Characterisation of the three dimensional state of stress helps you to optimise your field development strategy, predict wellbore instability, fracture permeability, flow anisotropy and reservoir compressibility.

GeoScience can assess the stress field in the reservoir by integrating data from drilling, logging, testing and production, working at both wellbore scale and field scale. We have proven the validity of our approach over many years, carrying out assessments for fields in the North Sea and around the world, in applications such as wellbore stability, sand production and hydraulic fracturing performance.

Horizontal stresses are neither isotropic nor a simple function of the vertical stress, but our methodology provides a cost effective means of accurately assessing the state of stress, enabling you to:

• Reduce formation and borehole damage
• Minimise wells lost to solids production
• Minimise wells lost to water breakthrough
• Optimise field development strategies
• Understand zones of influence of CRI/PWRI operations
• Optimise well placement in fractured reservoirs
• Understand the impact on fracture permeability (critical shear)
