Advancing a bottom hole assembly into a wellbore

Abstract

A method can include deploying a tubular string into a perforated section of a wellbore, and introducing a diverting agent into a fluid flow in an annulus surrounding the tubular string, the diverting agent blocking the fluid flow through a set of perforations in the perforated section, thereby increasing a flow rate of the fluid flow in the annulus surrounding the tubular string and advancing the tubular string through the wellbore. Another method can include deploying a tubular string into a perforated section of a wellbore, the perforated section including multiple sets of perforations, a first set of the perforations being positioned uphole of a second set of the perforations, and blocking the first set of the perforations, thereby increasing a flow rate of fluid flow in an annulus surrounding the tubular string and advancing the tubular string through the wellbore.
