The Use of Production Data in the Geologic Model

Convenors P. Thore (Total E&P)

This special session aims at collecting a number of case histories showing how integration of production data (including 4D) 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.

Several successful examples have already been published in the special session “use of production data in the geologic model” during the last two EAGE annual meetings. This year we would like to emphasize how conflicting information provided by the different disciplines have been reconciled and how remaining uncertainties have been handled. This session should provide hints to answer the question: are multiple realizations of the geological model the way forward?
