Drill stem test.

The solutions for the slug test (decreasing flowrate) drill stem test (DST), including wellbore storage and skin effect, were presented by Ramey et al. in 1975. In field data from slug test DSTs, an initial period of constant flowrate can often be ob- served. A new model which includes the initial constant flowrate for a slug test was developed.
