+*Variables
+**q = current production rate
+**q i = initial production rate (start of production)
+**d i = initial nominal decline rate at t = 0
+**t = cumulative time since start of production
+**N p = cumulative production being analyzed
+**A simple formula – often the most optimistic case
+*Plot of log rate vs. cumulative production is a straight line on semi-log plot
