This article describes a program designed to aid the reservoir engineer and that run within the Lotus 1-2-3 spreadsheet program. BHPCUM allows the engineer to calculate reserves of a gas reservoir based on pressure data and cumulative production data. The user inputs either surface pressures or bottomhole-measured pressures. The program then determines the well reserves by curve fitting the data points and projecting to a gas in place and recoverable gas volumes. A plot of the cumulative production and pressures also is generated. The bottomhole pressure (BHP) divided by the compressibility Z factor plotted against the cumulative production is a graphical representation of the material balance calculation of a gas well. These pressure-production points, when plotted on coordinate scale, will fall on a straight line if well conditions have stabilized and there is no significant condensate or water production. Projection of these data points to a zero pressure would represent the total gas in place. This line can then be backed up to the abandonment pressure. The volume at this point would represent the recoverable gas. An example of this plot is shown.
