Module summary

The module introduces the purpose, problems and methods involved in creating a 3D geological (static) reservoir model which is the basis for dynamic modelling of hydrocarbon reservoir production.

Objectives

The module introduces the purpose, problems and methods involved in creating a 3D geological (static) reservoir model which is the basis for dynamic modelling of hydrocarbon reservoir production.

Learning outcomes
1. Awareness of the role and methods of 3D geologic (static) reservoir model generation
2. Familiarity with reservoir sedimentology and architecture descriptors and interpretation
3. Skills in sequence stratigraphic interpretation and well log correlation
4. Awareness of uncertainties associated with data acquisition, data type, data resolution, and impacts on reservoir modelling uncertainty – the need for iteration as new data become available
5. Awareness of economic (STOOIP and STGOIP) implications of uncertainties in reservoir volumetrics and quality.
6. Teamwork skills through a team-based reservoir characterization exercise


Syllabus

Setting the problem: Resolution of subsurface data; spatial resolution of all data types; limitations of 1D well data; problem of production and well placement planning on few data points (appraisal wells); need for iteration of reservoir models.
Reservoir sedimentology: Depositional elements (clastics); rock-typing in carbonates (primary, secondary diagenetic and fracture controls on pore network connectivity); alternative approaches to reservoir element definition.
Sequence stratigraphy as a methodology to constrain basin context and architectural framework: Sequence stratigraphy in well data and well to well correlations.
Towards a 3D geological (static) model: The modelling workflow (e.g. Cosentino); reservoir modelling elements – lithofacies, diagenetic, stratigraphic, structural (Bentley approach)
Reservoir modelling strategies and methods – significance of vertical and lateral heterogeneities at varying scales
Practical reservoir calculations using physical reservoir models. Practical reservoir calculations using physical reservoir models to illustrate (i) the effect of heterogeneity and anisotropy on reservoir calculations, (ii) the need for having representative values that characterise the reservoir, and ways of understanding the inter-well volume, (iii) the role of seismic data in reservoir calculations, and the errors induced by misinterpreting/mispicking reservoir horizons from seismic data, and (iv) how uncertainty in microstructural and flow properties both affect the calculated STOOIP or STGOIP values.
