... in the hot water zone and its rate of advance, the fluid saturation profile and its rate of advance. The location of the steam front at any time can be calculated by the equations of Mandl and Volek who showed that before a critical time tc, the steam zone can be described by the equations of Marx...

... Abstract Sucker rod pumping is the oldest artificial lift method used in production of oil wells. This method is usually designed and analyzed with the assistance of programs based on simplified models, such as the API RP 11L 1 , 2 , or with a wave equation simulator 3 , 4 , 5 . In many...
