Annotation:

This work is focused on the development of an approach to determining the optimal horizontal wells placement for offshore gas reservoir based on hydrodynamic modeling. The concept of using a simplified hydrodynamic model on which multivariate calculations are performed in a simulator is proposed. The determined optimal position of the wells on a simplified model is subsequently transferred to a full-scale hydrodynamic model, and the technological indicators of the development are calculated. A comparison of the accepted well placement with the optimized well position is performed. Variant wells optimized position shows a large economic efficiency by increasing gas production plateau.
