Production Casing &Amp; Tubing Oilfield Basics

Oct 18, 2018 Production tubing is typically anywhere from 1 7/8″ to 2 7/8″ wide. This is literally a string of tubing that is lowered into the well by a workover rig later in the well’s life. Some companies even just install production tubing before they begin producing the well so that it won’t lose its ability to lift fluid naturally as soon.
