... permeability and to a lesser degree by aquifer thickness. Introduction Water coning, during which bottom water gradually or abruptly breaks into an oil- or gas-producing well, has long been a problem in oil fields. It is a very complex problem and has been investigated by many researchers. Reservoir...
