23q

On semilog paper, this equation represents a straight line with a slope of 2.3Q/4 ttT. This equation can be plotted in three different ways: (1) s versus logt, (2) s versus log r, or (3) s versus log t/r2 or log r2/t.

DRAWDOWN-TIME ANALYSIS (s VERSUS logt)

The drawdown measurements s at a constant distance r are plotted against time as shown in Figure 9.8.3. The slope of the line is 2.3Q/4^T and is equal to

If a change in drawdown As is considered for one log cycle, then log (t2/t1) = 1, and this equation reduces to or
