Geological Principles of Integrated Static Reservoir Modeling

Audience

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).

Content

Following the introduction of the static modeling process, each of the data input streams is 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 take place over the 5 days of the course:

  • Static Reservoir Modeling Overview: Explanation and discussion of the modeling process
  • Fault and Fault Seal Analysis: Recognition of faults in seismic and core, fault displacement models, fault seal analysis
  • Stratigraphic Analysis: core- and log-based sequence stratigraphy; seismic stratigraphy; biostratigraphy, chemostratigraphy, magnetostratigraphy, pressure data, residual salt analysis
  • 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
  • Reservoir Body Characterization: Depositional models; sandbody architectures; geological analysis of seismic sandbody analogues (ancient and modern) with examples from the FRL analogue database (ERGOTM)
  • Petrophysical Characterization: Review of petrophysical logging tools (conventional and advanced); Archie and non-Archie formation evaluation; conventional and special core analysis; seismic attributes and seismic inversion

Learning Objectives

  • Understand the modeling process
  • Identify faults and understand displacement and sealed faults
  • Use a variety of disciplines to conduct stratigraphic and facies analysis
  • Model depositional environments and sandbody architectures
  • Integrate petrophysical data from logs, formation evaluation, core analysis and seismic data
