Pore pressure predictions and transformations that make use of seismic velocity measurements have a huge impact on drilling safety and the economics of drilling design and well construction. The seismic velocity method provides the pathway for building high-resolution spatial 3D pore pressure models that are subject to continuous calibration, correlation, and correction. As pore pressure distribution reflects the superposition of many influences, the seismic velocity model has to be developed in harmony with both structural and lithologic geologic models.
Pore pressure prediction is a process that involves multidisciplinary technologies and applications that contribute to and constrain the solution. The key to successful pressure prediction is the integration of the supporting technologies at the data level, technology level, and visualization level. Our Pore Pressure Prediction solution provides a comprehensive solution for pore pressure prediction at the wellbore or throughout the subsurface field.
A Complete Solution
Paradigm integrates velocity, lithology, and structural data to constrain the pore pressure prediction using a 3D shared earth model, resulting in:
- Rapid project turnaround with automation of velocity measurement and high levels of interactivity and visualization
- Prediction of pore pressure at the wellbore and away from the wellbore with velocity measurement and modeling
- An understanding of the superposition of controlling influences with the ability to model and visualize them
- Flexibility to recognize and adapt to basin differences
Optimized Program Design
Anticipating potential wellbore destabilization can significantly affect the design of the casing and fluid program. Pore pressure prediction is becoming an indispensable asset evaluation tool for:
- Structural deformation (strain) analysis
- Hydrocarbon column height estimation, seal integrity and migration pathway analysis, and field compartmentalization
- Well planning with drilling engineering for well casing design that determines wellbore stability and optimum casing seat selection and mud programs
- Integration and calibration of pre-drill predictions with real-time measurement and rapid model updating
Fewer Wellbore Problems
Accurate pore pressure prediction can help prevent a variety of wellbore stability problems:
- Wellbore collapse
- Lost circulation
- Stuck pipe
- Casing collapse
- Reservoir damage
- Inability to acquire logging data
- Complete loss of the wellbore
