The Louis Cagniard Award 2019 was presented to:

Anton Egorov
and his co-authors Andrej Bona, Roman Pevzner, Stanislav Glubokovskikh and Vladimir Puzyrev

For their poster 'A feasibility study of time-lapse FWI on DAS VSP data acquired with permanent sources', presented at the 80th EAGE Conference & Exhibition, Copenhagen 2018.

The authors tackle the problem of detection and monitoring of carbon dioxide storage in the subsurface. In a feasibility study using synthetic data, they show that it is possible to conduct permanent monitoring of injected carbon dioxide using a Distributed Acoustic Sensing (DAS) cable in the injection well and a small number of permanently-installed sources. Applying full waveform inversion (FWI) to the time-lapse data allows the movement of the carbon dioxide plume to be tracked, making quantitative interpretation possible within a few hours of data acquisition. They show the applicability of their idea on a full model of the Otway site in Australia. The work is innovative and has enormous potential to help ensure safe carbon dioxide storage.

 

Past Winners of the Louis Cagniard Award

2018 Bamshad Nazarian 

And co-author Philip Ringrose
For their poster ‘Risk Associated with Legacy Wells in CCS and CO2 EOR Projects; a Simulation Study’ 79th EAGE Conference and Exhibition 2017, Paris, 12-15 June, Extended Abstracts,Th P7 05
The authors of this excellent poster presentation use numerical reservoir simulation from realistic models of saline aquifers & depleted hydrocarbon reservoirs to determine the conditions under which legacy wells will create a risk leakage in large scale CO2 storage and CO2 EOR projects. The simulation study concluded that if Plug and Abandonment (P&A) is carried out on legacy wells the risk of CO2 leakage is negligible. Further, leakage would happen in abandoned wells when the average pressure has increased considerably during CO2 injection. Finally, they found that for infinite-acting reservoirs where the pressure build-up in the reservoir is negligible, CO2 intrusion through existing pass ways provided by legacy wells is limited.

And co-authors F. Descamps, B. Caline, S. Vandycke and R. Swennen
For their poster 'Tight chalks - how does microtexture affect petrophysical and geomechanical properties?', 78th EAGE Conference & Exhibition, Vienna, 30 May - 2 June 2016, Extended Abstract We P5 01.
The authors of this excellent poster presentation use detailed petrographical, poroperm and mechanical property analyses to characterise thirty-five outcrop samples of low-permeability, non-reservoir North Sea chalks representing a broad spectrum in porosity, pore-throat diameter and rock strength. Such chalks may be under-explored reservoirs or may play important roles in hydrocarbon migration and so their microtextures are important to understand. Controlling factors are the non-carbonate content, related to deposition or diagenesis, and the degree of cementation, established from scanning electron-microscope (SEM) observations. These impact pore throat and body size, in turn affecting poroperm properties and rock strength. The analysis suggests that nuclear magnetic resonance (NMR) well logging, especially if combined with SEM observations on rock-cuttings, should allow an accurate prediction of the petrographical, petrophysical and possibly geomechanical characteristics of tight chalks penetrated by the drillbit.

2016  Mojtaba Rajabi  And co-authors Mark Tingay, Oliver Heidbach and Rosalind King
For their poster 'The role of faults and fractures in local and regional perturbation of present-day horizontal stresses – an example from the Clarence-Moreton Basin, Eastern Australia', 77th EAGE Conference & Exhibition, Madrid, 1-4 June 2015, Extended Abstract Th P1 12.
Stress fields impact borehole stability and hydrofrac design. The Australian plate exhibits an anomalous stress field that is not aligned to the plate motion vector and so Rajabi et al. embarked on an integrated study of acoustic imaging logs, borehole breakouts and drilling-induced fractures from 27 coal-seam gas wells in the Clarence-Moreton basin. While they found a mean direction for the maximum horizontal stress of N68°E, there are significant local variations, both laterally and in depth, which they attribute to the presence of faults, fractures and contrasts in lithology linked to the local geology. The results are significant because they are the first basin-scale stress-map data from this region and the mean direction found is almost orthogonal from that predicted by numerical plate-scale models. Since hydrofrac stimulation is the most common coalseam gas completion, the results will have a major impact on well design and completion in the basin.

