A complete package for 1D to 3D pressure analysis and prediction. Combines geophysics, geology, rock-physics geomechanics, drilling data, and global analogs to build robust, geologically driven pressure and stress models. Quickly analyze pressure and stress data, integrate all offset well data, seismic data and geological data and assess the uncertainty within these models to gain greater insight into undrilled prospect areas.

Powerful and Intuitive Tools for Pore Pressure and Stress Modeling

Access to all data types in a single platform enables knowledge capture and utilization in consistent pressure and stress workflows. The seamless interaction between pre-drill modeling to real-time monitoring ensures no loss of information for safe and cost-effective well delivery.

2D/3D Pressure and Stress Models

Propagate 1D models into 2D/3D using a wide selection of geostatistical and inversion models. Articulate decisions and maximize safety using best-in-class workflows to effectively communicate well planning and trajectory risks using a clear visualization environment.

Capture Uncertainty

Pore pressure and stress models are derived from multi-disciplinary approaches and as such there are many factors that need to be considered and visualized to effectively capture the uncertainty within these pore pressure and fracture gradient (PPFG) models. The crucial part is the risks are effectively communicated during the well-planning process to all teams involved. Using scenarios and stochastic modeling allows analysts to explore the uncertainty within the datasets and quickly test multiple potential outcomes.

CASE STUDY Reduce Risk and Cost in Frontier Exploration

Challenge: Pore pressure prediction works best in areas where the sediments are young, rapidly deposited, contain similar clay content and are within low temperature environments much like those of Tertiary deltas. The ultra-deep water blocks of Cote d’Ivoire have additional geological complexities that therefore make pore pressure prediction more challenging such as, far offset wells outside survey area, high TOC clays, high geothermal gradients, high net-to-gross.

Solution: One of the key solutions to de-risk the ultra- and deep-water Blocks is to build a geologically sensible geopressure model. Such models rely on a detailed understanding of lithologies, facies and depositional models, e.g. the presence of deep-water turbidites, slope fan channels, stratigraphic pinch-out, and rotated fault blocks. The pressure model constructed must explain the current overpressure occurrences, taking into account the local geology and analogous areas (structure, stresses, temperature, basin history, sedimentation rates, and depositional architecture). Using the model we can then sense check any seismic velocity based interpretations.

Results: Accurate prediction of facies, reservoir properties and pressure. The well was complete on time and ahead of budget with best-in-class, non-productive-time (NPT).

Interpretation of image logs for borehole breakouts, sedimentology and fractures. Interactive geomechanical model building, analysis and scenario modelling. Key features include; surface picking and image log conditioning, static-dynamic property calibration, wellbore stability, stereonets and more.

Seismic-Based Pore Pressure and Stress Modeling
Seismic-Based Pore Pressure and Stress Modeling

Pre-drill estimates of pore pressure are commonly derived from well log data and seismic velocity data assuming a velocity-to-effective stress transforms is appropriate. Some of the many challenges in performing predictions with seismic velocities is down to the quality, calibration, scale, extrapolation, and the geological environment that is present. If valid then these models provide useful and intuitive ways of communicating risks between assets and business units.
