Sunjoto Shape Factor under Full Penetration Slug Test

Thinzar Aye, S. Sunjoto, and Djoko Luknanto

Abstract— Sunjoto developed shape factor equations in order to determine the drawdown and hydraulic conductivity value. Many researchers had conducted research using these equations under the pump test. Moreover, most of the research used Sunjoto equations as the comparison with the other pump test equations. Since 1951, shape factor equations have been developed to determine hydraulic conductivity value under slug test which mainly focus on the dimension of well. Afterwards, many scientists and researchers developed shape factor equations including Sunjoto, Bouwer and Rice. Therefore, this research intends to use Sunjoto equation under the slug test. The comparison of hydraulic conductivity by constant head test and slug test has been conducted in this research. The comparison value is acceptable although there are difference values that were caused by disturb and Un-disturb sample.

Index Terms— Constant head test, hydraulic conductivity value, and Sunjoto shape factor.