For their poster 'Using gas chimney detection to assess hydrocarbon charge and top seal effectiveness – offshore, Namibia', presented at the 76th EAGE Conference & Exhibition, Amsterdam, 16-19 June 2014.
Seismic data with shallow gas anomalies often display degraded imaging below, posing the question as to whether the deeper section constitutes an active migration pathway or simply poor imaging due to local velocity anomalies. The authors describe a study in deep water, offshore Namibia, in which the goal was to improve understanding of the petroleum system and to identify drilling prospects. Gas chimneys were detected on 3D seismic data using directional seismic attributes and neural networks trained by an interpreter. Interpreted chimneys were tracked to the corresponding gas sources, identifying the source rocks and helping to interpret migration pathways, potential reservoir charging and top seal integrity. The analysis suggests that, in a typical slope-canyon prospect, Middle Cretaceous source rock is providing a hydrocarbon charge to prospective Upper Cretaceous reservoir targets. Up-dip, an overlying gas cloud indicates hydrocarbon saturation in the reservoirs, from where the lighter components are leaking. If the migrating hydrocarbons are a mixed phase, the target reservoirs may be oil prone, an interpretation yet to be tested by a bit. Such a well presented, refutable hypothesis, presented clearly before drilling, is a scientific method at its best and judged well worthy of the Cagniard award.
2014  Maurizio Ferla  And co-authors Jeroen Jocker, Ferdinanda Pampuri and Erik Wielemaker
For their poster 'Seismic anisotropy characterization in heterogeneous formations using borehole sonic data' presented at the 75th EAGE Annual Conference & Exhibition, London, 10-13 June 2013.
The authors present a new inversion workflow that they successfully applied to determine the transversely isotropic elastic properties of heterogeneous sand-shale sequences using sonic log data, from two wells of differing deviations that were binned according to their petrophysical properties. The results of the workflow have significant practical implications. Synthetics based on the anisotropy-corrected deviated well logs should yield a significantly improved time-vertical depth relation and better well-tie correlations. Additional applications include the use of the inverted anisotropic parameters as inputs into anisotropic seismic velocity models and AVO analysis.
2013  Sergei Stanchits  And co-authors Aniket Surdi and Roberto Suarez-Rivera
For their poster entitled ‘Hydraulic Fracturing of Tight Shale Monitored by Acoustic Emission and Ultrasonic Transmission’ presented at the 74th EAGE Annual Conference, Copenhagen, 4–7 June 2012.
The authors study the effect of fluid viscosity on hydraulic fracture initiation and near-wellbore propagation on block samples of tight shales subjected to representative in-situ effective stress conditions. Firstly, they develop an understanding of the hydraulic fracturing conditions under controlled laboratory experiments and then extend this understanding to field processes. Their results provide a reference for practitioners in this important area to relate the viscosity of an injected fluid to the characteristics of dynamic fracture propagation and geometry.

