Here, Jason Linaker, Managing Director at kwik-ZIP, discusses four benefits of using centralizers for drilling projects and what you should look for when choosing a centralizer system. Keeping pipes centralised. The primary function of centralizers is to keep the …

Max-R™ Low Friction Centralizers
Max-R™ Low Friction Centralizers

Max-R™ is a range of patented low friction composite drilling and completions centralizers that has been made specifically for today’s extended reach operations. Max-R™ centralizers are designed to convey well screens, completion tool strings and typical casing and tubing strings into highly deviated and challenging horizontal wellbores.

Centralizers are used in a wellbore so as to get the primary cementing job done effectively. A Bow-Spring Centralizer helps in the even distribution of cement slurry in the casing string. There are two types of Bow-Spring Centralizers: 1. Welded Bow-Spring Centralizers – These centralizers can be slip-on or hinged type centralizers.

6/1/2021, · Last Updated on Wed, 06 Jan 2021 | Oil Well Drilling The purpose of centralizers on casing is to provide separation for the casing from the wall of the hole. This separation is called standoff. The strength of a centralizer is the amount of force required to compress its bows a given distance.

Bow-Spring, Centralizer is, a bow-shaped metal strip used to centralize the casing in a borehole, so as to, improve the efficiency of cementing,. If the casing is touching the formation at any part of the hole, then cement slurry would not pass through the area of contact resulting in a poor cementing job.
