The number of drilling horizontal wells and wells of complex design is increasing constantly due to reservoir development complexity. These wells are used for low permeable reservoirs and under-gas-cap zone development. This is why we are going to stress the following areas at the session:

• Modeling of oil rim development with horizontal wells 
• Modeling of efficiency improvement in low permeable field development through complex design wells
• Approaches to complex design wells modeling (horizontal wells with multistage hydraulic fracturing and multilateral wells)
• Reservoir model improvement based on horizontal wells survey and monitoring: case studies
• Geomechanical modeling for complex design well drilling
• Integrated hydrodynamic and geotechnical field models
