6.5 Tests Utilizing Early-Time Data
Analysis of early-time data may yield adequate approximations of kh. Such an analysis may be necessary only when middle-time data are not available. As mentioned in the previous section, a desuperposition of buildup data can give the equivalent of a drawdown plot and may be analyzed as such. Consequently, the discussions related to the early-time flow required in Chapter 5 generally apply to buildup tests as they do to drawdown tests.
