How to ensure proper make-up of premium shouldered tubular connectors
This article presents a new method of monitoring make-up of premium shouldered connections that has been employed to help ensure seal integrity of critical service tubular joints. It can be used both in the mill while bucking on collars and on the rig during casing or tubing runs. The key to the technique is the method used to monitor torque versus time during joint make-up. With today's deeper, more crucial and expensive wells, an increasing number of oil and gas operators are using premium tubular connections for critical service applications where leaks can lead to structural failure of tubing or casing with catastrophic consequences. Premium connections may help alleviate this problem by providing greater seal integrity than API 8-round or buttress, provided they are carefully handled and properly made up. The technique described has been used by Mobil to monitor the make-up of premium shouldered connections, thus providing the mill inspector or drilling supervisor with a quantitative tool for assessing the integrity of connection threads and seals.
