Water Cone Subsidence Time Of A Horizontal Well

Abstract

Abstract Because of a localized decrease in pressure, water may rise to a height above the oil-water interface and be produced through a horizontal well. The localized increase in the water-oil interface elevation creates a cone of water near the well. If a large enough drawdown is exerted on the reservoir, water will start replacing the oil in the production stream. The instant when water first enters the well is known as the critical drawdown or threshold drawdown. As the…
