Using PRM Data for Reservoir Management - An Interpreter’s View

In this study we will give an example from the user perspective on how PRM data are used in the daily work of the Snorre asset. The Snorre asset is organised teams assigned to particular fault blocks and reservoir management actions are discussed by these teams before actions are decided and taken. Together with downhole measurements, production and other field data, 4D data is regularly used in this context to complement the understanding we have of the reservoir. Time-lapse data acquisition with only a short time lag between the 4D surveys enables detailed correlation of actions taken for reservoir management with the 4D effects observed. Even small-scale actions like water or gas injection into particular stratigraphic zones can now be investigated. The values at stake when producing only one zone sub-optimally can be significant; and we will show an example for one well. Of course the same value potential cannot be assumed to be true for every well and every zone, but taking into account that the Snorre field has 66 active wells, each targeting several stratigraphic layers, this shows that the potential for value generation from PRM data is enormous.
