Understanding the geomechanics of the naturally fractured Juro-Cretaceous Nikanassin Formation in the Deep Basin near Grande Prairie, AB has the potential to improve gas and oil production from that zone. The determination of safe mud weight windows and stress concentrations is important for the planning of future wellbore trajectories. This study focuses on:

• Drilling experience
• Image log analysis and horizontal stress direction
• Minimum principal stress, vertical stress and pore pressure
• Log and rock properties analysis
• Maximum horizontal stress determination
• Model verification
• Wellbore stability
