Laser Casing Welding

SPECS

• Fully automated orbital welding
• Pipe connection control screen
• N2 injection at the welding area for safety
• Cutting casing at rig floor (30 minutes to change from weld to cut)
• Ultrasonic control of the weld for each pipe at the rig floor
• Recording welding and ultrasonic for each pipe

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

CASING RUNNING SPEED

5 hours running in the hole speed for 41/2" casing @ 3000 ft depth
