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.
