BRUGGE Dataset
Brugge is a semi-synthetic oil field commonly used as a benchmark for optimizing waterflooding strategies and history matching. It was created by the Netherlands Organization for Applied Scientific Research (TNO) based on an existing waterflooded oil field.
Dataset structure
The structure of the Brugge field consists of an elongated east-to-west anticline with a major fault on its northern edge and an internal fault. Dimensions of the field is approximately 10 × 3 km². It is representative of Brent-type fields in the North Sea and consists of four primary zones: Schelde, Maas, Waal, and Schie.
Schelde
The Schelde zone has a fluvial depositional environment characterised by channel facie with favourable flow properties and shale impermeable facie. Object Modelling algorithm were used to generate facies of dataset and SGS for porosity-permeability. The input data for this process were well data.
| Modelling Approach | Object Modelling |
|---|---|
| Channel Width | [50; 550] |
| Channel Thickness | [5; 20] |
| Orientation | [200; 300] |
| Amplitude | [200; 1600] |
| Wavelength | [250; 2500] |
| Variogram Major for porosity | [1200; 1700] |
| Variogram Minor for porosity | [600; 1200] |
| Variogram Vertical for porosity | [1; 5] |
Maas
The next stratigraphic unit of the Brugge field is the Maas zone, which represents the Lower Shoreface depositional setting. The zone consists of sandstone facies with good reservoir properties and carbonate concretions. The most suitable algorithm for modelling such a depositional environment is SIS using well data.
| Modelling Approach | SIS |
|---|---|
| Variogram Major for sand facie | [500; 1500] |
| Variogram Minor for sand facie | [400; 1050] |
| Variogram Vertical for sand facie | [1; 6] |
| Variogram Major for porosity | [1500; 2600] |
| Variogram Minor for porosity | [500; 2000] |
| Variogram Vertical for porosity | [1; 4] |
Waal
The third stratigraphic unit has an Upper Shoreface depositional environment. It is characterised by good filtration and storage properties and is the best zone for development. This reservoir has a high thickness with an NTG up to 97 per cent, and the average permeability is about 800mD. When modelling such a reservoir, the most suitable algorithm is SIS.

| Variogram Minor for sand facie | [700; 900] |

| Variogram Major for porosity | [1000; 3000] |
| Variogram Minor for porosity | [500; 1500] |
| Variogram Vertical for porosity | [1; 6] |
Schie
The last lower zone of the Brugge field is composed of the Sandy Shelf sedimentary accumulation. This is a relatively thin layer with poor development parameters. The main feature of this zone is the irregular carbonate patches.

| Variogram Minor for sand facie | [200; 800] |
| Variogram Vertical for sand facie | [1; 6] |

| Variogram Minor for porosity | [600; 1200] |
| Variogram Vertical for porosity | [1; 6] |
Uncertainty parameters
- Porosity and permeability vary within each zone according to geological scenarios.
- Average permeability ranges from 36 to 1,100 mD.
- Average zone thickness ranges from 5 to 26 m, depending on geological features.
- Geometry of each zone varies depending on thickness, dip angles, and other stratigraphic parameters.
A total of 10,000 3D «cubes» of properties were created based on the Brugge model.
