AUTOMATED CASING LASER WELDING

Reduce cost of well construction and CO2 emission
by replacing expensive threaded couplings of casing pipes with
reliable, durable and inexpensive welded connections

170+ casing welding jobs done since 2019

Caspian region 170+ casing welding jobs made since 2019

MENA region few pilot jobs
scheduled for H2 2025

4 VALUES FOR INDUSTRY

Existing well construction
70% savings for threads
30% less metal consumption
High casing strength and improved casing integrity
Slim well design (no couplings)
20% total well cost reduction
Drilling with the casing
3 times higher torque for casing rotation
Left and right casing rotation
Easy run in hole - no couplings
102 tonnes of CO2 reduction per welll

SPECS

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

WELDED VS THREADED CASING

WELDED
lower well construction costs -slim hole opportunities

maximum torque available for casing rotation

enhanced cement jobs with casing rotation

high strength & better casing integrity
THREADED
higher well construction cost

larger well diameter & volume drilling fluid & cement

less torque for casing rotation

poor cement jobs with out casing rotation

weaker casing strengthless casing integrity

CASING RUNNING SPEED

Actual casing 41/2" casing runnig in hole time log
Running speed 5 hrs for 1000m of 41/2" casing
