Geological Principles of Integrated Static Reservoir Modelling : 5 days

Who should attend:

This course should be attended by:

• Reservoir modellers who need to understand the diverse range and geological significance of data provided to them for the model build.
• Technical specialists who supply data to modellers and want to provide the best possible input data (e.g. geologists, geophysicists, petrophysicists, stratigraphers, engineers).

Overview:

This course is designed to identify and understand the geological interpretation and integration processes linking in to the structural, stratigraphic, lithofacies and object model components of a typical static reservoir model. This evaluation will lead to recommended approaches for incorporating greater geological understanding into static reservoir models. The course aims to establish a common language that better enables specialists and modellers to collaborate effectively.

Contents:

Following the introduction of the static modelling process, each of the data input streams will be reviewed in terms of the following: the available analytical methods; quality control issues; the integration of the analytical methods; key uncertainties with the combined methods, including strategies for dealing with those uncertainties

The following sessions will take place over the 5 days of the course.

1. Static Reservoir Modelling Overview: Explanation and discussion of the modelling process.
2. Fault and Fault Seal Analysis: Recognition of faults in seismic and core, fault displacement models, fault seal analysis.
3. Stratigraphic Analysis: core- and log-based sequence stratigraphy; seismic stratigraphy; biostratigraphy, chemostratigraphy, magnetostratigraphy, pressure data, residual salt analysis.
4. Facies Analysis: Facies analysis using cores and logs; constructing depositional models; constraining models with biofacies and ichnofacies; use of analogues in facies analysis; defining the most appropriate scale for facies; geological analysis of seismic.
5. Reservoir Body Characterisation: Depositional models; sandbody architectures; geological analysis of seismic sandbody analogues (ancient and modern) with examples from the FRL analogue database (ERGOTM).
6. Petrophysical Characterisation: Review of petrophysical logging tools (conventional and advanced); Archie and non-Archie formation evaluation; conventional and special core analysis; seismic attributes and seismic inversion.
