Pore Pressure Modeling in Unconventional Resource Plays - 1 Day Course - Training Course by Ikon Science

Pore Pressure Modeling in Unconventional Resource Plays - 1 Day Course

Available as a public course

The purpose of this workshop is to discuss the importance of pore pressure modelling with specific application to unconventional resources.

Traditional pore pressure modeling techniques will be briefly reviewed, recognizing the uncertainties within these methods with specific applications to well planning. Modifications for unconventional plays which add to the pore pressure challenges will incorporate petrophysics, rock physics, and cross-validation with geomechanics. The day’s learnings will be applied to four case studies showing cost effective, safe drilling, and practical understandings of overpressure and those implications for production modeling and completion strategies.

Full Course Outline


  • Pore Pressure Theory (2hrs)
    • Pore pressure and abnormal pressure – typical profiles
    • Overpressure generation mechanisms
    • Pore pressure prediction methods
    • Relationship to fracture gradient and WBS models
    • Well planning

  • Application of Pore Pressure Prediction to Unconventional Resources (2hrs)
    • Pressure measurements in tight rocks (sparse data, DFITs, SHmin, drilling data)
    • Difficulties in pressure detection 
    • Identifying shales – ‘Shale-rich’ and the fact that 'sands' to 'shales' is far less clear in unconventionals so the practitioner needs to be more open to using multiple facies rather than just 'shales'.
    • Understand burial histories
    • Understand TOC (RP models, TOC estimation methods)
    • Methods for prediction (Vs, Rho, Vp-VES)
    • Integrated workflows for property prediction

Case studies (2hrs)

  • Ultra-deep and Ultra-safe: Combining facies predictions and PPFG well planning for the ultra-deep water Ayame-1X exploration well, Côte d’Ivoire (Edwards et al., 2017) – An example of conventional pore pressure prediction and the importance of integrated workflows for well planning.

  • Using Traditional Methods to Predict Pore Pressure in Devonian Black Shale Basins of North East British Columbia (Green et al., 2018) – An example of using non-traditional approaches to estimate pore pressure prediction in unconventional plays. 

  • Seismic-based de-risking of unconventional plays by integrating rock physics, inversion, geopressure, and geomechanics (Green et al., 2018) – Highlights the value of building robust, high fidelity elastic property models for a complete understanding of the 3D pressure and stress variation leading to safer, more efficient drilling campaigns.

  • Can Seismic Inversion Be Used for Geomechanics? A Casing Deformation Example (Meyer et al., 2018) – Highlights the value of truly integrated workflows in order to build more robust geomechanical models to help improve well performance.
