As in previous years dedicated sessions will be offered to complement the technical programme. The dedicated sessions will be open to all conference delegates.

This year’s technical programme will offer the following three dedicated sessions:

Low Enthalpy Geothermal Energy in North West Europe

Tuesday 17 June, 08:30 - 12:10 hrs (Part I), Room G 106

                             13:30 - 15:10 hrs (Part II), Room G 106

Conveners:  Mariene Gutierrez-Neri (EBN B.V.),  Rick Donselaar (TU Delft)

During the last decade an increased interest in the exploration for and the use of low-enthalpy geothermal in a number of European countries has resulted in many feasibility studies, research projects as well as the drilling of dozens of new geothermal wells. Typically, the targets are sandstone aquifers or carbonates at depths of 2000 to 3000 m, where temperatures between about 70 to 120 degrees prevail. Since often these same targets are potential reservoirs for oil or gas, there are both the risks for potential interference and the opportunities for synergy with hydrocarbon E&P activities. The exchange of data, knowledge and experience in the performance of aquifers and reservoirs between both industries is resulting in new ideas and practices.

This session seeks to bring together geoscientist and engineers from industry, government and academia involved in low-enthalpy geothermal energy in NW Europe. Contributions will be considered related to: 1) synergy between geothermal and oil and gas E&P, such as double-plays and knowledge and data sharing;  2) reservoir performance including productivity and injectivity issues, reservoir modelling, geochemistry, stimulation technologies, and geomechanics; 3) reservoir monitoring and management; 4) economic and environmental issues including legal aspects and financial boundary conditions for successful geothermal energy production.


HPC for Geoscience Applications

Wednesday 18 June, 08:30 - 12:10 hrs, Room G 102

Conveners: Philippe Thierry (Intel Corp.), Gunter Roeth (Bull S.A.)

Major progress has been made in the quality of seismic imaging and modeling by using fewer approximations in the numerical schemes, which exploit the new computer architectures. These computer innovations include multi-core processors, vector co-processors, larger memories and faster system interconnects.

Reaching high performance in Geophysics must remain doable for every end user or dedicated developer. Apart from the programing model question, it is important to keep in mind that already from the equations scientists need some hardware knowledge, as the basic concept of arithmetic intensity, or the architecture of the whole machine.

The purpose of this session is to review the current and future state of modeling & inversion implementations using these hardware innovations. Furthermore, we wish to present algorithms used for example in seismology, based on ray tracing, finite differences or spectral methods which can be adapted to improve the Oil & Gas processing in exploration.

Since the modeling engine is not the only part of the problem, we will also discuss forthcoming issues as communications and I/O already visible today in the inversion codes.

Handling huge amounts of data during the computations becomes a serious problem which is not restricted to Geophysics as we can see with growing number of publications around BigData. This will probably become a challenge for the even larger datasets when targeting fully elastic inversion or when pre-processing the prestack data.


The Use of Production Data in the Geologic Model

Thursday 19 June, 13:30 - 17:10 hrs, Room G 104

Conveners: Pierre Thore (Total EP UK) and Shiyi Zheng (London South Bank University)

This special session aims at collecting a number of case histories showing how integration of production data has had an impact on the definition of the geological model.

Integration of different disciplines is the key for better definition of the geological model. In the past this model has been the fruit of integration of geological information (mostly observation at well + geological concept) and geophysical data (interpretation of horizons for the structure and seismic inversion results for the infill) using various geostatistical techniques (two point geostatistics in the past and nowadays multipoint geostatistics). This model was then delivered to reservoir engineers who modified it according to dynamic data often without cross validation of geology.

In the recent years 4D seismic has brought a new paradigm to reservoir engineers who have obtained, for the first time, detailed information with a very high special coverage that they could/should take into account. This information results from the interaction of geology and production and this fact cannot be obliterated in the construction of the model representing the reservoir. It is therefore mandatory to integrate production data when available into the building of a geological model.

The integration of new data is not an easy task (e.g. due to scale issues) and this special session will focus on new practices that have been used to integrate geological, geophysical and production data in a consistent manner to built or update  a geological model. Theoretical issues as well as case histories would be considered and success stories as well as (relative) failure would provide valuable information to the geosciences community.
