PREDICTING THE BEHAVIOR OF WATER AND GAS CONING IN HORIZONTAL WELLS
Coning is a term used to describe the mechanism underlying the upward movement of water and/or the down movement of gas into the perforations of a producing well. Coning can seriously impact the well productivity and influence the degree of depletion and the overall recovery efficiency of the oil reservoirs. Delaying the encroachment and production of gas and water are essentially the controlling factors in maximizing the field’s ultimate oil recovery. Since coning can have an important influence on operations, recovery, and economics, it is the objective of this paper to develop a computer program for calculating the critical oil (or gas) rate to avoid coning of unwanted fluids into production wells and to predict the behavior of water and gas coning in horizontal wells.