2012  Catherine Wasse  And co-authors Philippe Heldens and Joost van der Burgh
For their poster entitled ‘NL-onshore – Donkersloot Prospect Example’ presented at the 73rd EAGE Annual Conference, Vienna, 23–26 May 2011.
The poster presents a classic exploration workflow from the Netherlands onshore area. Prospectivity is defined and analysed by systematic and integrated structural mapping, petroleum system analysis and basin modelling, along with reservoir mapping and seismic anomaly modelling. This workflow is a clear and positive example of exploration methodology and prospect de-risking and represents the type of day-to-day activities that many industry based geoscientists would be involved in. As such, it illustrates how knowledge and technology are used to bring exploration prospects forward. The poster and presentation were judged to be of exceptionally high quality and standard.
2011  J.I. Mars  And co-authors A.A. Khan, V. Vrabie, A. Girard and G. D’Urso
For their poster entitled “Water Leakage Detection in Dikes by Fiber Optic” presented at the 72nd EAGE Annual Conference, Barcelona, June 2010.
A method is proposed for the identification of leakages in dikes using the temperature data obtained through fiber optic distributed temperature sensors. The authors showed how it was possible to treat leakage identification as a source separation problem. The sources were considered as defining the response of the ground, the known structures in the path of the fibre sensors (drains), the seasonal variations, precipitation and, of course, the leakages, the last ones were being their desired signals. They showed that with the help of techniques based on data decomposition and source separation (by PCA and ICA techniques), the leakages could be identified.
2010  Daniel Barker  And co-author Martin Landrø
For their poster entitled “Controlled source strength variation by changing the firing pressure - A sensitivity study for 4D calibration”, presented at the 71st EAGE Annual Conference, Amsterdam, June 2009.
The authors conducted a modelling study to test a method for calibration of 4D seismic signals by varying the firing pressure of the air gun source. They also showed that the resulting bubble time period should not affect the result.
2009  Benoit Paternoster  And co-authors Danil Knyazev and Thierry DesVallieres
For their poster entitled "Robust use of AVO to Geohazard Assessment – South-east Asia Gas Field Case Study", presented at the 70th EAGE Annual Conference, Rome June 2008. The authors used an innovative AVO approach incorporating automatic screening of the volume to assess geohazards associated with shallow gas. It cross-validated the AutoGasRisk methodology with geological interpretation.

Fortheir poster presentation entitled “Permanent Fiber-Optic Borehole Seismic Installation and Imaging at Valhall”, presented at the 69th EAGE Conference & Exhibition in London, UK, 11 to 14 June 2007.
The authors describe the first successful installation of a permanent borehole seismic system in an offshore production well. It employs fibre-optic communications and is being used for both active and passive surveys, giving high resolution images up to 400m from the borehole and offering the possibility of time-lapse monitoring of fluid fronts. This work has been judged to represent a major breakthrough.
2007  Isabel Varela  And co-authors Mosab Nasser, Mark Chapman and Enru Liu
For their poster presentation entitled “Anisotropic Azimuthal Attenuation as an Indicator of Fracture Properties, a Case Study on Time-Lapse Walkaround VSP Data”, presented at the 68th EAGE Conference & Exhibition in Vienna, Austria, 12 to 15 June 2006. The authors characterized fractures by analyzing a time lapse walkaround, multilevel VSP data set from a carbonate field in Oman with a long history of steam injection and production. They compared changes in traveltime and attenuation in response to fracture orientation. This work has been judged to represent a major breakthrough.
2006  Stéphane Operto  And co-authors Jean-Xavier Dessa and Jean Virieux
For their oral presentation entitled "Crustal seismic imaging from ocean bottom seismometer data by full waveform tomography", presented at the 67th EAGE Conference in Madrid, Spain, 13 to 16 June 2005.
The authors presented the first 2D full waveform inversion of dense real OBS data to generate deep images of a subduction system. Using parallel direct factorization for solving the frequency-domain visco-acoustic wave equation, they were able to image major thrusts at depths between 5 km and 15 km. The methodology offered impressive efficiency gains and has been judged to represent a major breakthrough.
2005  Brad Artman  And co-authors Deyan Draganov, Kees Wapenaar and Biondo Biondi
For their poster presentation entitled “Direct migration of passive seismic data”, presented at the 66th EAGE Conference in Paris, France, 7 to 10 June 2004 Through a formulation that relates transmission response to the reflection response for passive seismic data in a general 3D heterogeneous medium, the authors develop a methodology for calculating the reflection response and are then able to apply many of the conventional reflection techniques and to carry out various processes for preparing and enhancing the data and performing efficient migration for imaging the subsurface.This work opens the possibility of the development of more advanced imaging conditions and has been judged to represent a major breakthrough.
