... Abstract Typically, in the presence of water coning, a water-free production is economically unattainable since critical rates are too small. Downhole water sink (DWS) technology has been proved and demonstrated as capable of significantly increasing critical rates. In actual practices, however...

... at reservoir conditions, as well as a novel experimental methodology and data processing technique for critical rate determination. A baseline permeability is established at a very low production rate. The rate is subsequently increased in a step wise fashion, returning to the established base rate after every...

... of a producing well. The maximum water-free production rate, referred to as the critical rate, is a function of the thickness of the oil zone, the length of the completion interval, the distance between the completion interval and the water zone, the density of the Oil and water, the viscosity of the oil...
