Plug-in Overview

geoSTATE provides comprehensive geomechanical modeling of pressures, stresses and rock properties in subsurface volumes and along well paths. Guided multi-domain workflows seamlessly integrate geological, seismic and well data to create a detailed model of the current 3D state of stresses, pressures and rock properties while substantially reducing your project times. geoSTATE builds on proven industry-standard technology by incorporating advanced patented algorithms developed for highly heterogeneous and anisotropic environments, as found in deep water and unconventional shale plays.


  • Predict pressure regimes and wellbore stability ahead of drilling to optimize well design and drilling performance.
  • Bring critical geomechanical analyses in-house to reduce the time and expense associated with outsourcing.
  • Increase productivity and ensure data integrity through seamless integration with existing Petrel data and workflows.
  • Minimize training requirements through intuitive workflows in the familiar Petrel user interface.
  • Achieve efficient multi-disciplinary workflows between drilling, geology, geophysics and petrophysics.
  • Model and predict key pressure, stress and rock properties rapidly in 3D or along well paths using seismic velocity data and/or well logs
  • Incorporate different data types easily for model calibration
  • Calibrate the normal compaction trend interactively for multiple velocity regions
  • Model multiple stress regimes (normal, strike-slip, reverse) along a well
  • Account for sand body effects such as laterial transfer and buoyancy, including hydrocarbon column heights
  • Account for crustal unloading (isostatic rebound) effects
  • Gain accurate mud weight predictions through use of unique plastic failure model
  • Visualize results in standard log view template and interactive hemisphere plots
Geology-Driven Geomechanics for Informed Operational Decisions

As operators move further into deep water subsalt domains and onshore plays with complex behavior, understanding stress effects in the reservoir and surrounding formations becomes increasingly important for making the right decisions throughout the life of the field. Exploration strategies should be guided by identifying field-scale fluid pressure zones and rock stress conditions in the areas of interest. Development relies on characterization of the geomechanical response of reservoirs, resulting in improved development economics, drilling safety and ultimate hydrocarbon recovery. Drilling and completion operations are significantly improved from understanding well-scale effects of rock and fluid behavior.

A Coupled 1D-3D Approach for Comprehensive Modeling

geoSTATE provides comprehensive and consistent geomechanical modeling of pressures, stresses and rock properties both in subsurface volumes and along well paths. This coupled modeling approach delivers improved knowledge of pressure and stress states in the reservoir and surrounding formations, allowing optimization of exploration and development strategies and improved drilling efficiency and safety.

Pore Pressure Prediction for Reduced Drilling Risk

Accurate pore pressure prediction is key to well trajectory and engineering design and the successful management of drilling risk. geoSTATE provides the ability to correctly anticipate and react to complex pressure regimes during planning and execution of drilling programs.

Wellbore Stability Analysis for Reduced Drilling Cost

Wellbore stability problems, including well collapse, stuck pipe, lost circulation and gas kicks, introduce significant additional cost to many wells that are drilled. geoSTATE provides the ability to evaluate proposed trajectories, calculate optimal mud weights and potentially reduce the number of required casing strings.

An Integrated Solution for Multi-Disciplinary Collaboration

Geomechanics-related workflows and analyses include aspects of structural geology, 3D seismic, petrophysics, drilling and fracture simulation. geoSTATE is able to leverage existing data types and functions across a wide range of geotechnical disciplines and seamlessly provide results to relevant workflows. This integrated approach ensures data integrity and workflow efficiency throughout the project.

An Easy to Use Tool for Generalists and Experts

The geoSTATE interface is implemented as an intuitive guided workflow in which calculation steps are presented in a logical sequence to allow both experts and general users to become productive in a short time, with minimum training. Calculation steps support both basic and advanced options to allow rapid creation of first-pass or detailed models as required. Logical default settings are used to provide users a quick look with minimal user input, and updated plots are generated at every step providing immediate feedback when constants are adjusted.
