Improved casing and riser wear technology

Witryna1 sty 2024 · Abstract. The Gating and riser system design play very important role for improving casting yield. These defects can be reduced by making suitable changes in feeding constraints, such as feeder ... Witrynathe casing.The rotating tool joint can severely wear the casing, resulting in damage, expensive repairs, tie-backs and downtime. Installing a WWT Non-Rotating Protector directly above the tool joint prevents tool joint contact. Installing WWT NRPs on each joint of pipe in the high contact areas of the wellbore provides optimal casing protection

A Prediction Model of Casing Wear in Extended-Reach Drilling …

WitrynaRiser wear is primarily a function of riser curvature, which is dependent on riser stiffness, environmental loading, vessel offset, drilling operational parameters and drilling mud properties. Wear allowance and windows for conducting drilling operations can be defined prior to wear analysis. WitrynaThis program applies wear technology to predict casing and riser wear to be expected during drilling operations. The observations and opinions expressed in these articles are based on my 20-year association with the subject of casing and riser wear. Much of this time was spent at Maurer Engineering, under the direction of Dr. W. C. Maurer.
