In Grane, a 4D monitoring program was initiated in 2005 to map reservoir dynamics. After five bi-annual streamer monitors, a permanent reservoir monitoring (PRM) system was following the footsteps of a successful 4D story (Sinha Roy et. al. 2015) and installed in 2014 (Elde et. al. 2016). By end 2018 nine PRM acquisitions have been completed. The PRM data gives important dynamic information used in understanding of fluid movements, well planning, production management and as input to structural interpretation. These “fresh and frequent” high quality data are actively used to optimize new wells and updating the static and dynamic reservoir models. Fluid movement (i.e. gas) in order of ~0.5m can be observed.
