Session Managers: Igor Escobar and Jorge Pita
In this session, we will be focusing on how we go about establishing and using petro-elastic models in the context of bridging across different disciplines and scales. The objective is to discuss in detail a range of topics using case studies and real data examples, including:
We will be aiming to identify common practices, most efficient workflows as well as missing technologies and tools.
Session Managers: Ann Muggeridge and Marie Ann Giddins
This session will cover the practical aspects of how best to integrate the modelling of geophysical response and reservoir fluid flow as a function of the subsurface geology. It will focus, in particular, on how to parameterise the physical processes and behaviours that cannot be resolved in the different models e.g. fluid distributions and their impact on petro-elastic response. Successful communication between the discipline models involves forward and backward transfers of data with differing resolutions and error bars in both space and time. Understanding the issues underlying gridding and parameterisation is essential for quantitative analysis. It can also be the key to effective communication between practitioners of different disciplines.
Discussions will include:
This session will prepare participants for the workflow investigations in Session III. We encourage contributions of real case study examples.
Session Managers: Pierre Thore and Mokhles Mezghani
Management of oil and gas fields depends upon accurate reservoir characterisation workflow. Better decisions/predictions can be made when multi-source data (geological, geophysical, production, etc.) are fully integrated in the reservoir description workflow. 4D seismic data now plays an important role in reservoir characterisation and management. As the technology matures, there is an increased emphasis on quantitative 4D interpretation to estimate changes in fluid saturation and reservoir pressure and the uncertainties associated with their estimation.
In this session we are investigating the various possible workflows:

3D and 4D geomechanical models are seeing a rapid up-take in the petroleum industry. The promises of usage of geomechanical models are alluring. These include improved prediction of reservoir quality, fracture location, orientation and properties, improved production forecasts by including stress-dependent fluid-flow properties, prediction of early water breakthrough by fault re-activation, optimisation of drilling trajecto ries, designing safe mudweight windows and prediction of well-bore instability. In this session, the speakers will discuss what data sources are used in building geomechanical models, how we know whether our geomechanical predictions are correct and, most importantly, what applications in field development planning 3D and 4D geomechanical models have been successfully used. Speakers are encouraged to show successful applications of geomechanical models, while pondering the question what shortcomings current workflows may have. How can close the-loop scenarios help to improve the building and calibration of geomechanical models?
Topics to be included:
Session Managers: Nigel Robinson and Francesca Pirera
This session focuses on the integration of 4D seismic data with other geophysical methods (for example, borehole seismic, microseismicity, geomagnetics, gravity), geological and/or engineering data to provide an improved understanding of a field development. Case histories from a variety of geological settings and environments will be presented to promote discussion on:
We are looking to discuss a range of case histories, for example:
