Prediction of pore pressure is vital for safe and economic well planning.
Industry standard velocity-based pore pressure prediction methods (e.g. Bowers, Eaton) assume disequilibrium compaction under uniaxial conditions. However, more sophisticated velocity-based methods can be employed in complex settings (e.g. near salt structures or under tectonic compression), whereby predictions are based on the full stress tensor, obtained through geomechanical modelling.
Rockfield’s integrated seismic field characterisation / definition and pore pressure prediction workflow, housed within the Elfen Horizon software, facilitates rapid generation of complex, 2D or 3D static geomechanical models (e.g. comprising clastic stratigraphy and salt) directly from seismic velocity data (SEG-Y). The models compute field-wide pore pressure predictions; a range of outputs and assessment tools are available to aid well planning, evaluate drilling risks and inform wellbore / casing design.
Elfen’s flexibility and modelling power has allowed it to be successfully utilised in a wide range of industries. We have developed specialist software modules to cater towards your specific industry.
Using our geomachenical finite software Elfen Horizon offers an efficient and intuitive UI and analysis tool to gain an understanding of the subsurface material and stress state.
