Volume Velocity Modeling for Petrel

The Volume Velocity Modeling for Petrel TAP presents a workflow for building a geologically consistent velocity volume integrating the detail of the well velocity measurements with the spatial density of the seismic velocities.

The course covers a combination of theory and practical application of volume velocity modeling in Petrel.  It goes beyond basic functionality oriented “button clicking” software training by focusing on workflow implementation, on the automation of basic tasks and in the analysis of real cases using the customer’s data to focus on addressing immediate, particular problems.

Highlights of the course include:

  • Reduce the risk on exploration and development projects by building a solid velocity model integrating of all the available velocity information in a 3D geologic model using geostatistical tools.
  • Reduce the cycle time using Petrel workflow editor automated process.
  • A systematic, repeatable, auditable approach for increased confidence in results
  • Expertise beyond standard training
  • Validation of the workflow on client data
  • Adoption of the technology facilitated by Guru supported delivery

Development and exploration geologists, geophysicists, petroleum engineers, managers, reservoir engineers and technical personnel with prior experience in Petrel.
