity and tide measurement in marine seismic acquisition' presented at the 75th EAGE Annual Conference & Exhibition, London, 10-13 June 2013.
Spatial and temporal variations in water velocity and tides significantly impact the non-repeatability of marine time-lapse seismic data, and adversely affect the quality of 4D data processing. To reduce such variations the authors have developed a seafloor device called Pressure Inverted Echo Sounder (PIES) that provides direct measurements of water velocity and tides during seismic data acquisition. Placing PIES units at multiple locations enables determination of lateral and vertical water velocity profiles. A recent field trial conducted during a 4-month ocean bottom nodes survey demonstrated that PIES provides continuous measurements of average water velocities and tides, which are consistent with temperature-pressure-conductivity measurements and oceanographic data from nearby stations.
 2013 Lars Wensaas  And co-authors Marita Gading and Helge Løseth
For their oral paper entitled ‘Exploratory Approach to Fractured Reservoir – A Case Study in a Brazilian Field’ presented at the 73rd EAGE Annual Conference, Vienna, 23–26 May 2011.
This fracture analysis of non-conventional reservoirs was conducted during the exploration phase of a fractured Albian carbonate oilfield, located in the Campos Basin, in the eastern Brazilian continental margin, using a limited number of wells. The study aimed at understanding the lithological, diagenetic and mechanical controls of fracture distribution and their relationship with faults and salt domes mapped on seismic data. Geometric and kinematic analyses, in addition to structural evolution work carried on during this study, were fundamental to establishing the correlation between fracturing and regional deformation. The importance of a conceptual structural geologic model, especially in cases where it is not possible to perform a 3D numerical model of fractures is highlighted in this work.

For their oral paper entitled “South Atlantic Kinematics and The Evolution of Tristan da Cuhna Hotspot Tracks” presented at the 72nd EAGE Annual Conference, Barcelona, June 2010.
The authors documented the relationship between the formation of the Tristan da Cuhna hotspot tracks and the opening of the South Atlantic Ocean basin, particularly as continental extension ended
and oceanic crust began to form. The presentation could help us understand the role of magma sources and crustal evolution. The authors examined seafloor spreading magnetic anomaly profiles and
calculated new reconstruction poles for the South American and African plates and then used the results of a basin-scale 3D density inversion to compare the evolution of the Rio Grande Rise and Walvis Ridge hotspot tracks from ~130 Ma to 10 Ma.
2010  Laurent Sirgue  And co-authors Olav I. Barkved, Jean-Paul van Gestel, Ole Joran Askim and Jan Henrik Kommedal
For their oral paper entitled “3D Waveform Inversion on Valhall Wide-azimuth OBC”, presented at the 71st EAGE Annual Conference, Amsterdam, June 2009
The authors used full waveform inversion of wide azimuth field data from the Valhall Field and were able to extract much higher resolution velocity models than was previously possible. This greatly improves the quality of depth migration, and is itself a valuable interpretation attribute. The paper was judged to be a break-through.
2009  Michael Warner  And co-authors Ivan Stekl and Adrian Umpleby
For their oral paper entitled "Efficient and Effective 3D Wavefield Tomography", presented at the 70th EAGE Annual Conference, Rome, June 2008. The authors demonstrate 3D wavefield tomography applied to surface-streamer seismic data and obtain a result which appears to remove the distorting effects of shallow high-velocity channels. The methodology is of wide general applicability and the paper was judged to be a break-through.
2008  Erik Monsen  And co-authors Hilde Borgos, Pierre Le Guern and Lars Sonneland
For their oral presentation entitled “Geological Process Controlled Interpretation Based on 3D Wheeler Diagram Generation”, presented at the 69th EAGE Conference & Exhibition in London, UK, 11 to 14 June 2007.
The authors describe the automatic generation of interactive 3D Wheeler diagrams to capture the geological context and integrate it into 3D seismic interpretation. The work has been judged to represent a major breakthrough.
2007 Yu Zhang  And co-authors Sheng Xu and Guanquan Zhang
For their oral presentation entitled “Imaging Complex Salt Bodies with Turning-Wave One-Way Wave Equation Migration“, presented at the 68th EAGE Conference & Exhibition in Vienna, Austria, 12 to 15 June 2006. The authors presented a modified version of the one-way wave equation migration that can propagate wavefields to any possible direction, with true amplitude corrections. This enabled properly imaging of turning waves and hence the imaging of complex salt structures. The work has been judged to represent a major breakthrough.
2006 Karel Maron  And co-authors Stephen Bourne, Krijn Wit and Peter McGillivray
For their oral presentation entitled "Integrated reservoir surveillance of a heavy oil field in Peace River, Canada", presented at the 67th EAGE Conference in Madrid, Spain, 13 to 16 June 2005.Through an extensive reservoir-surveillance programme involving seismic time-lapse, continuous microseismic and surface tilt meter data acquired over several years, the authors were able to advance the understanding of dynamic behaviour of a heavy oil reservoir produced by cyclic steam stimulation. The work led to significant production improvements and has been judged to represent a major breakthrough.
2005  Yanghuah Wang  And co-author Michael Warner
For their oral presentation entitled “Fully data-driven and robust techniques for seismic multiple attenuation”, presented at the 66th EAGE Conference in Paris, France, 7 to 10 June 2004. The authors develop a data-driven concept for predicting multiples without explicit knowledge of surface and sub-surface structure or of the source signature, and a second robust concept for attenuating the predicted multiples without affecting the primaries.The combination of the two innovative concepts is demonstrated to work effectively, promising considerable potential for attenuation of multiple energy in both marine and land environments.The work has been judged to represent a major breakthrough.
2004  Paul Hague And co-authors Rob Staples, Toon Weisenborn and Peter Ashton
For their paper entitled "4D seismic for oil rim monitoring" presented at the 65th EAGE Conference in Stavanger, Norway, 2 to 5 June 2003. The authors use time-lapse seismic modelling and real data to unravel the complex and un intuitive response of a moving oil-gas-water triplet, enabling a significant addition to a field's recoverable reserves. This work has been judged to represent a major breakthrough.
