Field Development Plans rely on an accurate description of the reservoir geology. This requires integration of seismic and well data to build up a robust picture of the subsurface.
Reservoir characterisation studies include:
- depositional environment assessment
- facies identification
- wireline log interpretation
- core evaluation
- well correlation
- identification of flow units and barriers
The integration of geological studies with petrophysical and geophysical analyses yields conceptual reservoir models which can be encapsulated in geocellular models.
3D structural, facies and rock property modelling allows comprehensive uncertainty analysis, yields volumetric ranges and provides inputs to dynamic simulation models.
The models also provide the basis for designing development strategies, and hence feed directly into Field Development Plans.
