A TI 59 program is presented which calculates downhole steam quality, steam enthalpy, and heat injection rate as a function of time. The basic calculation technique used in the program is taken from the available literature with modifications to permit use of the programmable calculator. Both concentric and eccentric tubing cases are considered. The program has been validated against several other computer simulations and checks quite favorably in all cases.
