What is the Difference Between Casing and Tubing

Casing and tubing are very popular in the oil industry , all of them have widely use but do you know the difference between the casing and tubing? Next I will tell you the difference between casing and tubing.

What is the Difference Between Casing and Tubing

Casing pipe is generally used for the borehole wall support in the drilling as well as after the completion of a well, so as to make sure the smooth casing running of the drilling process and also the normal procedure of the whole oil well after well completion. Tubing is a pipe that drops right into the wells for the production or injection of fluids.

OCTG casings usually from 20″to 7″ which are run after drilling hole size of 24″,17 1/2″ ,12 1/2″ and 8 1/2″ after running casing string cementing job is done to make a cement barrier for zonal / reservoir isolation so that channeling of reservoir fluid may be prevented. Steel casing pipe is very necessary for smooth drilling operations in deep and ERD wells so that hole collapsing may be got rid of. Tubings are run after drilling. Tubings are of 51/2 to 23/8″ in well completions to safe and cost effective maintenance of wells in production phase of well. Thru tubing we safely and efficiently produce wells according to reservoir volume and nature.
