Welded vs threaded casing

WELDED
Lower well construction costs - slim hole opportunities
High maximum torque available for casing rotation
Enhanced cement jobs with casing rotation

High strength and better casing integrity
THREADED
Higher well construction cost
Larger well diameter & volume drilling fluid & cement
Less torque for casing rotation
Poor cement jobs without casing rotation
Weaker casing strengthless casing integrity

Field-Proven Run-In-Hole Speed:

5 hours to run 4½in casing to 3,000 ft depth

Frictionless RIH with coupling-free design
