Nigel Anstey Award

Best Paper Award for First Break
From 2012, the Nigel Anstey Award is to be presented to the author(s) of the best paper published in First Break in the calendar year preceding the award. The Anstey award will consist of a certificate and a specially bound copy of the issue in which the pertinent paper appears. This reallocation of the Anstey Award to a published paper continues the requirement that the contribution has a distinctly valuable and tangible bearing on one or more of the disciplines in our Association.

 

The Anstey Award 2016 is presented to


Andrew J. Cavanagh and his co-authors
R. Stuart Haszeldine and Bamshad Nazarian

For their paper ´The Sleipner CO2 storage site: using a basin model to understand reservoir simulations of plume dynamics´, published in First Break, volume 33, issue 6, June 2015, pp. 61–68

The Sleipner carbon capture and storage project has two decades of data and experience of geological carbon storage (GCS). This important paper integrates geophysics, geology, petrophysics and flow simulation to obtain a new insight into the controls on CO2 movement in the subsurface and the best approach to model it. Under gravity-dominated drainage, Cavanagh et al. show that Darcy flow modelling, applied for the first decade of Sleipner monitoring, gives a poor match to the fluid distribution inferred from 4D seismic. Instead, they propose a capillary percolation model, better suited to the drainage displacement of the wetting brine by injected CO2, under near hydrostatic conditions. With this
model, a significantly better match is obtained to the interpreted plume dynamics. Furthermore, the new approach is better able to address CO2 dissolution and suggests that, within decades, dissolution will make a significant contribution to storage. This significant paper generates a new flow simulation benchmark and will guide our thinking on GCS for years to come.

Previous Winners Of Nigel Anstey Award

Up until 2011, the Anstey Award was presented to a member of the Association who has made a contribution of distinctly valuable and tangible bearing on one or more of the disciplines in our Association, without being linked to a specific publication. The previous Award consisted of a medal and a certificate.

2015
Gwilym J. Lynn and his co-authors
A. Christian Ellis, Jonathan Brain, Richard Parker, Gerd-Jan Lörtzer and Sophie Michelet

For their paper 'Gannet F field – Unexpected fluid flow between reservoirs identified from time-lapse seismic data', published in First Break, volume 32, issue 4, April 2014, pp. 53-59

In this comprehensive, well presented case study, the authors have integrated time-lapse (4D) seismic data with high-resolution inversions, well data and geological modelling to constrain both static and dynamic flow models in the Gannet F field. The 4D data have revealed unexpected fluid flow between reservoir units, and have observed sweep in units without well penetrations, thereby constraining fluid distributions in space at discrete snapshots in time. The integrated interpretation has improved predictions of sand extent and reservoir quality and has identified undeveloped crestal volumes in southern reservoir units as future targets.
 

2014
Mai Westphal Stephensen and her co-authors
Michael Larsen, Gregers Dam and Tomas Hansen

For their paper 'The Glenlivet gas discovery – an integrated exploration history', published in First Break, volume 31, issue 7, July 2013, pp. 51-63.

The authors present a comprehensive case study showing the importance of careful integration of geological, petrophysical and geophysical data to de-risk an amplitude-supported stratigraphic play on the Glenlivet Prospect. The initial prospect definition was based on regional seismic mapping and evaluation of existing data from offset wells. The detailed analysis included petrophysical interpretation, porosity modelling, fluid substitution, and AVO modelling. The results were compared with seismic and attribute maps of the Vaila Formation in the Glenlivet area. Based on the integrated evaluation, a combined geological and geophysical risking of the identified prospect was performed, leading to the successful exploration well in 2009. The authors reviewed the prognosed and post-well results and investigated reasons for the observed deviations. The successful case study is important in that it may lead to further development of the West of Shetland gas basin

2013
Caroline E. Gill and her co-authors
Alberto Miotto, Mariano Floricich, Richard Rogers, R. David Potter, Josef Harwijanto and Peter Townsley

For their paper ‘The Nelson full field model: using iterative quantitative improvements from the initial framework to the final history match’, published in First Break, volume 30, issue 9, September 2012, pp. 43–53.

The authors present a powerful methodology for building and updating constrained reservoir models. Their method incorporates various datatypes, including well data, 4D seismic surveys and production history, into reservoir models by updating structural framework, macrofacies and petrophysical properties, while managing all datatypes within an integrated workflow. The authors demonstrate their technique with a complex, channelized reservoir in the Nelson field in the UK North Sea, with implications for production optimization in many other depleting NW European fields.

2012
Kurtis Wikel

For his paper ‘Geomechanics: Bridging the Gap from Geophysics to Engineering in Unconventional Reservoirs’, published in First Break, volume 29, issue 10, October 2011, pp. 71–81.

This paper argues that a geomechanics approach to tracking the stresses in the subsurface caused by drilling and hydraulic fracture operations in the production of unconventional tight gas and oil and gas shale reservoirs pays major dividends and should be more seriously considered in the geosciences community. The paper presents many topics of interest. Firstly, it is a very clear presentation of geomechanical concepts. This is excellent in the frame of a journal such as First Break, which will be read by people from very different technical horizons. Secondly, it discusses the impact of a geomechanical approach in the optimization of hydraulic fracturing in non-conventional reservoirs, which is also a very timely topic. And thirdly, it promotes a multidisciplinary approach, which is very topical for an EAGE publication. In all, a very good paper to introduce this recently redefined EAGE award.

2011
Ashley Francis

In recognition of his very substantial, original and diverse contribution to seismic inversion and geostatistics, and to the quantifying of uncertainty and risk. He has been a major influence for the widespread adoption of stochastic inversion technology in practical reservoir characterisation work. His extensive publications - especially his two papers in First Break - and lectures have helped considerably to publicise and also to demystify stochastic modelling, and to move it into the realm of an everyday tool in geological modelling. Thanks to the successful launch of his company Earthworks, he has successfully developed high speed stochastic inversion software to allow the rapid commercial application of the technique. Ashley Francis's other technical contributions, and his active participation in conferences define him as a geoscientist who has made a very major contribution to geoscience over more than two decades.

2010
Panos Kelamis

In recognition of his research in the complex area of land multiple estimation and removal, which has resulted in an impressive series of model-based and data-driven algorithms currently widely applied within the E&P industry. His extensive knowledge of both the theoretical and practical aspects of geophysics, and his high-quality contributions to the geophysical community in terms of more than one hundred journal publications, conference papers and workshop presentations, has made him one of the authoritive experts in this field. In the specific spirit of the Anstey Award, Dr Kelamis has always given special attention in the integration of data acquisition, processing and interpretation, linking together geophysical data of different nature (seismic, well logs, upholes etc.).


2009
No candidate was selected for the award this year.


2008
