Objective The aim of the project is to better identify and define migration pathways for oil and gas in 3D and to improve techniques to predict and visualise volumes of oil and gas in reservoir situations.This is achieved by combining two complementary software packages (dGB-GDI, i.e. a quantitative interpretation package, and SeisStrat-3D of IES, a seismostratigraphic-interpretation package) both widely applied as 2D packages. By completing a combined 3D version as one integrated software, the new package is able to perform an improved classification and quantification of lithological and stratigraphical parameters (e.g. determination of stratigraphic units, porosity or permeability) utilising seismic and well data. The new software package will focus on :- 3D seismic feature (attribute) extractions- local model confidence indication- increased accuracy of stratigraphic volume definition- utilisation of small scale lithological information with the help of real and stimulated wells.Furthermore, the more accurate 3D geological model of fluid pathways and of the distribution of reservoir storage capacity (which is a static observation) will be an asset for all dynamic modelling exercices simulating the processes of oil and gas migration and the formation of accumulations through geologic time. Following this line of thought, the application of the new software package for the case study will be greatly enhanced in value, when applying at the same time the 3D PetroMod simulator of IES, which is already completed. The complete software system will be installed in an operational environment with the E&P partner. There, it will be applied to validate the functionality in 3D in a real geological case study (probably for the North Sea)The project concerns the calibration and testing of a new set of seismostratigraphic mapping and regognition tools in combination with a 3D-simulation program for the generation and migration of oil/gas and its accumulation in reservoirs. A case study with real seismic and well log data from a basin structure will demonstrate the applicability of the combined dGB-IES modelling system. The seismostratigraphic tools enable the end-user to visualise, analyse, compare and recognise three-dimensional seismic bodies and their petrophysical parameters with greater detail and accuracy. The bodies are interpreted in terms of system tracts and lithofacies associations. The resulting interpretations are used :- to generate input for multiphase hydrocarbon generation and migration modelling packages.- to explore new areas and to identify new plays (notably stratigraphic traps)- to generate input for 3D modelling packages (like the new 3D version of PetroMod)- to generate input data for extended reservoir (incl. connected satellite structures) simulators, which can be used to increase the model resolution.- For oil and gas field development (i.e. drilling satellite structures etc.) It enables the geological dynamics of basin evolution to be taken into account, rather than being restricted to static present day geometry derived from classical seismic interpretation and well information as in a conventional reservoir simulation approach.The following objectives are defined for the project :- to find the optimal set of seismic features for characterising seismic bodies in 3D. - to find the best algorithms for supervised and unsupervised 3D seismic characterisation- to calibrate a neural network based technique, capable of estimating the target variable, the population as well as the modelling error.- to combine two complementary state-of-the-art interpretation systems so that the functionality of both packages can be used seamlessly to generate added synergy value by subsequent modelling capability.
