Critical flow rate to avoid water coning
WebJan 1, 1988 · This chapter discusses water coning based on some relatively simple analytical models describing one or more aspects of the coning phenomenon under highly idealized conditions. These models have in common that they are based on the concept of segregated flow in which water and gas are to be separated by a sharp interface. WebPredicting Coning Most prediction methods for coning predict a "critical rate" at which a stable cone can exist from the fluid contact to the nearest ...
