Pore Pressure Profile Modelling - for exploration prospectivity and well planning. (Skulduggery or Science ?)
by Ray Pratt – Nexen (presenter), Tim Herrett – Rose Trent, Peter Stone – Rose Trent.
Abstract
- Briefly define geopressure systems, their causes and consequences from an exploration perspective and from a drilling perspective.
- Present the results of two pressure studies undertaken for Norwegian Prospects Fridolf and Geri Freki (Quads 33 and 34). The purpose of the study was to generate pore pressure profiles of nearby wells, in a consistent manner, in order to generate pore pressure profiles for the prospects
- Explain the methodology used to generate the results
- Introduce the pore Pressure Evaluation Software (BLAISE) used in the study
The worlds most recent Pore Pressure Calamity - (natural or man made ?)
Merapi volcano and a major earthquake in Yogyakarta. Now, a heavily populated region of East Java has been consumed by an unstoppable "mud volcano" that may have been caused by a gas- and oil-drilling project
