Geophysical Reservoir Characterisation (GPH01)

Description

Hydrocarbon reservoirs are described by site specific models representing all aspects of geometry, rock and fluid properties and potential hydrocarbon distribution. Modern reservoir characterisation aims for complete data integration, often with a strong bias on seismic data. Validated information is finally stored in a geo-cellular grid which is subsequently adapted for flow simulation.
To be integrated into the reservoir characterisation workflow seismic products need to be understood by reservoir geologists.
This course covers the seismic attributes most widely used for reservoir characterisation and demonstrates their application in reservoir modelling.
A nearly infinite number of seismic attributes is technically possible. Not all are useful, some are redundant, and other attributes work in specific situations only. Beyond the easy to calculate instantaneous attributes the advanced results from amplitude versus offset and amplitude inversions are discussed. It will be shown how to establish a link to borehole data and how to validate seismic derived information for reservoir characterisation.

Course Level: Intermediate
Instructor: Wilfried Gruber

Designed for you, if you are...

  • A geoscientist (all disciplines) who is exposed to reservoir description, characterisation and modelling

How we build your confidence

  • The methodologies presented are aimed to the point where seismic is incorporated into the geoscience workflow.
  • The course format contains theory, example cases from field studies and literature.
  • In practical examples you will use seismic attribute software to apply the methods taught, strengthen the knowledge gained, and set the basis for a maximum of seismic data integration in upcoming projects.
  • Throughout the course the level of detail in viewing the reservoir increases. It starts with seismic attributes giving field scale trends, moves on to integrating well data for resolving local features and finally embarks on statistical methods to be utilised on meter scale grid models.

The benefits from attending

By the end of the course you will feel confident in your understanding of:

  • The logic, underpinning assumptions and limitations of seismically derived information
  • How to select the seismic attribute required for a specific task
  • The applications of seismic data in a reservoir characterisation workflow
  • The benefits of data integration

  • Link well and seismic information
  • Attribute analysis and validation
  • AVO and fluid replacement analysis
  • Seismic inversion and the use of inversion results
  • Geostatistics for geophysical data integration
