Reservoir Modeling

We build quality static reservoir models for clastic or carbonate reservoirs. Our models are focused on helping you make business decisions and contain the exact level of detail that is necessary to capture all the reservoir heterogeneities that are significant for fluid storage and flow. Uncertainty in input and output parameters is captured at every step of the process. We carefully plan the workflow at the start of the project to meet all the objectives in realistic timeframe.

 

Advantages of working with us for your reservoir modelling needs:

  • We do not work in isolation. From the start we collaborate with your team to deliver high quality integrated product
  • The model you get will be fully representative of the reservoir and fit for simulation, not unnecessarily geologically detailed and complicated
  • We are very careful and organized about the input data (no garbage in)
  • We use potentially multi-scenario mixed deterministic and probabilistic approach to deliver a geologically sensible reservoir model while capturing all the uncertainties
  • Cost effective on time delivery of high-quality products with satisfaction guarantee

 

We have experience in building reservoir models or inputs for reservoir models in:

  • Deep water Gulf of Mexico
  • Volga-Urals, Russia
  • Algeria
  • Offshore Newfoundland
  • Offshore Guyana

 

Structural Model

Horizon and fault interpretation from seismic will be reviewed and used to create a reservoir container grid. Uncertainty in the position of the surfaces due to depth conversion, well to seismic tie and interpretation will be captured. Horizonal cell dimensions and orientation will be determined. Here, we also consult the reservoir engineer to create a plan for upscaling later on from geomodel to simulation scale.

 

Stratigraphic Model

Structural grid will be subdivided into stratigraphic zones based on internal reservoir framework from seismic and wells as well as analogue reservoir concepts. The model will be layered, facies and reservoir properties will be upscaled to layer thickness scale. The layer thickness will be carefully selected to capture all reservoir heterogeneity significant to fluid flow. Several versions of layering are possible for later testing.

 

Facies Model

Reservoir porosity and permeability data from core and logs will be analyzed against the interpreted facies to determine if there are distinct reservoir property ranges that correspond to specific facies. If so, facies will be modelled across the grid using deterministic and stochastic methods. Uncertainty will be captured.

 

Property Model

Porosity will be modelled using deterministic and stochastic methods. Relationship between the permeability and porosity data from core and wells will be analyzed and permeability will be modelled via co-kriging or co-simulation with the porosity model. Saturation height function will be constructed and saturation will be modelled according to that function. Uncertainty will be captured for all reservoir properties.

 

Deliverables

Volumetric calculations. Sensitivity analysis. Uncertainty analysis. Well planning and placement analysis. The model will be prepared to be upscaled for simulation.

 

Our business model is directly dependent on the satisfaction of every client we serve and all possible effort will be taken to achieve that. Looking forward to working with you.
