SIMULATION SHOWS EFFECTIVENESS OF DOWNHOLE CHOKES IN HORIZONTAL WELLS

Roger Tallby Den norske stats oljeselskap AS Stavanger, Norway Jostein Alvestad, Adolfo Henriquez Den norske stats oljeselskap AS Trondheim, Norway Simulation demonstrates that a much better performance can be expected from a horizontal drain if different zones are isolated and inflow from each zone is controlled by downhole chokes. This technology is well suited for thin oil zones, reservoirs with dipping layers with different permeabilities, and completions where damage governs inflow
