Recommended Practice 79-3 is one of three API documents on tripping operations. The others are: •Recommended Practice 79-1, Tripping Operations in Hydrostatically Overbalanced Wells, 1st Edition •Recommended Practice 79-2, Tripping Operations with Surface Backpressure Managed Pressure Drilling with Surface Blowout Preventer, 1st Edition
