Uplifting the Pore Pressure Prediction Workflow in RokDoc: Getting it right by Infusing Rock Physics

This webinar will be presented live with local experts from Ikon Science to discuss the unique needs and challenges.

  1. Wednesday, Sept 14, 2pm MYT (Kuala Lumpur/Perth)
  2. Thursday, Sept 15, 2pm BST (London)/ 8am CST (Houston)

What we'll discuss:

The typical shale-based pore pressure prediction workflow has proven to be fit-for-purpose but largely unchanged for many decades. Commonly used models such as Eaton’s and Bower’s assume that changes in the measured log data relate directly to changes in pore pressure and contribute to the log response. However, further study and failed pore pressure predictions have provided additional rock-physics-related causes for the varying log response in shales that are independent of pore pressure. This presentation focuses on shale mineralogy, in particular how a high Clay Volume (VClay) could cause the log magnitude (e.g. Vp) to be reduced, mimicking a high pore pressure signature, which may or may not be present.

This webinar introduces the theory of VClay’s impact on Pore Pressure Prediction and how this can be addressed using RokDoc’s latest Rock Physics Model for Pore Pressure workflow, comparing it to the pore pressure from the traditional non-corrected normal compaction trend approach.
