1. Hydraulic Fracturing Design:

Knowing the Shmin is oriented North-South means that fractures will tend to propagate in that direction. To maximize the effectiveness of hydraulic fracturing, we would design the fracture stimulation to align with the North-South orientation. This could involve:

• Fracking Stage Design: Spacing and placement of fracking stages along the wellbore would be planned to create a fracture network oriented in the North-South direction.
• Fluid Injection Strategy: The volume and rate of fluid injection would be adjusted to encourage fracture growth predominantly in the North-South direction.

2. Potential Risk and Mitigation:

One potential risk associated with not considering the Shmin is fracture growth in an undesired direction, potentially creating a fracture network that doesn't effectively connect to the production zone or even breaching into adjacent wells.

To mitigate this risk, we would:

• Use advanced fracking techniques: Implement techniques like multi-stage fracturing with controlled injection rates to guide fracture growth in the desired direction.
• Monitor fracture propagation: Employ micro-seismic monitoring during fracturing operations to closely observe the direction of fracture growth and adjust the fracking strategy accordingly.
• Consider alternative well designs: If the Shmin is highly unfavorable for the current well design, explore alternative wellbore orientations or completion methods to achieve optimal stimulation.
