RokDoc Ji-Fi (Joint Impedance & Facies Inversion) - 2 Day Course - Training Course by Ikon Science

RokDoc Ji-Fi (Joint Impedance & Facies Inversion) - 2 Day Course

Available as a public course
Available as a private in-house course

Follow detailed workflows to become an expert in our most innovative inversion technology, starting from the generation of facies logs, through to running the inversion and QC of the results. As well as learning how to apply the software, all relevant underlying principles are discussed and results reviewed.

This course is intended for advanced RokDoc 3D users, and as such it is highly recommended that our RokDoc 1D2D Introduction course is attended first. Attendees will also greatly benefit from having been on our RokDoc 3D Reservoir Characterisation course as well.

Course outline

  • Overview of inversion principles, methods and application
