H(o) Slug, 18”

The H(o) Slug™ (pronounced H-naught) is a traditional solid slug that is designed to yield a pre-estimated initial displacement during a slug test. It is specifically designed with tapered ends exceeding an 80 degree angle to reduce the pressure wave that can occur with other solid slugs leading to noisy data and reducing the reliability of test data. Calculated initial displacement is represented by “H(o)*” where H is the calculated distance of instantaneous change at time zero (o) in water level created by the the slug. “H(o)” is the measured initial displacement. It is important to compare calculated H(o)* with measured H(o) as part of the QA/QC of the slug test for checking the reliability of test data. These PVC Slugs are available for popular initial displacement lengths of 12”, 18”, and 24” for two-inch diameter Schedule 40 wells.
