Slug Test Type

Slug tests are conducted by extracting a small volume of fluid from the reservoir within a short period of time. Although the tests and solution methods were developed independently, the analytic solutions for analyzing slug tests are identical to PITA analysis.

Note:

In WellTest, the PITA analysis has been developed further than slug.

PITA facilitates the estimation of p*, reservoir permeability, and skin whereas Slug's Impulse Radial Analysis only provides an estimation of p*. Therefore, PITA is recommended for analyzing data from slug tests. Both PITA and Slug tests have identical modeling capabilities in WellTest.
