The type curve method is can be applied to time-drawdown, time-distance drawdown plots, and, for some conceptual models, to distance-drawdown plots.
When the type curve is displayed, the "Value" floating window opens showing the selected wells (or observation points on distance-drawdown plot) as well as the estimated parameters for the displayed type curve.
Normally, the method is applied to the entire diagnostic curve.
