Research Report on Project 742-2 "Adjoint Method" Published

The 2nd phase DGMK 742 project was successfully completed. The aim was to develop a workflow based on the Adjoint Method that can be used to improve reservoir characterisation in the simulation model. The workflow now developed leverages the power of the above mathematical method (using SenEx software) to perform analytical sensitivity-based parameter changes at the grid level to reveal hidden reservoir properties such as preferential flow channels, uninterpreted faults, vertical communication, etc. Several detection algorithms have been developed during the DGMK 742/2 research project to improve the objective detection of hidden reservoir properties. The MEPO-tSenEx hotlink developed in phase 1 of the DGMK 742/1 project was also integrated into the workflow.

Within the framework of the DGMK 742/2 research project, the developed workflow and detection algorithms have been applied both, to synthetic as well as to some real field reservoir simulation models under various practical reservoir settings. Results obtained show that the developed workflow for improving reservoir characterization significantly outperforms other methods existing in literature. Numerous tests performed over the course of the DGMK 742/2 research project highlights benefits and limitations of using the developed workflow.
