A case for shale optimization
By K. McKennaKevin McKenna argues that with the large scale of drilling programmes common in today’s onshore shale plays, relatively small optimization of workflows in all stages of the field life cycles can have a dramatic multiplied effect on the economic viability of projects.

Novel noise reduction for time-lapse and AVO workflows
Authors E. Zabihi Naeini and H. MorrisEhsan Zabihi Naeini and Henry Morris describe with a 4D case study a novel technique for reducing the noise on each time-lapse dataset and also minimizing the inconsistencies due to different noise character across the datasets.

Value of broadband seismic for interpretation, reservoir characterization and quantitative interpretation workflows
Authors C. Reiser, T. Bird, F. Engelmark, E. Anderson and Y. BalabekovCyrille Reiser, Tim Bird, Folke Engelmark, Euan Anderson and Yermek Balabekov present a series of case studies to illustrate the performance of broadband seismic dual-sensor streamer acquisition and its positive impact across a range of E&P asset development phases from exploration to appraisal and field development/optimization.

Integrated time-lapse monitoring of a Morrow reservoir using multi-component seismic and flow simulation, Postle Field, Oklahoma
Authors N.A. Zerpa and T.L. DavisNataly A. Zerpa and Thomas L. Davis determine whether time-lapse multi-component seismic technology is applicable for not only identifying but monitoring the reservoir at Postle Field, Oklahoma under miscible CO2 water-alternating-gas (WAG) flooding for enhanced oil recovery (EOR).

Wanted and unwanted effects of surface seismic data resolution improvements
Authors H. Jędrzejowska-Tyczkowska and T.L. DavisHalina Jędrzejowska-Tyczkowska and Thomas L. Davis illustrate how seismic data resolution enhancement using borehole data can improve reservoir characterization with the caution that it must be carried out carefully.

Technical presentations in geosciences: what do we really understand?
More LessPaolo Dell’Aversana invites geoscience colleagues everywhere to acknowledge that technical presentations are by no means always fully understood and, based on some preliminary research, suggests that everyone from presenters, audiences, and conference organizers could contribute to the solution.

Orthogonal wide azimuth surveys: acquisition and imaging
Authors S. Baldock, C. Reta-Tang, B. Beck, W. Gao, J. Cai and S. HightowerWide azimuth seismic surveying is firmly established as a key element in subsalt exploration and production in the Gulf of Mexico. The challenge now facing the industry is to further improve subsalt images in areas with existing wide azimuth coverage. Orthogonal wide azimuth acquisition, acquiring a second wide azimuth dataset over existing wide azimuth data, is a technique that provides close to full azimuth coverage while utilizing existing wide azimuth data. A case study performed in the Gulf of Mexico demonstrates that the increased source and receiver illumination created by orthogonal wide azimuth surveys significantly improves imaging results and increases the effectiveness of the tomography and salt interpretation steps.

The Nelson full field model: using iterative quantitative improvements from the initial framework to the final history match
Authors C.E. Gill, A. Miotto, M. Floricich, R. Rogers, R.D. Potter, J. Harwijanto and P. TownsleyThe Nelson Field is a stratigraphically complex, channelized reservoir that has been in production since 1994 and is at the mid-mature stage of field life. The current management strategy is focused on identifying infill well locations with the aim of recovering bypassed oil. A key component to identification of such target locations is an accurate reservoir model to highlight unswept areas through simulation. To date, a number of generations of reservoir models have failed to history match. The causes of failure are poorly understood. Recent insights into both the static and dynamic behaviour of the field have led to the building of a new model in an attempt to understand the production performance. There are three key areas of change in the new static model: a new structural framework; a new macrofacies model; and the subdivision of petrophysical properties associated with that model. The model was improved iteratively using data from two discrete sources: seismic close-the-loop and dynamic history matches. The full field model has helped to evaluate a number of possible infill targets and has been used to aid in well and reservoir management to better manage the field performance.
